A distributed simulator for road network control

This paper is about a distributed implementation of a road traffic simulator. The simulator will be used in an integrated, operational system for road traffic monitoring, visualization, prediction and control. The distributed implementation is needed in order to make the simulator scalable (especially with respect to road network size) and to make it comply with real-time requirements stemming from on-line use in control and decision support systems, with emphasis on network control rather than local control. The underlying traffic model is a first order, multi-class model. The implementation has been tested with the network of the Amsterdam A10 beltway.
