CLAIRE-SITI, public and road transport network management control: a unified approach

Together with the SAGE development in Paris, INRETS launched in 1989 a European project called CLAIRE, part of the DRIVE I programme. The aim of CLAIRE was to develop an independent system for congestion monitoring and management which would be compatible with most traffic control systems. The SAGE system therefore had to be generalised; in addition, its capacities had to be extended to the off-line strategic functions of long term storage, congestion pattern recognition and strategies learning for congestion processing. Together with the improvement of the CLAIRE design in order to process congestion, INRETS has developed the SATIR system, which reduces the automatic vehicle monitoring (AVM) operator tasks in the case of disturbances. It has been implemented on the public transport network in Brussels and is operated by STIB. The synthesis of all this work has enabled us to progress towards a CLAIRE-SITI generic concept of a supervisory system of multimodal networks (SITI stands for Intelligent System for Intermodal Transport). This work is presented in the paper.
