HOW TO MOVE A MILLION CARS

The real-time traffic control system designed for Curitiba in Brazil is described. The street network is formed of a grid of one-way streets. The main constraint in the city centre is the relatively short length of city blocks, making queue formation critical in traffic control. In 1997 DATAPROM was awarded a contract for real-time control using the ANTARES system to increase bus priority on mass transport corridors. A more sophisticated version was introduced to manage traffic flows and congestion in the Batel city centre region. The components of the Control Centre are outlined. Basic traffic plans are developed using 'Swarm intelligence' in which the overall optimisation of a complex system is reached by interactions among the simple constituent elements. The system also uses 'Strategic masks' which are more forceful interventions implemented when congestion becomes serious. The stages used for installing ANTARES in the Batel region are outlined and operational results are discussed.
