THE USES OF RADIOLOCATION OF VEHICLES IN RATP, AIGLE, AND ALTAIR, FOR SAFER AND BETTER INFORMED PASSENGERS

AIGLE and ALTAIR are innovative systems based on GPS satellite vehicle location in urban areas, for passenger information, bus schedule adherence and security purposes. After a conclusive prototype phase, the RATP decided to launch the experimental phase in 1993. In 1995, the entire system was operational. The year 1997 completed the experimental stage and in 1998-2000 the system will be deployed throughout half of the network (4000 buses) since the initial objectives have been attained. In 1993, after a conclusive prototype period which had started in 1991, the RATP decided to start experimental application of ALTAIR, a GPS-based surface vehicle radiolocation system. The purpose of this phase was to demonstrate this innovative method of bus location in urban zones using satellites in actual working conditions. The main objectives were passenger information, bus interval management and security. In October 1994 the first phase of vehicle location for security purposes (AIGLE system) had been completed. In April 1995, the entire system was operational in all aspects. 1997 has seen completion of the experiments by application to a particularly difficult line, and in 1998-2000 the system will be applied to half of the 4000 buses. Initial objectives, interestingly enough, have already been attained. For the covering abstract see IRRD E102946.
