MONITORING THE MONSTER: ENHANCING THE TRANSPORTATION SYSTEM IN A GROWING METROPOLIS

Sao Paulo in Brazil is now one of the world's fastest growing cities. It needs an innovative Intelligent Transport System (ITS) to monitor its monstrous traffic problems, and it is now beginning to develop one. This article describes the ITS that PB Farradyne and Hagler Bailly Services are currently designing, which uses information collected through communications between in-vehicle transponders, or toll tags, and roadside readers as vehicles move through the road network, to monitor traffic. A map shows the layout of Sao Paulo's principal highways, which include concession toll roads. A regional approach is being used in the design of the ITS architecture. A proposed solution was developed that includes: (1) a surveillance system based on the use of toll tags; (2) a traffic control system that will use these elements and introduce standards to enable data sharing; and (3) an expanded telephone system to encourage more cellular telephone users to report incidents. An independent evaluation of the TRANSMIT system in the USA has found that toll tags can effectively detect incidents and collect travel-time data. The article describes a proposed system for Sao Paulo, using TRANSMIT, that will provide the public with real-time data and advisory information through a range of distribution mechanisms.
