3. 1.1Traffic impact assessment (TIA)
• Is a powerful tool for engineers and planners to determine the possible
effects of a project on the transportation and traffic system.
• It is applied only to the direct impact area and countermeasures for
potential negative impacts are specific for the development
• TIA as a useful tool for local governments, especially for managing traffic
and in planning their respective transportation systems
• The purpose of (TIA) is to assess the impacts of development on the
transport network and identify reasonable solutions, applicable to the
Tasmanian experience, to address these impacts
1.2 Why TIA Is Important
• The concept of sustainable development recognizes the impacts of motor
vehicle use on the environment and the desirability of increasing the use of
public transport.
• This recognition extends to both the natural and built environment.
• Most developments attract more private transport movements rather than
public. It is, therefore, necessary to address the impact of motor vehicles
and road traffic effects on the environment

and road traffic effects on the environment

4. 1.3 Trip generation
• Trip generation is normally the first step in estimating future travel
demand.
• It is used to estimate the number of trips generated and attracted by each
unit area.
• The characteristics of trips generated by typical land uses are estimated
using established trip generation rates. They are normally expressed per
unit of related factors such as trips per dwelling units, per Gross Floor
Area, per students, etc….
• The main source for these rates is the trip rates developed within the KAU
traffic model.
1.4 Methods for Estimating Trips Generated
• The use of standard rates used by local and regional planning agencies,
which are most often based on previous projects.
• Standards from similar locations, built by the same developer or company.
• Surveys of sites in comparable areas.
• Literature on rates in journals, such as the ITE Journal.
• Trip Generation Rates from the Institute of Transportation Engineers’
publication, Trip Generation.

• January, 2013
• King Abdul-Aziz University (KAU) is one of the largest universities in the
Kingdom of Saudi Arabia
• It's located close to the center of Jeddah in close proximity to one of the
major freeway of the city, Al Haramain highway
• It’s located on the North West area of the university adjacent to the old
hospital in the KAU University
• It is located close to three access gates of the KAU namely Gate 1, Gate 2,
and Gate 3
• The KAUH area is approximately 235,000 sqm and
comprises:
1. Hospital
2. Clinic
3. Education
4. Research
5. Administration facilities

6. 2.2 Site Location of KAUH Project

7. 2.3 Aim of the Study
The purpose of the TIS is:
• Examine the implications of the construction of KAUH on the surrounding
road network
• Analyze the internal traffic elements of this development including the
access/egress points and car parking availability.
2.4 Traffic Study Methodology for KAUH
• Collect and review available data sources.
• Assess current and future Level of Service of roads and junctions, taking
into account future land-uses and background traffic growth.
• Estimate the amount of traffic generated
• Estimate the future volumes of traffic on roads and junctions
• Establish the impact on the road links and junctions and assess the resulting
Level of Service.
• Compare the “With Project” and “Without Project”.
• Assess the adequacy of the drop-off and car parking supply proposed by the
project.
• Identify the types of improvements required in order to minimize the
adverse traffic impact of the proposed development and improve traffic
circulation and conditions within the area of influence.

8. 2.5 Analyzing

parking structures.

J6 Proposed Improvements

13. 2.7 Conclusion
• The operation performance for six intersections within the study area of
the KAUH has been analyzed where five of them are expected to be
operated at un-acceptable LOSs.
• For enhancing the operation performance at J1 (Roundabout), physical
improvements will be required as follows:
 Adding a slip Right turn lane for E-N bound-Traffic;
 Adding a slip left turn lane for W-N Bound-Traffic; and
 Increasing the number of lanes for the north leg from two to three lanes.
• For enhancing the operation performance at the un-signalized intersections
(J3, 4, 5, 6), the control type should be changed from priority to
signalized type is required.
• An efficient way finding system for the new hospital should be
implemented on the KAU external road network in order to ensure that
the hospital commuters will use the shortest path identified by the model
through Gate 1, Gate 2 and Gate 3.
• The drop-off spaces required for the commuters are estimated. In
addition, the total parking demand estimated for different land uses
accounts for 3374 Parking Places

14. 3 Study Area
