Real-time aid to decision system for bus operators

The progress in telematics at the level of surface public transport resulted in the progressive implementation of centralised fleet management systems based on automatic vehicle monitoring systems (AVM). However faced with the many disturbances on public transport, the operators have much difficulty in detecting situations with problems and make the right decisions. In this respect the decision domain, Scemama and Gaudin (1998), represents a major challenge for the new AVM generation. The paper presents a decision aid system for AVM operators, called SATIR (“Systeme d´Aide au Traitement des Incidents pour les Regulateurs”). After an introduction presenting the state of the art of AVM systems, the functions of SATIR are presented. Then its technical achievement and the first results of its assessment on the public transport network of STIB in Brussels are addressed
