Pedestrianizing Istanbul's Historic Peninsula

SECTION 1

INTRODUCTION
Istanbul's world heritage-listed Historic
Peninsula is internationally recognized for its
outstanding universal value. Unfortunately, its
rich heritage has been strangled by rapid and
initially uncontrolled urban growth. Concerns
over the preservation of the rich cultural and
historical heritage have increased during the
past decade. In response to raising concerns,
local administrations have initiated numerous
projects in an effort to protect the city’s 8,000
year old Historic Peninsula. As part of these
efforts, Istanbul Metropolitan Municipality and
Fatih Municipality pedestrianized more than 250
streets between 2010 and 2012.
EMBARQ Türkiye is dedicated to working
with local administration and stakeholders for
developing solutions for protecting the area.
In this line, EMBARQ Türkiye invited GEHL
Architects to conduct a public space and
public life survey in the area. The project report
included mapping of the major potentials
and challenges that the Historic Peninsula
experiences in its present state and a survey of
the public life taking place in selected areas. The
first report studied the Historic Peninsula as a
whole, drew attention to current and potential
problems and offered recommendations for
improvement.
In this second report, a more focused approach
had been taken with the aim of assessing
completed pedestrianization projects in
the Historic Peninsula. Pedestrianization
projects from all over the world have shown
that transforming car-oriented streets into
pedestrianized environments has many potential
benefits: Supporting physical activity, social

interaction, economic activity, and improved
air quality. However, these benefits can only be
achieved through successful implementation
of complementary measures. Supporting
infrastructure (e.g. improved streetscapes,
sufficient public transportation options,
availability of car parks) and stakeholder
buy-in are vital for ensuring the success of
pedestrianization projects. In this line, the
present study aimed to provide more details on
completed projects and shed light on the local
community's perceptions of benefits.
Section 2 starts with some background to
the Historic Peninsula and presents details
of pedestrian transformation projects that
were successfully implemented since 2010.
It also highlights planned and ongoing public
transportation projects for the peninsula, which
will significantly alter current conditions. Section
3 provides some theoretical background to
assess economics and air quality benefits of
pedestrianization projects. This background
was valuable in refining the questions for
the perception survey. Finally, Section 4
presents the results from the perception
survey conducted with business owners and
employees on the pedestrianized streets.
We believe these findings will be valuable for (i)
promoting and drawing investments for future
pedestrianization projects as it shows that
stakeholder are mostly happy with the results,
and (ii) encouraging local administrations to
improve ongoing and future pedestrianization
projects as the results highlight priority areas for
improvement.

pedestrianization
projects in the
historic
peninsula
Istanbul Metropolitan Municipality and Fatih Municipality
have been working on pedestrianization projects in the
Historic Peninsula since 2010. More than 250 streets were
pedestrianized in Eminönü, Laleli, and Hocapaşa.
2.1 the Historic Peninsula
A vital part of Istanbul’s historic and cultural
legacy
The Byzantine city walls, the Golden Horn,
and the Marmara Sea surround the Historic
Peninsula. Recent findings show that the
Historic Peninsula was settled back in the
Neolithic period in the 7th millennium BC. This
area harbored many civilizations throughout
its thousands of years of history, thus its
name Historic Peninsula.

It is currently a significant historical, touristic
and commercial center of İstanbul, and also
a busy public transport hub. Its rich historical
and cultural heritage makes the peninsula
a challenging area for transport and urban
planners. The chaotic network of historic
and narrow streets presents challenges
for accessibility and creates high levels of
congestion. In addition, the threat of pollution
arising from industrialization and rapid
urbanization has jeopardized the historical
and cultural heritage of the old town. Now,
both international and national organizations
work very hard to ensure preservation and
conservation of the area.

2.3 RULES AND POLICIES

Existing levels and expected increase of the
peninsula’s daytime population is a significant cause
for concern and calls for careful transport and urban
planning. As suggested earlier, rich historical and
cultural heritage adds extra challenge to planning
efforts. The Cultural and Natural Heritage Preservation
Board has already raised concerns over vibrations
caused by heavy vehicle traffic damaging the Basilica
Cistern, in 2011.

Figure 1 Distribution of Functions (GEHL, 2010)

A series of supporting rules passed by the
Transportation Coordination Center (UKOME) aims
to minimize negative impacts of pedestrianization on
tourism and commercial activities in the area:
•	Streets will be open only to pedestrians between
certain hours during the day. Limited vehicle
access will be allowed at other times;
•	Only official vehicles such as vehicles belonging to
embassies, the police, the postal service, banks
and the fire department as well as ambulances will
be allowed to enter the area during daytime;
•	Commercial permit holders will be allowed to
access the area after work hours for deliveries;
•	Municipal police officers from Fatih Municipality
are tasked with monitoring the implementations;
•	Streets traders are not allowed in selected
pedestrianized streets;
•	Tourist buses are allowed to use the new
route and stops as defined by UKOME in the
neighborhood.

As part of municipal efforts to improve the quality
of life in the area, Istanbul Metropolitan Municipality
started pedestrian-only transformation projects at
Sultanahmet Square in 2010. This was followed
by pedestrianization of 256 streets by the Fatih
Municipality between 2010-2012 in Eminönü,
Tahtakale, Beyazıt, Laleli, Gedikpaşa, and Hocapaşa.
The municipality also carries out supporting
infrastructure projects for the pedestrianized areas
including repaving the newly pedestrianized streets
with granite pavestones, traffic signalization,
waste management, etc. Details of completed
pedestrianization projects are presented in Table 2.
Legal framework for pedestrianization projects

Distribution of functions
The Historic Peninsula offers a diversity of functions,
mostly in clusters, as presented in Figure 1.
The large share of commercial and business
activities in the center and lack of residents leave
1 The Archaeological Park, at the tip of the Historic
Peninsula; the Suleymaniye quarter with Suleymaniye
Mosque complex, bazaars and vernacular settlement
around it; the Zeyrek area of settlement around the
Zeyrek Mosque; and the area along both sides of the
Theodosian land walls including remains of the former
Blachernae Palace.

the district very busy during daytime and deserted
at night. The peninsula has a nighttime population of
approximately 55,635 people in comparison to 2.5
million during the day. Along Ragıp Gümüşpala Street
underpass, pedestrian traffic is busier than most of
the worlds’ busiest main streets in London, New York,
Copenhagen, and Melbourne (GEHL, 2010).

The Transportation Coordination Center (UKOME),
formed under the chairmanship of the İstanbul's
Mayor, is tasked with undertaking planning for
pedestrianization of the streets. UKOME has the
authority to make decisions on major transportation
projects including pedestrianization. UKOME’s duties
are outlined in the Greater City Law dated 10.07.2004.

Public transportation Hub

The Historical Peninsula was added to the UNESCO
World Heritage List in 1985 covering four zones1.
Historic areas in Istanbul are also protected by the
national conservation legislation, and the Historic
Peninsula was declared an archeological site in
1995. The Istanbul Metropolitan Municipality started
transformation projects in an effort to improve the
quality of life in the area, in 2010.

Fatih Municipality defined priority streets for
pedestrianization based on UKOME’s decisions and
accelerated infrastructure works for selected streets.
UKOME has made 16 decisions to pedestrianize
selected areas and identified streets in the Historic
Peninsula between 2005 and 2012. A summary table
outlining these decisions can be found in Appendix B.

The Historic Peninsula also functions as a public
transportation hub, contributing to the high levels
of daytime population. The area is serviced by a
variety of public transport systems including buses,
tram, rail, and ferries. Two new public transport lines
are planned: The metro line extension across the
Golden Horn to Yenikapı, and the rail line across the
Bosphorus (Marmaray Project). These projects will
help strengthen the existing public transportation
network, but will also increase daytime population
in the area. Creating walkable streets and further
pedestrianization will become increasingly important
for the Historic Peninsula.

2.4 future plans
As suggested above, the two new public transport
lines will add to daytime population of the area,
which already is very high at 2.5 million (GEHL,
2010). Creating streets to accommodate pedestrians
visiting or passing through the Historic Peninsula
will be increasingly important. In this line, Fatih
Municipality has plans to pedestrianize more streets
until Marmaray’s projected opening date, 29 October
2013.
Availability of sufficient parking areas for private
car owners is an important aspect to ensure the
success of pedestrianization. This is a vital subject of
improvement for the current pedestrianization projects
as well as the planned ones, as discouraging private
car owners from visiting the peninsula might have
negative impacts on retailers in the area.

ımpacts of
pedestrıanızatıon
projects
Transforming car-oriented streets into pedestrianised
environments has the potential to support physical activity,
social interaction, economic development, and improve air
quality.
Creating walkable communities has many
economic, social, and environmental
benefits. This study focuses on impacts of
pedestrianization on local businesses and air
quality. The rational behind this decision are
summarized below:
•	Pedestrianized areas in the Historic
Peninsula are highly commercialized.
Local business owners and employees
constitute the largest stakeholder group.
Yet, it is generally very hard to get
initial buy-in from local businesses for
pedestrianization projects, as they are
often concerned about reduced footfall.
Fatih Municipality have partnered with
trade unions and business organizations
to inform business owners of expected
benefits of pedestrianization. In this study,
the aim is to get a better understanding
of retailers' perceptions of completed

projects. Their input is valuable as
stakeholder buy-in is vital to ensure
success of these projects. Suggestions
for improvement will also help local
administration to prioritize budget
allocations and projects.
•	Pedestrianization projects aim to minimize
corrosion risks on historical stocks in
the Historic Peninsula by reducing air
pollution levels in the area. Significant
health benefits can also be achieved
through improved air quality, especially
given the high numbers of daily visitors
in the area. Developing methodologies
to quantify benefits of pedestrianization
is vital for promoting these projects.
Therefore, this study aims to understand
whether and how achieved benefits can
be quantified.

3.1 Economic Impacts
Local communities might not initially recognize
economic benefits of pedestrianization projects.
Often, local businesses believe pedestrianization
will adversely affect their revenues due to
reduced traffic and footfall. However, successful
implementations around the world show that
pedestrianization contributes to increased retail
activity. Pedestrianization of Istiklal Caddesi in Istanbul
demonstrated that limiting vehicle access and creating
attractive environments for consumers could improve
business activity.
Table 2 presents a summary of potential economic
benefit categories that should be considered
when evaluating walking improvements (Litman,
2003). Litman highlights the importance of wider
impacts when thinking about economic benefits of
pedestrianization.
Impacts on Businesses
This study aimed to focus more specifically on
impacts of pedestrianization on businesses. A
brief literature review reveals many studies that
suggest positive impacts of similar projects on local
businesses:
•	Sermons and Seredich (2001) identifies benefits
or improving conditions for non-motorized street
users at the vicinity of urban small business:
1. Economic Revitalization and Property Values
– Traffic calming can increase residential and
commercial property values, which attracts
wealthier residents to the area (gentrification)
and can increase retail sales and bring economic
revitalization to a commercial corridor.
2. Attractiveness and Safety – Traffic calming
creates more attractive environments, reduces
auto speed, and increases safety for pedestrians,
bicyclists, drivers, and other users of the street,
which is good for business.
3. Sales and Attracting Customers – Traffic
calming encourages local residents to buy in their
own neighborhoods, and also attracts customers
from a wider area due to reduced travel time,
hassle, and cost. Traffic calming can also help

4. Parking – Most businesses are concerned
about the quality and quantity of customer
parking and access for delivery trucks. However,
too large a supply of subsidized, on-street parking
can harm businesses.
5. Impact on Employees – Poor bicycle,
pedestrian, and transit conditions can harm
businesses by losing worker productivity and
time to gridlock, and by impairing employee
recruitment. Conversely, improved transportation
facilities can provide more convenience for
employees.
6. Construction and Costs – Traffic calming
projects often require only minimal “down time”
for construction, and most do not require any
investment from business owners.
•	Shops within pedestrian areas are more
successful than those outside, as pedestrianized
areas are more attractive for shoppers. Increased

•	A survey of more than 100 cities around the
world, concerning their pedestrianization
schemes, revealed environmental improvement
closely related to the removal of traffic. The survey
also showed that 49% of all the pedestrian areas
developed experienced an upward trend in retail
turnover, while only 18% experienced a decrease,
and %25 stayed stable (OECD 1978). Cities in
Austria, Germany and Scandinavia experienced
increase in turnover of more than 60% (OECD,
1978).
These studies show that successful pedestrianization
projects create better environments for people.
These improvements attract more shoppers, and
increase economic productivity and employment
in pedestrianized areas. Higher turnovers are also
reflected in higher market rents. Individual perceptions
play a vital role in achieving these benefits.
This study investigates the perceived benefits and
disadvantages of pedestrianizing Historic Peninsula.
Interviews were conducted with businesses in the
area based on expected benefits as suggested by the
literature and local administration.

3.2 Impacts on Air Quality
Environmental impacts of emissions from motorized
vehicles in the Historic Peninsula can be analyzed
in two main categories: (i) health impacts, and (ii)
impacts on urban spaces and historical monuments.
Negative impacts are especially significant in urban
areas with high levels of traffic congestion. Main
pollutants from motor vehicles include sulphur oxides
(SOx), carbon monoxide (CO), nitrogen oxides (NOx),
volatile organic compounds (VOC), lead, particulate
matter (PM), and ozone (O3).
Impacts of air quality on health
Table 3 presents the types of health effects
experienced by the most common vehicular pollutants
at elevated levels.

Pedestrianization projects are expected to reduce
vehicle traffic, and thus reduce pollution levels.
However, Istanbul and particularly the study area lacks
sufficient data on pollutants listed above to quantify air
quality impacts on health.
Currently, there is a single Air Quality Measurement
Station in Aksaray. This station is not representative
of pedestrianized streets, as it is located in an area
where there is continuous traffic flow. In other words,
if pedestrianization of streets were successful in
improving air quality, it would not be reflected on
measured pollution levels. Indeed, quantitative
comparisons between 2009 and 2012 pollution
levels for (SO2, NO2, CO, PM10) show no significant
changes.
Impacts of air quality on cultural heritage stocks
Corrosion is another important impact of air pollution
for the Historical Peninsula, as it is home to rich
historical sites. A decade ago, SO2 was considered
one of the most important air quality parameters on
the corrosion of cultural heritage stocks. Significant
increases in the levels of nitrogen compounds, ozone
and fine particulate matter in the ambient air have
been associated with the increasing automobile
traffic; however, a decreasing trend in SO2 levels has
been observed in most parts of Europe and Türkiye.
Scholars continue to study impacts of vehicular
emissions on historical stocks.
Pedestrianizing Istanbul's Historic Peninsula 15

Ferhat Karaca
Associate Professor, Fatih University
"Fatih University Air Quality Research Group completed the most comprehensive study on the air quality for the
Historic Peninsula, and results were published in 2013. Overall, observed levels of pollutants do not pose significant
risks for human health. At the local level, traffic density raises pollutant levels, creating hotspots.
European Commission or Environmental Protection Agency does not have threshold levels for ensuring protection of
heritage stock. Therefore, it is hard to reach conclusions on risk levels for the historical heritage stock in the historical
peninsula. It could be said, however, that observed pollutant levels point to high-risk levels. It is known for a fact that
high NOx, SOx, and PM levels might lead to corrosion of heritage stock. Traffic levels contribute significantly to higher
levels of pollution. Therefore better traffic planning in the area, and transforming the historic peninsula into a traffic
free region is an important step towards protection and conservation of heritage stock in the Historic Peninsula."

Pınar Mengüç
Professor, Özyeğin University
"It is likely that climate change will become the biggest environmental problem in the history of mankind. There
have been changes in the climate before, when the entire history of earth is studied. However, none of these resulted
from human activity and no significant changes were observed during the 10,000-year history of humankind.
High concentrations of greenhouse gases (GHGs), like water vapor, carbon dioxide, and methane absorb energy,
cause changes in Earth’s energy balance in the atmosphere and triggers climate change effects. Fossil fuels used in
transportation, building, and industries are the major cause of increased concentration of GHGs in the atmosphere.
Burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of
particulate matter.
'Particles less than 10 micrometers in diameter (PM10) pose a health concern because they can
be inhaled into and accumulate in the respiratory system. Particles less than 2.5 micrometers in
diameter (PM2.5) are referred to as "fine" particles and are believed to pose the greatest health risks.
Because of their small size, fine particles can lodge deeply into the lungs.' (US EPA)
A recent article published by Lancet showed that surge in car use in India and China is responsible for millions of
premature deaths. Inevitably, all metropolises including Istanbul are faced with the same threat.
Measurements of particulate matter emissions are important for the development of urban transportation policies.
These measurements will also help quantify economic consequences of health impacts. Furthermore, high
particulate matter emissions create significant corrosion risks for historical stocks, which lead to further economic
loss. Fatih University conducted a comprehensive study in the Historic Peninsula for measuring SO2, NO2, CO, and
PM10 levels. Details of this study and its finding are presented in this report. We have developed tools to measure
characteristics for particulates of size 100 nanometers and below. Fatih University and Özyeğin University have
partnered to take this research further. Through our partnership with EMBARQ Turkiye, it is our hope that our work
will have wider benefits for the Historic Peninsula and Istanbul. "

Dr. Ferhat Karaca’s thesis, “Mapping the corrosion
impact of air pollution on the Historical Peninsula of
İstanbul” is the most comprehensive study conducted
so far for evaluating the corrosion levels related to air
quality and the seasonal pollutant (NO2, SO2, and O3)
exposure levels over 50 monitoring stations distributed
on the historical peninsula of Istanbul. Exposure levels
of SO2, NO2, and O3 pollutants in the Historical
Peninsula atmosphere were measured using passive
samplers between October 2008 and August 2009,
seasonal and spatial distribution characteristics of
the pollutants over the region were evaluated, and
high-resolution corrosion impact maps were obtained
on the Historical Peninsula of Istanbul. Findings were
published, and below is a summary of study results
(Karaca, 2013):
•	The SO2 exposure levels in this study indicate a
moderate level of risk for the peninsula. There is
a SO2 hotspot situated between the two largest
university hospitals (Cerrahpasa and Capa). A
very busy road (E-5) passes through the area and
it is most probable that the SO2 exposure levels
around these places have increased as a result of
daytime traffic activities.
•	Both NO2 and SO2 have been attributed to
traffic related distribution, and therefore their
exposure distribution maps have similarities. There
are two hotspots for NO2 exposure during the
spring period: Firstly, the road zone between the
Ataturk bridge and Eminonu, and secondly, an
area centered on the Topkapi junction on the 10.
Yil Avenue (Motorway). Both of these areas are
combined and it is seen that the NO2 exposure
was also stretched from Topkapi Junction into
Fatih District (the midland of the peninsula)
through Turgut Ozal and Adnan Menderes
Avenues during winter.
•	Ozone is a secondary pollutant. The tip of the
peninsula is identified as a hot-spot. The PM10
values during July and August 2010 were
significantly higher than the average value, and no
significant relation was observed with the other
pollutants during these two months.
Findings above suggest that high NO2 and SO2 levels
are attributed to high levels of congestion. Corrosion
effects are observed in the identified areas for high

NO2 and SO2 levels. Pedestrianization projects
are expected to reduce these corrosion effects by
reducing traffic in the area. In assessment of net
impacts of pedestrianization, air quality measurements
before and after project implementation at
pedestrianized sites are required for comparisons.
Unfortunately, these data were not available and net
benefits of completed pedestrianization projects on
corrosion cannot be quantified at this stage.
Quantifying air quality improvements
Quantifying air quality improvements resulting from
pedestrianization is not plausible at this stage due to
large data requirements. Therefore, it is hard to put
a number on the achieved benefits on health and
historical stock. However, it was possible to capture
some of the perceived benefits from improved air
quality through the survey. Further details on the
survey are presented in Section 4.
Conversations with scholars in Türkiye showed
significant level of interest in analyzing air quality
improvements in the Historic Peninsula. Yet, lack
of data hinders researchers. It is important for local
administrations to make the data publicly available to
promote research as quantified benefits from projects
will make it much easier to draw investments to fund
similar projects.
Pedestrianizing Istanbul's Historic Peninsula

SECTION 4

perceptıon
survey
Individual perceptions play a vital role in identifying the full
benefits of pedestrianization. This study investigates the
perceived benefits and disadvantages of pedestrianization
projects in the Historic Peninsula between 2010 and 2012.
4.1 Methodology
While it has not possible to carry out a
complete economic impact analysis within
the scope of this project, this study focused
on four main regions in the Historic Peninsula
and aimed to understand the perceived
effects of pedestrianization on the local
community.
Inputs from academicians (Istanbul Technical
University) and the EMBARQ Network’s
experts were used in designing the survey.
Project Planning and Technical Works
Units at the Fatih Municipality provided
pedestrianization project drawings, which
were used to define the survey area in our
study. Comparative data on function changes
before and after the project completion were
not available. Therefore, it was not possible
to assess the degree of function change in
the pedestrianized regions. However old and
new photographs taken at the area were also
provided for comparison.

Business owners and managers in the area
were surveyed to assess satisfaction levels.
The rational behind the decision to target
businesses are three-fold: (i) businesses
rather than residential buildings dominate
pedestrianized regions and therefore
constitute the largest stakeholder group, (ii)
shoppers are also a large stakholder group,
however most are local and foreign tourists
who are not regular visitors, (iii) achieving
economic benefits from pedestrianization is
only possible if businesses perceive benefits
of these projects and replicate in new
environment.
Survey Area
Pedestrianization projects were implemented
at four main regions of the Historical
Peninsula: Üst Laleli, Alt Laleli, HocapaşaSirkeci and Eminönü-Tahtakale. 256 streets
and roads have been pedestrianized. Sample
areas from each of these regions were
selected to conduct the survey as presented
in Table 4.

On December 3-4 2012, 420 surveys were completed
by business owners and managers located on 39
streets 2012. The surveyors were selected from
university students and they attended a one-day long
briefing meeting prior to field visits.
Inputs from experts in the field
Meetings were held with Dr. Ferhan Gezici and Prof.
Dr. Handan Türkoğlu, Research Assistant Eda Beyazıt
from Istanbul Technical University to receive their
inputs and feedback in defining a methodology for
assessing economic impacts of pedestrianization
through the survey. Their recommendations included
the following:
•	Occupancy rates and workforce changes,
•	Changes in sales volumes,
•	Changes in transport mode choice,
•	Streets where main arterial roads cross with bystreets, and
•	Conducting surveys in four phases: prior to
project, shortly after project declaration, shortly
after project completion, long after (10-20 years)
project completion.
Meetings were held with Laleli Businessmen's
Association (LASIAD) as part of survey design, to
receive some insight about concerns and perceptions
of businesses in the area. LASIAD worked very

closely with Fatih Municipality during renovation of
sidewalks and pavements as part of pedestrianization
works. LASIAD General Secretary Şerafettin Yüzüak
emphasized how much they value rehabilitation
efforts. In this line, LASIAD convinced the municipality
to use natural granite instead of lock paving stones for
12 streets and paid for the additional costs.

4.2 Main Findings
This section presents an overview of the findings
of the perception survey conducted on December
4th and 5th, 2012. The analyses are based on
responses from 423 shops, all of which are located on
pedestrianized streets. Findings from the recent report
by GEHL Architects are also used to support survey
results where relevant. Below is an overview of the
analysis section:
Overview of businesses section presents
characteristics of the shops surveyed and provides
some background on the sample,
Attitudes towards pedestrianization section
provides a summary of current and past attitudes
toward pedestrianization, as well as expectations for
the future,
Changes in sales section aims to provide insights
on observed and expected changes in sales volumes,
customer base, and income,
Property values section presents locals’ perception
on changes in property values as a result of
pedestrianization,
Travel to work looks at transport modal shares,
Parking presents perceptions on available car parking
alternatives,
Urban environment section covers respondents’
perceptions on observed changes in the urban
environment following the completion of the
pedestrianization project.

2010). Pedestrianization and other supporting projects
should aim to increase the diversity in the area in the
future.

Table 5 Representation of areas in the region

Newcomers in the area
17% of the respondents reported that they have
moved to the area within the past five years. Among
these newcomers, 52% noted that they have moved
to the area because they believe there are better
business opportunities, and 20% said that they
wanted to attract more tourists.
While many shop owners aim to attract tourists, GEHL
reported that tourists tend to collect monuments from
their checklist and neglect the remaining splendors of
the city. Creating a better environment for tourists to
walk around the shops promoting social interaction
will help these shops to attract more tourists.

Business types: Domination of wholesales
traders
Business type distributions are presented in Figure 2.
Only 26% of the surveyed shops were solely involved
in retail. Such distribution might not be favorable
for a pedestrianized area, as wholesale traders and
their customers will have higher delivery and logistics
needs. Currently, most wholesale traders are located
in Eminönü and Alt Laleli area, while retailers dominate
Hocapaşa. Üst Laleli has an equal distribution of retail
and wholesale traders. It is expected that the new
pedestrianized area will attract more retail traders.

4.2.2 Attitudes Toward Pedestrianization
It is important to understand what locals think
about the project to ensure its success. Their views,
suggestions, and concerns are valuable for local
authorities to improve current conditions and get
buy-in of businesses in the area. High acceptance and
satisfaction levels are also valuable to get support for
future pedestrianization projects.
Q15 ask respondents their views on pedestrianization
after its completion:
•	78% of respondents were pleased or very pleased
with the results of the project,
•	19% were not pleased or not pleased at all.
Changes in perception
Q14 and Q15 ask respondents if they supported the
pedestrianization at the beginning, and if they are
satisfied with the results at the end. Figure 4 presents
changes in perception through responses to Q14 and
Q15:
•	40% of the respondents supported the project at
the beginning, and 90% of those supporters were
happy with the results;
•	62% of the people who did not have an opinion at
the beginning were happy with the results at the
end;
•	23% of the people who were against the project
at the beginning were happy with the results at
the end.

Such high percentage is reflection of high satisfaction
about the current implementation.

Suggestions to improve current conditions to make
deliveries more convenient include changes to hours
of operation and provision of special permits to shop
owners. 58% of respondents are happy with the
hours, however 41% are not.
4.2.3 Changes in Sales
Pedestrianization projects often aim to increase
economic activity in pedestrianized areas by attracting
more shoppers. However, it is often very challenging
to measure the net effect of pedestrianization
on net sales volumes due to high accurate data
requirements. This survey aimed to measure
perceptions of respondents with regards to observed
and expected changes in sales volumes, rather than
attempting to measure the net effect based on sales
figures. Q18 asks if shops in the area expect their
sales to increase or decrease after pedestrianization:
•	56% expect sales to go up
•	16% expect a decrease in the sales volume.

Q14 asks for more details on expected and observed
changes in staff needs, annual income, and number
of customers, which might be reflective of perceptions
on economic activity (Table 7):
•	Most respondents reported that they did not
observe any changes and are not expecting
any change in the future as a result of
pedestrianization.
•	25% expects increases in their annual income,
and 39% expects an increased customer
numbers.
•	A significant percentage of respondents are
concerned about decreases in their income and
customer numbers.

Problems with deliveries
Q9 asks respondents if logistics and delivery problems
became more of an issue after pedestrianization.
This is important to understand potential impacts of
pedestrianization on businesses:

than before,
•	61% says that there were no additional burdens in
terms of logistics needs.

REMAX, an international real estate company,
provided some initial data on real estate value
changes. Müslüm Deveci and Murat Ergin underlined
the fact that there are numerous factors influencing
the real estate market, and emphasized the challenge
in understanding the net impact of pedestrianization
on prices. Their general opinion was that the
pedestrianization project had a positive impact on the
market, increasing both rental and property values.
Real estate sales price changes between 2010 and
2012 in the area that covers both pedestrianized and
non-pedestrianized streets are presented in Table 8 to
give an idea of the observed changes in the market.

As pedestrianization increases the attractiveness of
the urban areas and creates high quality environment,
it is expected that property values will increase.
However, the net effect of pedestrianization on
property values is often very hard to measure
since there are a lot of external parameters that
affect changes in property values. Furthermore,
academicians consulted suggested that it might take
up to 10 years for researchers to observe increases
in property values after project completion. This
survey therefore aimed to understand perceived and
expected changes in property values.

changes in property values in more detail. Table

property values reported in response to Q22 and Q23.
While most respondents did not observe an increase
in rental or property values, 43% and 39% respectively
are expecting to see a change in the future.

is still important to understand the current situation to
analyze modal shifts in the future. The current shares
reported by survey respondents are presented in
Figure 5. The current share of public transportation is
already high at 65%. The expectation is to see more
people using public transport and walking as their
main mode of travel in their commutes to work.
High share of public transport in Eminönü and
Hocapaşa
Walking’s share is relatively high at 14% in the Alt
Laleli area. Share of public transport is 75% both for
Eminönü and Hocapaşa, which reflects the strong
public transport network serviced by ferries, buses
and tram. Private cars have a significant modal share
in commutes to work everyday at 26%.
Most used public transport mode: Buses
Among public transport users, buses are the most
popular choice with 51%, followed by the tram at
36%. Commuter train services and ferry services both
have share of 5% among public transportation modes.

4.2.5 Travel to Work
It is important to understand the modal distribution
before and after the pedestrianization. The survey
was conducted only three months after the
pedestrianization of these streets were completed,
and did not ask the respondents about their transport
modes before project implementation. While we
currently cannot measure any shifts that did occur, it

Of the 108 respondents who indicated that they
commute to work by car, 93 reported that they use
car parks, and seven of them park their car on the
roadside. It is however important to note that current
car parks are sometimes located on the roadside

Additional two questions were included in the survey
to understand perceptions of availability of parking
space before and after pedestrianization:
•	The majority of the respondents noted that
available parking spaces are adequate (56%),
followed by the 42% who indicated that the
available parking spaces are lower in numbers
than the demand and there is a need for more car
parks.
•	The majority reported that there was no change
in the availability of parking spaces after
pedestrianization (83%).
•	13% of the 176 people who reported that the
parking spaces were not satisfactory prior to
pedestrianization thought that the number of
parking spaces decreased even further.
•	14% of the 236 people who reported that the
parking spaces were adequate thought that the
number of parking spaces increased since the
pedestrianization.

Respondents' recommendations
The survey asks the respondents if they have any
recommendations for additional parking spaces.
Among the 45 recommendations, mostly from car
users, some highlights include:
•	Prices are too high, there might be a lower fee
scheme for local shops;
•	More multi-storey car parks will be beneficial,
•	Building car parks below ground under existing
buildings might be a good option;
•	Specific locations named include: Kumkapı,
Aksaray, Beyazıt, Sarayburnu, near Sirkeci Train
Station.
4.2.6 Urban Environment
Pedestrianization projects aim to improve
streetscapes, reduce noise levels, and improve air
quality. All of these improvements will create better
and healthier living environment and consequently
better experiences for visitors and locals. It is therefore
important to understand perceptions on above noted
components to assess the success of the project.
In this line, the survey asked respondents some
questions on their perceptions of the changes in
noise levels, air quality, and landscape improvement/
planning.

Noise Levels
62% of the respondents thought that noise levels
were very high in the area due to motorized traffic.
91% of these people who were concerned about
the noise levels reported a decrease as a result of
pedestrianization. This is a very positive outcome of
the project reflecting its success in reducing noise
levels.
Air Quality
34% of the respondents thought that air quality,
especially emissions from cars were serious issues for
the area. 86% of these people who were concerned
about emissions and air quality reported better air
quality as a result of pedestrianization.
Clean Streets
Clean streets improve the atmosphere and the image
of a road. 33% of respondents were concerned about
their streets not being clean enough. 85% of these
people who were concerned reported an improvement
after pedestrianization.
Resting Options
GEHL reported an extensive lack of resting options
in terms of public benches along the streets. 58%
of respondents share this view and report that there
is a lack of public benches in the area. However,
85% of these respondents said that there was no
improvement in the availability after pedestrianization.
This highlights a key area for improvement.
Pedestrian Experience
Pedestrians experience several challenges on the
streets in the Historic Peninsula due to limited
availability of space for walking. 61% of respondents
were concerned about such challenges prior to
pedestrianization, and 86% of them reported
improvements achieved afterwards.
Street Sellers
21% of the surveyed shops were concerned about
the growth in the number of individuals who tout for
trade in the Historic Peninsula. Some of these traders
might cause annoyance to the public, and obstruct
footpaths. Most respondents believe that municipality
should be stricter with street sellers.

Insights from interviews with local
business are highly valuable for
local administrations to increase
stakeholder buy-in.

4.3 Conclusions and recommendations

Key areas for improvement

The responses to the survey showed that the
pedestrianization was successful and locals were
largely happy with the results:

Survey results highlighted some key areas for
improvement. These will be valuable for local
authorities to get a grasp on current concerns of the
locals and their expectations.

• 78% of respondents said that they were pleased or
very pleased with the pedestrianization.
• 83% said that they would support pedestrianization
projects in other areas.
• Locals are mostly optimistic about the future:
56% expect sales to increase,
39% expect customer volumes to increase,
25% expect annual income levels to increase,
39% expects property values to increase.
• Current share of public transportation is already
high at 65%. It is the most popular mode in
commutes to work. The expectation is to see more
people shifting to public transportation or walking
from private vehicles.
• Respondents who were concerned about
noise levels and air quality reported significant
improvements.

The locals were expecting better landscape planning
as part of the pedestrianization project (e.g. more
public benches, plants and flowers, infrastructure
improvements for pavements, etc.). However, there
were no changes on pedestrianized streets apart
from physical barriers to prevent motor vehicles from
penetrating. Streetscapes should be improved on
pedestrianized streets.
There are significant concerns over the imposed
difficulties with deliveries to the shops. Further
investigations are required to understand business
concerns in the area, and whether changes to hours
or special permit provisions are required to improve
perceptions. These concerns might decline over time,
as businesses are more familiar with new requirements
and adapt their business operations accordingly.
Decline in sales volumes is another common
concern. Respondents are worried that restricted
vehicle access in their streets might discourage their
customers. It is therefore important to improve the
streetscape to attract customers to these streets.
42% of respondents believe that there is a need for
increased parking spaces to meet the demand.
Furthermore, GEHL Architects report that current
car parks are already located on the roadside and
inappropriate next to monuments. It is therefore
important to improve public transportation services
in the area. If more people shift to alternative modes,
demand for car parks will decrease. This will also
improve streetscapes.
Street sellers are another concern as there is an
increase in their numbers with pedestrianization.
Regulations and associated increased enforcements
to reduce street sellers should be reviewed to ensure
a better environment both for locals and visitors.

  • 3. Pedestrianizing Istanbul's Historic Peninsula SECTION 1 INTRODUCTION Istanbul's world heritage-listed Historic Peninsula is internationally recognized for its outstanding universal value. Unfortunately, its rich heritage has been strangled by rapid and initially uncontrolled urban growth. Concerns over the preservation of the rich cultural and historical heritage have increased during the past decade. In response to raising concerns, local administrations have initiated numerous projects in an effort to protect the city’s 8,000 year old Historic Peninsula. As part of these efforts, Istanbul Metropolitan Municipality and Fatih Municipality pedestrianized more than 250 streets between 2010 and 2012. EMBARQ Türkiye is dedicated to working with local administration and stakeholders for developing solutions for protecting the area. In this line, EMBARQ Türkiye invited GEHL Architects to conduct a public space and public life survey in the area. The project report included mapping of the major potentials and challenges that the Historic Peninsula experiences in its present state and a survey of the public life taking place in selected areas. The first report studied the Historic Peninsula as a whole, drew attention to current and potential problems and offered recommendations for improvement. In this second report, a more focused approach had been taken with the aim of assessing completed pedestrianization projects in the Historic Peninsula. Pedestrianization projects from all over the world have shown that transforming car-oriented streets into pedestrianized environments has many potential benefits: Supporting physical activity, social interaction, economic activity, and improved air quality. However, these benefits can only be achieved through successful implementation of complementary measures. Supporting infrastructure (e.g. improved streetscapes, sufficient public transportation options, availability of car parks) and stakeholder buy-in are vital for ensuring the success of pedestrianization projects. In this line, the present study aimed to provide more details on completed projects and shed light on the local community's perceptions of benefits. Section 2 starts with some background to the Historic Peninsula and presents details of pedestrian transformation projects that were successfully implemented since 2010. It also highlights planned and ongoing public transportation projects for the peninsula, which will significantly alter current conditions. Section 3 provides some theoretical background to assess economics and air quality benefits of pedestrianization projects. This background was valuable in refining the questions for the perception survey. Finally, Section 4 presents the results from the perception survey conducted with business owners and employees on the pedestrianized streets. We believe these findings will be valuable for (i) promoting and drawing investments for future pedestrianization projects as it shows that stakeholder are mostly happy with the results, and (ii) encouraging local administrations to improve ongoing and future pedestrianization projects as the results highlight priority areas for improvement. 3
  • 4. Pedestrianizing Istanbul's Historic Peninsula section 2 pedestrianization projects in the historic peninsula Istanbul Metropolitan Municipality and Fatih Municipality have been working on pedestrianization projects in the Historic Peninsula since 2010. More than 250 streets were pedestrianized in Eminönü, Laleli, and Hocapaşa. 2.1 the Historic Peninsula A vital part of Istanbul’s historic and cultural legacy The Byzantine city walls, the Golden Horn, and the Marmara Sea surround the Historic Peninsula. Recent findings show that the Historic Peninsula was settled back in the Neolithic period in the 7th millennium BC. This area harbored many civilizations throughout its thousands of years of history, thus its name Historic Peninsula. It is currently a significant historical, touristic and commercial center of İstanbul, and also a busy public transport hub. Its rich historical and cultural heritage makes the peninsula a challenging area for transport and urban planners. The chaotic network of historic and narrow streets presents challenges for accessibility and creates high levels of congestion. In addition, the threat of pollution arising from industrialization and rapid urbanization has jeopardized the historical and cultural heritage of the old town. Now, both international and national organizations work very hard to ensure preservation and conservation of the area. 5

As suggested earlier, rich historical and cultural heritage adds extra challenge to planning efforts. The Cultural and Natural Heritage Preservation Board has already raised concerns over vibrations caused by heavy vehicle traffic damaging the Basilica Cistern, in 2011. Figure 1 Distribution of Functions (GEHL, 2010) A series of supporting rules passed by the Transportation Coordination Center (UKOME) aims to minimize negative impacts of pedestrianization on tourism and commercial activities in the area: • Streets will be open only to pedestrians between certain hours during the day. Limited vehicle access will be allowed at other times; • Only official vehicles such as vehicles belonging to embassies, the police, the postal service, banks and the fire department as well as ambulances will be allowed to enter the area during daytime; • Commercial permit holders will be allowed to access the area after work hours for deliveries; • Municipal police officers from Fatih Municipality are tasked with monitoring the implementations; • Streets traders are not allowed in selected pedestrianized streets; • Tourist buses are allowed to use the new route and stops as defined by UKOME in the neighborhood. As part of municipal efforts to improve the quality of life in the area, Istanbul Metropolitan Municipality started pedestrian-only transformation projects at Sultanahmet Square in 2010. This was followed by pedestrianization of 256 streets by the Fatih Municipality between 2010-2012 in Eminönü, Tahtakale, Beyazıt, Laleli, Gedikpaşa, and Hocapaşa. The municipality also carries out supporting infrastructure projects for the pedestrianized areas including repaving the newly pedestrianized streets with granite pavestones, traffic signalization, waste management, etc. Details of completed pedestrianization projects are presented in Table 2. Legal framework for pedestrianization projects Distribution of functions The Historic Peninsula offers a diversity of functions, mostly in clusters, as presented in Figure 1. The large share of commercial and business activities in the center and lack of residents leave 1 The Archaeological Park, at the tip of the Historic Peninsula; the Suleymaniye quarter with Suleymaniye Mosque complex, bazaars and vernacular settlement around it; the Zeyrek area of settlement around the Zeyrek Mosque; and the area along both sides of the Theodosian land walls including remains of the former Blachernae Palace. the district very busy during daytime and deserted at night. The peninsula has a nighttime population of approximately 55,635 people in comparison to 2.5 million during the day. Along Ragıp Gümüşpala Street underpass, pedestrian traffic is busier than most of the worlds’ busiest main streets in London, New York, Copenhagen, and Melbourne (GEHL, 2010). The Transportation Coordination Center (UKOME), formed under the chairmanship of the İstanbul's Mayor, is tasked with undertaking planning for pedestrianization of the streets. UKOME has the authority to make decisions on major transportation projects including pedestrianization. UKOME’s duties are outlined in the Greater City Law dated 10.07.2004. Public transportation Hub The Historical Peninsula was added to the UNESCO World Heritage List in 1985 covering four zones1. Historic areas in Istanbul are also protected by the national conservation legislation, and the Historic Peninsula was declared an archeological site in 1995. The Istanbul Metropolitan Municipality started transformation projects in an effort to improve the quality of life in the area, in 2010. Fatih Municipality defined priority streets for pedestrianization based on UKOME’s decisions and accelerated infrastructure works for selected streets. UKOME has made 16 decisions to pedestrianize selected areas and identified streets in the Historic Peninsula between 2005 and 2012. A summary table outlining these decisions can be found in Appendix B. The Historic Peninsula also functions as a public transportation hub, contributing to the high levels of daytime population. The area is serviced by a variety of public transport systems including buses, tram, rail, and ferries. Two new public transport lines are planned: The metro line extension across the Golden Horn to Yenikapı, and the rail line across the Bosphorus (Marmaray Project). These projects will help strengthen the existing public transportation network, but will also increase daytime population in the area. Creating walkable streets and further pedestrianization will become increasingly important for the Historic Peninsula. 2.4 future plans As suggested above, the two new public transport lines will add to daytime population of the area, which already is very high at 2.5 million (GEHL, 2010). Creating streets to accommodate pedestrians visiting or passing through the Historic Peninsula will be increasingly important. In this line, Fatih Municipality has plans to pedestrianize more streets until Marmaray’s projected opening date, 29 October 2013. Availability of sufficient parking areas for private car owners is an important aspect to ensure the success of pedestrianization. This is a vital subject of improvement for the current pedestrianization projects as well as the planned ones, as discouraging private car owners from visiting the peninsula might have negative impacts on retailers in the area.

  • 7. Pedestrianizing Istanbul's Historic Peninsula sectıon 3 ımpacts of pedestrıanızatıon projects Transforming car-oriented streets into pedestrianised environments has the potential to support physical activity, social interaction, economic development, and improve air quality. Creating walkable communities has many economic, social, and environmental benefits. This study focuses on impacts of pedestrianization on local businesses and air quality. The rational behind this decision are summarized below: • Pedestrianized areas in the Historic Peninsula are highly commercialized. Local business owners and employees constitute the largest stakeholder group. Yet, it is generally very hard to get initial buy-in from local businesses for pedestrianization projects, as they are often concerned about reduced footfall. Fatih Municipality have partnered with trade unions and business organizations to inform business owners of expected benefits of pedestrianization. In this study, the aim is to get a better understanding of retailers' perceptions of completed projects. Their input is valuable as stakeholder buy-in is vital to ensure success of these projects. Suggestions for improvement will also help local administration to prioritize budget allocations and projects. • Pedestrianization projects aim to minimize corrosion risks on historical stocks in the Historic Peninsula by reducing air pollution levels in the area. Significant health benefits can also be achieved through improved air quality, especially given the high numbers of daily visitors in the area. Developing methodologies to quantify benefits of pedestrianization is vital for promoting these projects. Therefore, this study aims to understand whether and how achieved benefits can be quantified. 11
  • 8. 12 Pedestrianizing Istanbul's Historic Peninsula 3.1 Economic Impacts Local communities might not initially recognize economic benefits of pedestrianization projects. Often, local businesses believe pedestrianization will adversely affect their revenues due to reduced traffic and footfall. However, successful implementations around the world show that pedestrianization contributes to increased retail activity. Pedestrianization of Istiklal Caddesi in Istanbul demonstrated that limiting vehicle access and creating attractive environments for consumers could improve business activity. Table 2 presents a summary of potential economic benefit categories that should be considered when evaluating walking improvements (Litman, 2003). Litman highlights the importance of wider impacts when thinking about economic benefits of pedestrianization. Impacts on Businesses This study aimed to focus more specifically on impacts of pedestrianization on businesses. A brief literature review reveals many studies that suggest positive impacts of similar projects on local businesses: • Sermons and Seredich (2001) identifies benefits or improving conditions for non-motorized street users at the vicinity of urban small business: 1. Economic Revitalization and Property Values – Traffic calming can increase residential and commercial property values, which attracts wealthier residents to the area (gentrification) and can increase retail sales and bring economic revitalization to a commercial corridor. 2. Attractiveness and Safety – Traffic calming creates more attractive environments, reduces auto speed, and increases safety for pedestrians, bicyclists, drivers, and other users of the street, which is good for business. 3. Sales and Attracting Customers – Traffic calming encourages local residents to buy in their own neighborhoods, and also attracts customers from a wider area due to reduced travel time, hassle, and cost. Traffic calming can also help Table 2 Potential Economic Benefits of improving walkability (Litman, 2003) Accesbility Consumer cost savings Public cost savings Efficient land use Livability provides mobility options, particularly for people who are transportation disadvantaged. turnovers are also transferred to landlords partially, in the form of higher market rents. It is also important to note that some reduction on turnovers can be observed in the initial years of implementation during the transition period. (Hass-Klau,1993) provides consumer transportation cost savings reduced external costs - substitutes for vehicle travel and reduces negative impacts helps reduce the amount of land used for roadway and parking facilities, and helps create more accessible, clustered land use improves the local environment Public fitness and health provides physical exercise to people who are otherwise sedentary Economic development makes commercial areas more attractive and shifts consumer expenditures to goods that provide more regional economic activity and employment people live less car-dependent lifestyles, which will increase the amount of discretionary income they can spend on things other than transportation. 4. Parking – Most businesses are concerned about the quality and quantity of customer parking and access for delivery trucks. However, too large a supply of subsidized, on-street parking can harm businesses. 5. Impact on Employees – Poor bicycle, pedestrian, and transit conditions can harm businesses by losing worker productivity and time to gridlock, and by impairing employee recruitment. Conversely, improved transportation facilities can provide more convenience for employees. 6. Construction and Costs – Traffic calming projects often require only minimal “down time” for construction, and most do not require any investment from business owners. • Shops within pedestrian areas are more successful than those outside, as pedestrianized areas are more attractive for shoppers. Increased • A survey of more than 100 cities around the world, concerning their pedestrianization schemes, revealed environmental improvement closely related to the removal of traffic. The survey also showed that 49% of all the pedestrian areas developed experienced an upward trend in retail turnover, while only 18% experienced a decrease, and %25 stayed stable (OECD 1978). Cities in Austria, Germany and Scandinavia experienced increase in turnover of more than 60% (OECD, 1978). These studies show that successful pedestrianization projects create better environments for people. These improvements attract more shoppers, and increase economic productivity and employment in pedestrianized areas. Higher turnovers are also reflected in higher market rents. Individual perceptions play a vital role in achieving these benefits. This study investigates the perceived benefits and disadvantages of pedestrianizing Historic Peninsula. Interviews were conducted with businesses in the area based on expected benefits as suggested by the literature and local administration. 3.2 Impacts on Air Quality Environmental impacts of emissions from motorized vehicles in the Historic Peninsula can be analyzed in two main categories: (i) health impacts, and (ii) impacts on urban spaces and historical monuments. Negative impacts are especially significant in urban areas with high levels of traffic congestion. Main pollutants from motor vehicles include sulphur oxides (SOx), carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOC), lead, particulate matter (PM), and ozone (O3). Impacts of air quality on health Table 3 presents the types of health effects experienced by the most common vehicular pollutants at elevated levels. Table 3 Health effects of pollutants at very high levels Sulphur Dioxide Respiratory diseases Nitrogen Oxides Eye and respiratory diseases Particulate Matter Cancer, heart diseases, respiratory diseases, increases in rate of stillbirths Carbon Monoxide Combines with hemoglobin and diminishes hemoglobin's oxygen-carrying capacity, death Ozone Respiratory diseases, eye and nose irritation, asthma, decrease immunity Volatile Organic Compounds Eye, nose and throat irritation, headaches, nausea, vomiting, liver damage, kidney damage, central nervous system damage Pedestrianization projects are expected to reduce vehicle traffic, and thus reduce pollution levels. However, Istanbul and particularly the study area lacks sufficient data on pollutants listed above to quantify air quality impacts on health. Currently, there is a single Air Quality Measurement Station in Aksaray. This station is not representative of pedestrianized streets, as it is located in an area where there is continuous traffic flow. In other words, if pedestrianization of streets were successful in improving air quality, it would not be reflected on measured pollution levels. Indeed, quantitative comparisons between 2009 and 2012 pollution levels for (SO2, NO2, CO, PM10) show no significant changes. Impacts of air quality on cultural heritage stocks Corrosion is another important impact of air pollution for the Historical Peninsula, as it is home to rich historical sites. A decade ago, SO2 was considered one of the most important air quality parameters on the corrosion of cultural heritage stocks. Significant increases in the levels of nitrogen compounds, ozone and fine particulate matter in the ambient air have been associated with the increasing automobile traffic; however, a decreasing trend in SO2 levels has been observed in most parts of Europe and Türkiye. Scholars continue to study impacts of vehicular emissions on historical stocks.
  • 9. Pedestrianizing Istanbul's Historic Peninsula 15 Ferhat Karaca Associate Professor, Fatih University "Fatih University Air Quality Research Group completed the most comprehensive study on the air quality for the Historic Peninsula, and results were published in 2013. Overall, observed levels of pollutants do not pose significant risks for human health. At the local level, traffic density raises pollutant levels, creating hotspots. European Commission or Environmental Protection Agency does not have threshold levels for ensuring protection of heritage stock. Therefore, it is hard to reach conclusions on risk levels for the historical heritage stock in the historical peninsula. It could be said, however, that observed pollutant levels point to high-risk levels. It is known for a fact that high NOx, SOx, and PM levels might lead to corrosion of heritage stock. Traffic levels contribute significantly to higher levels of pollution. Therefore better traffic planning in the area, and transforming the historic peninsula into a traffic free region is an important step towards protection and conservation of heritage stock in the Historic Peninsula." Pınar Mengüç Professor, Özyeğin University "It is likely that climate change will become the biggest environmental problem in the history of mankind. There have been changes in the climate before, when the entire history of earth is studied. However, none of these resulted from human activity and no significant changes were observed during the 10,000-year history of humankind. High concentrations of greenhouse gases (GHGs), like water vapor, carbon dioxide, and methane absorb energy, cause changes in Earth’s energy balance in the atmosphere and triggers climate change effects. Fossil fuels used in transportation, building, and industries are the major cause of increased concentration of GHGs in the atmosphere. Burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of particulate matter. 'Particles less than 10 micrometers in diameter (PM10) pose a health concern because they can be inhaled into and accumulate in the respiratory system. Particles less than 2.5 micrometers in diameter (PM2.5) are referred to as "fine" particles and are believed to pose the greatest health risks. Because of their small size, fine particles can lodge deeply into the lungs.' (US EPA) A recent article published by Lancet showed that surge in car use in India and China is responsible for millions of premature deaths. Inevitably, all metropolises including Istanbul are faced with the same threat. Measurements of particulate matter emissions are important for the development of urban transportation policies. These measurements will also help quantify economic consequences of health impacts. Furthermore, high particulate matter emissions create significant corrosion risks for historical stocks, which lead to further economic loss. Fatih University conducted a comprehensive study in the Historic Peninsula for measuring SO2, NO2, CO, and PM10 levels. Details of this study and its finding are presented in this report. We have developed tools to measure characteristics for particulates of size 100 nanometers and below. Fatih University and Özyeğin University have partnered to take this research further. Through our partnership with EMBARQ Turkiye, it is our hope that our work will have wider benefits for the Historic Peninsula and Istanbul. " Dr. Ferhat Karaca’s thesis, “Mapping the corrosion impact of air pollution on the Historical Peninsula of İstanbul” is the most comprehensive study conducted so far for evaluating the corrosion levels related to air quality and the seasonal pollutant (NO2, SO2, and O3) exposure levels over 50 monitoring stations distributed on the historical peninsula of Istanbul. Exposure levels of SO2, NO2, and O3 pollutants in the Historical Peninsula atmosphere were measured using passive samplers between October 2008 and August 2009, seasonal and spatial distribution characteristics of the pollutants over the region were evaluated, and high-resolution corrosion impact maps were obtained on the Historical Peninsula of Istanbul. Findings were published, and below is a summary of study results (Karaca, 2013): • The SO2 exposure levels in this study indicate a moderate level of risk for the peninsula. There is a SO2 hotspot situated between the two largest university hospitals (Cerrahpasa and Capa). A very busy road (E-5) passes through the area and it is most probable that the SO2 exposure levels around these places have increased as a result of daytime traffic activities. • Both NO2 and SO2 have been attributed to traffic related distribution, and therefore their exposure distribution maps have similarities. There are two hotspots for NO2 exposure during the spring period: Firstly, the road zone between the Ataturk bridge and Eminonu, and secondly, an area centered on the Topkapi junction on the 10. Yil Avenue (Motorway). Both of these areas are combined and it is seen that the NO2 exposure was also stretched from Topkapi Junction into Fatih District (the midland of the peninsula) through Turgut Ozal and Adnan Menderes Avenues during winter. • Ozone is a secondary pollutant. The tip of the peninsula is identified as a hot-spot. The PM10 values during July and August 2010 were significantly higher than the average value, and no significant relation was observed with the other pollutants during these two months. Findings above suggest that high NO2 and SO2 levels are attributed to high levels of congestion. Corrosion effects are observed in the identified areas for high NO2 and SO2 levels. Pedestrianization projects are expected to reduce these corrosion effects by reducing traffic in the area. In assessment of net impacts of pedestrianization, air quality measurements before and after project implementation at pedestrianized sites are required for comparisons. Unfortunately, these data were not available and net benefits of completed pedestrianization projects on corrosion cannot be quantified at this stage. Quantifying air quality improvements Quantifying air quality improvements resulting from pedestrianization is not plausible at this stage due to large data requirements. Therefore, it is hard to put a number on the achieved benefits on health and historical stock. However, it was possible to capture some of the perceived benefits from improved air quality through the survey. Further details on the survey are presented in Section 4. Conversations with scholars in Türkiye showed significant level of interest in analyzing air quality improvements in the Historic Peninsula. Yet, lack of data hinders researchers. It is important for local administrations to make the data publicly available to promote research as quantified benefits from projects will make it much easier to draw investments to fund similar projects.
  • 10. Pedestrianizing Istanbul's Historic Peninsula SECTION 4 perceptıon survey Individual perceptions play a vital role in identifying the full benefits of pedestrianization. This study investigates the perceived benefits and disadvantages of pedestrianization projects in the Historic Peninsula between 2010 and 2012. 4.1 Methodology While it has not possible to carry out a complete economic impact analysis within the scope of this project, this study focused on four main regions in the Historic Peninsula and aimed to understand the perceived effects of pedestrianization on the local community. Inputs from academicians (Istanbul Technical University) and the EMBARQ Network’s experts were used in designing the survey. Project Planning and Technical Works Units at the Fatih Municipality provided pedestrianization project drawings, which were used to define the survey area in our study. Comparative data on function changes before and after the project completion were not available. Therefore, it was not possible to assess the degree of function change in the pedestrianized regions. However old and new photographs taken at the area were also provided for comparison. Business owners and managers in the area were surveyed to assess satisfaction levels. The rational behind the decision to target businesses are three-fold: (i) businesses rather than residential buildings dominate pedestrianized regions and therefore constitute the largest stakeholder group, (ii) shoppers are also a large stakholder group, however most are local and foreign tourists who are not regular visitors, (iii) achieving economic benefits from pedestrianization is only possible if businesses perceive benefits of these projects and replicate in new environment. Survey Area Pedestrianization projects were implemented at four main regions of the Historical Peninsula: Üst Laleli, Alt Laleli, HocapaşaSirkeci and Eminönü-Tahtakale. 256 streets and roads have been pedestrianized. Sample areas from each of these regions were selected to conduct the survey as presented in Table 4. 17

The surveyors were selected from university students and they attended a one-day long briefing meeting prior to field visits. Inputs from experts in the field Meetings were held with Dr. Ferhan Gezici and Prof. Dr. Handan Türkoğlu, Research Assistant Eda Beyazıt from Istanbul Technical University to receive their inputs and feedback in defining a methodology for assessing economic impacts of pedestrianization through the survey. Their recommendations included the following: • Occupancy rates and workforce changes, • Changes in sales volumes, • Changes in transport mode choice, • Streets where main arterial roads cross with bystreets, and • Conducting surveys in four phases: prior to project, shortly after project declaration, shortly after project completion, long after (10-20 years) project completion. Meetings were held with Laleli Businessmen's Association (LASIAD) as part of survey design, to receive some insight about concerns and perceptions of businesses in the area. LASIAD worked very Pedestrianizing Istanbul's Historic Peninsula 19 closely with Fatih Municipality during renovation of sidewalks and pavements as part of pedestrianization works. LASIAD General Secretary Şerafettin Yüzüak emphasized how much they value rehabilitation efforts. In this line, LASIAD convinced the municipality to use natural granite instead of lock paving stones for 12 streets and paid for the additional costs. 4.2 Main Findings This section presents an overview of the findings of the perception survey conducted on December 4th and 5th, 2012. The analyses are based on responses from 423 shops, all of which are located on pedestrianized streets. Findings from the recent report by GEHL Architects are also used to support survey results where relevant. Below is an overview of the analysis section: Overview of businesses section presents characteristics of the shops surveyed and provides some background on the sample, Attitudes towards pedestrianization section provides a summary of current and past attitudes toward pedestrianization, as well as expectations for the future, Changes in sales section aims to provide insights on observed and expected changes in sales volumes, customer base, and income, Property values section presents locals’ perception on changes in property values as a result of pedestrianization, Travel to work looks at transport modal shares, Parking presents perceptions on available car parking alternatives, Urban environment section covers respondents’ perceptions on observed changes in the urban environment following the completion of the pedestrianization project. 4.2.1 Overview of businesses Location Table 5 displays the representation of each area as a percentage of shops surveyed in the area. For the analysis, overall results are presented, and unique patterns for different areas are highlighted where relevant. 2010). Pedestrianization and other supporting projects should aim to increase the diversity in the area in the future. Table 5 Representation of areas in the region Newcomers in the area 17% of the respondents reported that they have moved to the area within the past five years. Among these newcomers, 52% noted that they have moved to the area because they believe there are better business opportunities, and 20% said that they wanted to attract more tourists. While many shop owners aim to attract tourists, GEHL reported that tourists tend to collect monuments from their checklist and neglect the remaining splendors of the city. Creating a better environment for tourists to walk around the shops promoting social interaction will help these shops to attract more tourists. Area % of shops surveyed in the sample Eminönü 15% Hocapaşa 28% Alt Laleli 37% Üst Laleli 20% Shop owners and employees Only 32% of the respondents were shop owners, the rest were employees (52%) and managers (16%). It is important to take such low percentage in consideration especially when analyzing the responses to questions on expected and/or observed increases in income levels. Gender diversity Males dominate the sample population by 93%. This lack of diversity is also reflected in the GEHL Report analyzing the Historic Peninsula as a whole (GEHL Business types: Domination of wholesales traders Business type distributions are presented in Figure 2. Only 26% of the surveyed shops were solely involved in retail. Such distribution might not be favorable for a pedestrianized area, as wholesale traders and their customers will have higher delivery and logistics needs. Currently, most wholesale traders are located in Eminönü and Alt Laleli area, while retailers dominate Hocapaşa. Üst Laleli has an equal distribution of retail and wholesale traders. It is expected that the new pedestrianized area will attract more retail traders.

  • 12. 20 Pedestrianizing Istanbul's Historic Peninsula 4.2.2 Attitudes Toward Pedestrianization It is important to understand what locals think about the project to ensure its success. Their views, suggestions, and concerns are valuable for local authorities to improve current conditions and get buy-in of businesses in the area. High acceptance and satisfaction levels are also valuable to get support for future pedestrianization projects. Q15 ask respondents their views on pedestrianization after its completion: • 78% of respondents were pleased or very pleased with the results of the project, • 19% were not pleased or not pleased at all. Changes in perception Q14 and Q15 ask respondents if they supported the pedestrianization at the beginning, and if they are satisfied with the results at the end. Figure 4 presents changes in perception through responses to Q14 and Q15: • 40% of the respondents supported the project at the beginning, and 90% of those supporters were happy with the results; • 62% of the people who did not have an opinion at the beginning were happy with the results at the end; • 23% of the people who were against the project at the beginning were happy with the results at the end.

Such high percentage is reflection of high satisfaction about the current implementation. Suggestions to improve current conditions to make deliveries more convenient include changes to hours of operation and provision of special permits to shop owners. 58% of respondents are happy with the hours, however 41% are not. 4.2.3 Changes in Sales Pedestrianization projects often aim to increase economic activity in pedestrianized areas by attracting more shoppers. However, it is often very challenging to measure the net effect of pedestrianization on net sales volumes due to high accurate data requirements. This survey aimed to measure perceptions of respondents with regards to observed and expected changes in sales volumes, rather than attempting to measure the net effect based on sales figures. Q18 asks if shops in the area expect their sales to increase or decrease after pedestrianization: • 56% expect sales to go up • 16% expect a decrease in the sales volume. Figure 3 Satisfaction with pedestrianisation after completion I am not pleased at all I am very pleased 5% 7% I am not pleased 14% I don't know 3% I am pleased 71% Expectations Concerns Better landscape planning High support for other pedestrianization projects Q27 asks whether the respondents support future pedestrianization projects in the area. 83% said that Problems with deliveries Q14 asks for more details on expected and observed changes in staff needs, annual income, and number of customers, which might be reflective of perceptions on economic activity (Table 7): • Most respondents reported that they did not observe any changes and are not expecting any change in the future as a result of pedestrianization. • 25% expects increases in their annual income, and 39% expects an increased customer numbers. • A significant percentage of respondents are concerned about decreases in their income and customer numbers. Noise Reduction Decrease in sales volume Increased Sales Problems with enforcement Concerns and expectations Q13 asks about concerns and expectations about pedestrianization. Table 6 presents a list of common concerns and expectations reported by 125 respondents: Table 6 Common concerns and expectations reported by 125 respondents Problems with deliveries Q9 asks respondents if logistics and delivery problems became more of an issue after pedestrianization. This is important to understand potential impacts of pedestrianization on businesses: • 38% report that they are having more difficulty than before, • 61% says that there were no additional burdens in terms of logistics needs.

Müslüm Deveci and Murat Ergin underlined the fact that there are numerous factors influencing the real estate market, and emphasized the challenge in understanding the net impact of pedestrianization on prices. Their general opinion was that the pedestrianization project had a positive impact on the market, increasing both rental and property values. Real estate sales price changes between 2010 and 2012 in the area that covers both pedestrianized and non-pedestrianized streets are presented in Table 8 to give an idea of the observed changes in the market. Table 8 Changes in real estate sales prices Pedestrianization Region 2010-2012 Real Estate Sales Price Change (%) Alt Laleli Region 15% 4.2.4 Changes in Real Estate Value Nişanca Bostanı Street 14.50% As pedestrianization increases the attractiveness of the urban areas and creates high quality environment, it is expected that property values will increase. However, the net effect of pedestrianization on property values is often very hard to measure since there are a lot of external parameters that affect changes in property values. Furthermore, academicians consulted suggested that it might take up to 10 years for researchers to observe increases in property values after project completion. This survey therefore aimed to understand perceived and expected changes in property values. Pehlivan Street 14.50% Şair Haşmet Street 15% Hocapaşa (Average) 18% Sultanahmet (Average) 22% In response to Q13, which asks expectations on property values after pedestrianization, 21% selected ‘Increase in property values’. Q22 and Q23 ask about observed and expected
  • 13. 22 Pedestrianizing Istanbul's Historic Peninsula Pedestrianizing Istanbul's Historic Peninsula 23 changes in property values in more detail. Table 8 shows the observed and expected changes in property values reported in response to Q22 and Q23. While most respondents did not observe an increase in rental or property values, 43% and 39% respectively are expecting to see a change in the future. Table 9 Expected and Observed Changes in Property Values Increase No Change Decrease Observed change in rental values 25% 74% 1% Expected change in rental values 43% 52% 5% Observed change in property values 27% 71% 2% Expected change in property values 39% 55% 6% is still important to understand the current situation to analyze modal shifts in the future. The current shares reported by survey respondents are presented in Figure 5. The current share of public transportation is already high at 65%. The expectation is to see more people using public transport and walking as their main mode of travel in their commutes to work. High share of public transport in Eminönü and Hocapaşa Walking’s share is relatively high at 14% in the Alt Laleli area. Share of public transport is 75% both for Eminönü and Hocapaşa, which reflects the strong public transport network serviced by ferries, buses and tram. Private cars have a significant modal share in commutes to work everyday at 26%. Most used public transport mode: Buses Among public transport users, buses are the most popular choice with 51%, followed by the tram at 36%. Commuter train services and ferry services both have share of 5% among public transportation modes. 4.2.5 Travel to Work It is important to understand the modal distribution before and after the pedestrianization. The survey was conducted only three months after the pedestrianization of these streets were completed, and did not ask the respondents about their transport modes before project implementation. While we currently cannot measure any shifts that did occur, it Of the 108 respondents who indicated that they commute to work by car, 93 reported that they use car parks, and seven of them park their car on the roadside. It is however important to note that current car parks are sometimes located on the roadside 100% Walking 80% Private Car Public Transport 60% 40% 20% Eminönü Hocapaşa Üst Laleli Additional two questions were included in the survey to understand perceptions of availability of parking space before and after pedestrianization: • The majority of the respondents noted that available parking spaces are adequate (56%), followed by the 42% who indicated that the available parking spaces are lower in numbers than the demand and there is a need for more car parks. • The majority reported that there was no change in the availability of parking spaces after pedestrianization (83%). • 13% of the 176 people who reported that the parking spaces were not satisfactory prior to pedestrianization thought that the number of parking spaces decreased even further. • 14% of the 236 people who reported that the parking spaces were adequate thought that the number of parking spaces increased since the pedestrianization. 4.2.5 Parking Figure 5 Method of Travel to Work Alt Laleli and inappropriate next to existing monuments as suggested in the report by GEHL. Total Respondents' recommendations The survey asks the respondents if they have any recommendations for additional parking spaces. Among the 45 recommendations, mostly from car users, some highlights include: • Prices are too high, there might be a lower fee scheme for local shops; • More multi-storey car parks will be beneficial, • Building car parks below ground under existing buildings might be a good option; • Specific locations named include: Kumkapı, Aksaray, Beyazıt, Sarayburnu, near Sirkeci Train Station. 4.2.6 Urban Environment Pedestrianization projects aim to improve streetscapes, reduce noise levels, and improve air quality. All of these improvements will create better and healthier living environment and consequently better experiences for visitors and locals. It is therefore important to understand perceptions on above noted components to assess the success of the project. In this line, the survey asked respondents some questions on their perceptions of the changes in noise levels, air quality, and landscape improvement/ planning. Noise Levels 62% of the respondents thought that noise levels were very high in the area due to motorized traffic. 91% of these people who were concerned about the noise levels reported a decrease as a result of pedestrianization. This is a very positive outcome of the project reflecting its success in reducing noise levels. Air Quality 34% of the respondents thought that air quality, especially emissions from cars were serious issues for the area. 86% of these people who were concerned about emissions and air quality reported better air quality as a result of pedestrianization. Clean Streets Clean streets improve the atmosphere and the image of a road. 33% of respondents were concerned about their streets not being clean enough. 85% of these people who were concerned reported an improvement after pedestrianization. Resting Options GEHL reported an extensive lack of resting options in terms of public benches along the streets. 58% of respondents share this view and report that there is a lack of public benches in the area. However, 85% of these respondents said that there was no improvement in the availability after pedestrianization. This highlights a key area for improvement. Pedestrian Experience Pedestrians experience several challenges on the streets in the Historic Peninsula due to limited availability of space for walking. 61% of respondents were concerned about such challenges prior to pedestrianization, and 86% of them reported improvements achieved afterwards. Street Sellers 21% of the surveyed shops were concerned about the growth in the number of individuals who tout for trade in the Historic Peninsula. Some of these traders might cause annoyance to the public, and obstruct footpaths. Most respondents believe that municipality should be stricter with street sellers.

These will be valuable for local authorities to get a grasp on current concerns of the locals and their expectations. • 78% of respondents said that they were pleased or very pleased with the pedestrianization. • 83% said that they would support pedestrianization projects in other areas. • Locals are mostly optimistic about the future: 56% expect sales to increase, 39% expect customer volumes to increase, 25% expect annual income levels to increase, 39% expects property values to increase. • Current share of public transportation is already high at 65%. It is the most popular mode in commutes to work. The expectation is to see more people shifting to public transportation or walking from private vehicles. • Respondents who were concerned about noise levels and air quality reported significant improvements. The locals were expecting better landscape planning as part of the pedestrianization project (e.g. more public benches, plants and flowers, infrastructure improvements for pavements, etc.). However, there were no changes on pedestrianized streets apart from physical barriers to prevent motor vehicles from penetrating. Streetscapes should be improved on pedestrianized streets. There are significant concerns over the imposed difficulties with deliveries to the shops. Further investigations are required to understand business concerns in the area, and whether changes to hours or special permit provisions are required to improve perceptions. These concerns might decline over time, as businesses are more familiar with new requirements and adapt their business operations accordingly. Decline in sales volumes is another common concern. Respondents are worried that restricted vehicle access in their streets might discourage their customers. It is therefore important to improve the streetscape to attract customers to these streets. 42% of respondents believe that there is a need for increased parking spaces to meet the demand. Furthermore, GEHL Architects report that current car parks are already located on the roadside and inappropriate next to monuments. It is therefore important to improve public transportation services in the area. If more people shift to alternative modes, demand for car parks will decrease. This will also improve streetscapes. Street sellers are another concern as there is an increase in their numbers with pedestrianization. Regulations and associated increased enforcements to reduce street sellers should be reviewed to ensure a better environment both for locals and visitors.
