Abstract :
Travel time is a measure of traffic flows in traffic networks and indispensable for the dynamic route guidance system. The queue length and congestion length are 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 congestion, offset control and moving direction at downstream signalized intersections in urban traffic 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 three routes in Fukuyama city according to their analyses. The evaluation values of mean link travel time are compared with the measurement values for each time interval
