Abstract

The traffic flow dynamics is described by a nonlinear discrete dynamic system at signalized intersections based on the volume balance. The mean link travel time are analyzed according to the classification of the traffic flow, offset control and moving direction at downstream signalized intersections in urban road networks. The mean link travel time are measured by the average rate of speed of the traffic stream which is one of test-car techniques. The mean link and OD travel time are evaluated for four routes in Fukuyama city, Japan according to their analyses. A dynamic route search algorithm which plays an essential role in the dynamic route guidance system is presented using the Dijkstra´s algorithm.
