The city
São Paulo is the largest city in Brazil and is the world’s 7th largest metropolitan area. With a population of 11,105,249 residents within an area of 1,523 km2, the city is the largest city in the Southern hemisphere in terms of population. The Greater São Paulo, on the other hand, consists of 39 municipalities, including the capital, São Paulo, with around 27,640,577 population spread over 23,062 km2. Greater São Paulo has over 6.2 million cars, 4 million of them in São Paulo city. São Paulo is a heavily congested city with a record of 270 km traffic queue in 2010. Demand management has been applied, i.e. 20% of cars are not allowed to drive in the extended centre area between 7am and 10am and between 5pm and 8pm on weekdays. São Paulo has a comprehensive public transport service consisting of metro, train and buses. However, 45% of daily journeys use private cars. Traffic Engineering Company (CET) manages and maintains the traffic system in São Paulo city. The network consists of 5500 traffic lights of which 1000 are connected through ATCs in 8 zones. As expected, CET has been having difficulties controlling the network due to the equipment’s age (around 20 years old) and lack of a more thorough maintenance.
Viajeo in São Paulo
In São Paulo, the open platform will collect floating vehicle data from probe vehicles to evaluate the concept and to highlight benefits and potential deployment issues. These data will be integrated with existing data sources from the traffic control centre in the open platform in order to estimate real-time traffic condition. The real-time data will be stored in a historical data base for purposes of statistical and prognostic analysis as well as for the computation of optimal routes for private cars. Precise traffic profiles are going to be assigned to the road network of the demo area. Fleet operators may use the real-time information and historical database, which will be made available through standardized interfaces, for better operation and management of their fleet (e.g. Taxi). The real-time information and historical database will be used to support a web-based journey planner which will be able to plan a trip for private cars and commercial vehicles.
Moreover, the open platform will provide dynamic traffic information service which will be delivered to on-board units to enable the driver to avoid congestion. The application will be made available free of charge on well known application stores for one or more mobile platforms. The dynamic traffic information will also be disseminated through other media such as traveller information website. On-board equipment will be coupled with high band width communication link through the GPRS channel. Moreover the on-board units equipped for floating data collection will open up the opportunity for safety and security application with special emphasis on the European Commission's emergency standards and policies. Differing from other demo sites which focus on one urban area only, Brazil demo site will cover also surrounding motorways. The open platform will connect data from urban traffic control centres in São Paulo (CET) and data from motorway tolling system in order to estimate real-time traffic condition in urban and motorway networks. The open platform will access motorway traffic data via MIST platform which was developed by IPT and is currently used to collect traffic data on motorway networks from different operators.
