Abstract
This paper studies the dynamic route search of traffic networks which play an essential role in dynamic route guidance systems. The mean OD travel time is evaluated by summing up the mean travel time of each link. Two dynamic route search algorithms are presented; one is "the shortest distance route algorithm", the other is "the shortest mean travel time route algorithm". From the simulation results of the two dynamic route search algorithms, it is confirmed that the mean OD travel time vary remarkably depending on the traffic flow conditions, the signal control parameters and the number of time for the right-turn.
