2. Smart City
Creation and connection of human capital, social capital and Information and Communication Technology (ICT) infrastructure in order to generate greater and more sustainable economic development and a higher quality of life

3. Smart Cities can be identified along six axes:
Smart People
Smart Environment
Smart Mobility
Smart Economy
Smart Living
Smart Governance

4. Mobility: Traditional Approach
TRAFFIC:
Increase the capacity of the underlying
infrastructure by building more roads and bridges
Increase the number of vehicles providing
transportation services, such as public
buses and trains
Crucial element of daily operations in any community or city

5. Mobility: Smarter Traffic
Current city transportation systems and associated infrastructures are strained
Smarter Traffic
integrates technology and intelligence into the city transportation infrastructure

6. Objectives for a Smarter Traffic solution
Predict demand and optimize capacity,
assets and infrastructure
Improve the end-to-end experience for
travelers
Increase operational efficiency while
reducing enviromental impact
Ensure safety and security

7. Smartphone Traffic Application
MOTIVATION
Users know the traffic situation in real time
They choose the best route
Advantage for each driver
Global congestion reduction

8. Smartphone Traffic Application
INITIAL REQUIREMENTS
City cameras
Built a central system (with all the cameras info)

9. Smartphone Traffic Application
OPERATION
Mode 1
Cameras traffic info +
City map
Color code on every street depending on the level of congestion

10. Smartphone Traffic Application
OPERATION
Mode 2
Cameras traffic info +
Voice interaction
Interactive traffic application based on user preferences

11. Smartphone Traffic Application
OPERATION
Mode 2
Say where you want to go
Say your driving preferences
The system tells you the best route
Fastest route
Cheapest route
Passing through X …

12. Smartphone Traffic Application
- Android (most common mobile OS)
- Google Speech Api (natural voice input)
- Google (or an alternative) maps service
for showing routes

13. Intelligent traffic lights management system
Design of an Intelligent traffic lights management system,using the information provided from video cameras

14. Traditional traffic lights
•They just show information
•That information is previously programmed and implemented on them
Nowadays, it doesn’t make sense, an intelligent system will be more efficient

15. How can we do this? •Using video cameras
•They will provide important information:
–Traffic density
–Type of vehicle
–Speed

16. What we do with that information?
•The information is sent to a central system
•The system will analyze it, to synchronize the traffic lights in the most efficient way

17. Technological requirements
We will need an embedded system on each traffic light, consisting on:
Video camera: able to recognize and track objects and different parameters of the environment
Micro-controller: capable of analyze the information achieved by the camera, and send it to central system

18. Benefits With this system we will have some benefits: - Money on gas
- Traffic jam
- Pollution
+ Happiness

19. Improving the central system
-With the central system we will solve most of the traffic problems
-There are some special and unpredicted events that we can’t handle
The central system will consider each traffic light as an intelligent agent, able to make their own choices based on the iformation they get.

20. Unpredicted increase of road’s traffic density
Due to special events
The system can’t predict that
The traffic light will increase the time of the green light
The other traffic lights will be fixed

21. Emergency cases such as the passing of high priority vehicles
If they don’t know the destination…
If they know the destination…
The traffic light will detect them
The green light will be turned on
The other traffic lights will be fixed to avoid accidents
The vehicle will communicate with the central system
The system will tell the faster way
All the traffic lights on the way will turn on the green light

22. Traffic lights Warning - Passing Emergency Vehicles
Normally people know that there is an emergency vehicle passing when they see the vehicle or hear the alarm
With the central system, the traffic lights in the way that the emergency vehicle is passing will turn to flash
To warn the drivers to reduce speed or change into the same lane if necessary
People can know the emergency situation in advance to prepare

23. Brightness control of traffic lights
Use cameras to create a system that allows to decrease the brightness of traffic lights if there are no cars or pedestrians and increase it in the opposite situation with the aim to save energy

24. Benefits We will avoid traffic jams caused by unpredicted events.
The emergency vehicles will arrive faster, so we can save some lives.
We will prevent having accidents due to emergency vehicles passing with red lights.
We will save energy when the traffic lights are not needed.
