Abstract
In this paper, the authors present a procedure for optimal trajectory control of vehicles in a urban automatic taxi system “AXAR” . This P.R.T.(Personnel Rapid Transit) is characterized by a decentralized structure and does not need neither a central décision making center nor a data collecting system. In this system, the decision for taking this or that way to arrive any point of the network is entrusted to a simple microcomputer Installed on the vehicle. The paper presents how the optimisation of trajectory can be realized by an “off line” computer. The results of this calculation are then given to a microcomputer which find on the vehicle. The investigation is based on a real urban network data of a medium town near Toulouse (France). The simulation results permit to appreciate the effectiveness of the “AXAR” system in the studied case and in its particular difficult conditions.
