THE MODELING OF REALISTIC AUTOMATIC VEHICLE LOCATIONING SYSTEMS FOR SERVICE AND TRAFFIC CONTROL

The increasingly widespread use of automatic vehicle location (AVL) systems offers many possibilities for improved service control through frequent updates of vehicle position. Potential applications incldue the improvement of passenger information at bus stops and in-vehicle, and methods to support demand-responsive transport and public transport priority. This paper reports on recent research into the modeling of realistic AVL systems using a simulation method. In the paper, attention is given to the modeling of generic beacon-based AVL systems and the method that was adopted is described. Recent literature suggests that global positioning system (GPS)-based systems have also now developed sufficiently to allow an accuracy of about 10 m. The principal reason for this greater accuracy is the correction of the "raw" GPS using the differential GPS technique. This paper describes research into the modeling of a more accurate representation of GPS-based AVL. Results from the simulation are presented and the benefits for service and traffic control to be gained from being able to collect more and better information are discussed.
