  1. Erasmus Intensive Program Lahti 2014 Smart City Francesca De Gregorio Simin Luo Guillermo Vidal Pombo Stephan Leibelt Nerea Gonz lez

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

  4. Mobility: Traditional Approach TRAFFIC: Crucial element of daily operations in any community or city 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

  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 Color code on every street depending on the level of congestion Cameras traffic info + City map

  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 Fastest route Cheapest route Passing through X The system tells you the best route

  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 roads 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 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 The green light will be turned on The other traffic lights will be fixed to avoid accidents

  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.
