basically, are their inhabitants. Governments need to listen to them if they want to stay on top,
keep (attracting) leading companies and want to avoid a brain drain.

their city. weather data to information on population, employment, housing, road conditions, mailboxes,
traffic, transportation, pollution levels, markets, events, waste disposal, management, education,

Open Data platforms are dealing with enormous numbers of data from different architectural
environments where it was often stored in a proprietary form. Such public initiatives therefore pose
challenges in scalable data storage, data traceability, data quality, data interoperability and data
visualization. Big Data technology can handle all these requirements.
Increasingly, city governments are beginning to understand the opportunities of Open Data
platforms and how they are an expert example of how ‘more eyes are better’ when it comes to adding
value to data.
Amsterdam’s urban EcoMap collects data from a number of different sensors and sources, and makes
it available for the development of all kinds of mashups and other applications. The UK’s government

Putting a stop
to Carmageddon
Smart Cities are not only driven by ‘the People’ of course. City authorities need to be their main
champions and leaders. They are the ones that can enhance the efficiency of city management and
operation by means of intelligent technology.
City government’s smart efforts come in all shapes and colors: from smart grid projects for
optimizing energy control to reducing congestion (with traffic insights delivered in real-
time information to the citizens) and managing pollution with sensors. They can utilize Big
Data tools to generate predictions for storm tracking purposes. They could optimize their
communication with web applications - like SeeClickFix - to empower citizens with a simple
channel to reach their government about non-essential issues. They could - like Chicago - use
audio sensors attached to rooftops and telephone poles that can detect when a gun is fired and
pinpoint the location, enabling police to respond to serious crimes without the need for citizen
intervention.
Provided all its stakeholders are willing to open up their data to one another, the possibilities for
improving a city are endless. This chapter and the next will afford some deeper insights into two
of the most popular types of Smart City enablers: smart traffic and smart energy.

make it better prepared to address emergencies such as severe storms, earthquakes, large solar
flares or even terrorist attacks.
According to the New York Independent System Operator, its new smart grid technology
has the ability to prevent a blackout like the one in August 2003, which left 55 million people
across eight U.S. states without power. The blackout was estimated to have cost $10 billion
in economic impact. Big Data and Smart Grids can make sure that such financial disasters

The OECD reports that smart meter information may encourage people to reduce domestic

will reduce emissions by 48%. A recent trial of smart meters by Ireland’s Commission for Energy
Regulation in 10,000 homes and businesses found that 82% of residential customers made a
change in their energy use. The UK’s Energy Saving Trust calculates that the rollout of smart
meters from 2014 could save UK customers £7.3bn in fuel bills over 20 years. Smart meters work!

14. 07 Bright Cities, Big Data
Since Big Data is all about continual change and speedy adaptation, these solutions need to be
dynamic and simultaneously update as the data changes. They allow users to identify patterns,
trends and relationships without having to run the data through complex statistical models.
Setting a strategy
Realizing what Big Data and Open Data can mean to smarten up your city is one thing, the other is,
of course, making sure that your organization is ready for the sea of change that this will bring about.
I’m not only talking about technology here, I’m talking about fostering a mindset change in your
government’s management.
“ Every truth passes through three stages before it is recognized. In the first, it is
ridiculed. In the second, it is opposed. In the third, it is regarded as self-evident.”
Arthur Schopenhauer
Clearly city authorities are not always riddled with data-savvy civil servants and governors. People
are their highest priority, and they should be. But people and IT do not rule each other out. On the
contrary, Big Data technology can help you get to know them through and through and serve them

structure. They master data management platforms as well as predictive analytics tools. They are the
ones that have the skills to put their shoulders underneath the Smart City.
In the near future, Big Data and Smart Cities will become the norm. If your city government
does not adapt its technological architecture to manage this upcoming change and embrace its
possibilitieswith both hands, it will be in trouble when this transition takes place. Make sure that you
are up for it. Start now.
Remember, we are only at the beginning of the Smart Cities era. Some of us are even dreaming
about the Internet of Things, which would give our cities a real voice. This is what will happen
when all everyday physical objects will be connected to the Internet (by means of all kinds of sensor
technologies like RFID) and will be able to identify themselves to other devices. There will be 25 billion
devices connected to the Internet by 2015 and 50 billion by 2020. Just imagine how smart our cities
would become if all of these could talk to each other.
According to Pike Research, in the present decade, cities around
the world will invest $108 billion in Smart City infrastructure.
Make sure you are one of them.
