Simulation of traffic flow at a signalized intersection

Abstract

We have developed a Nagel–Schreckenberg cellular automata model for describing vehicular traffic flow at a single intersection. A set of traffic lights operating either in fixed time or in a traffic adaptive scheme controls the traffic flow. A closed boundary condition is applied to the streets, each of which conducts a unidirectional flow. Extensive Monte Carlo simulations are carried out to establish the model characteristics. In particular, we investigate the dependence of the flows on the signalization parameters.
