This paper studies the evaluation methods of the time and space variations of the dynamic traffic information on a traffic control system. The traffic control system is synthesized combining a signal control system and a dynamic route guidance system. The signal control system works to minimize the sum of error function of a traffic network by the feedback control of three signal control parameters. The dynamic route guidance system outputs recommendable routes and their travel time including the shortest mean travel time route and its travel time to drivers using the shortest mean travel time route algorithm. Applying the traffic control system to the traffic network, which is used most efficiently about reducing both the congestion length and the mean travel time. The information of the traffic control system are classified from viewpoints of static / dynamic and input / output. The static traffic information such as the link length, the lane number, the legal speed and the saturation flow are constant with respect to time. On the contrary, The dynamic traffic information such as the volume, the capacity, the queue length, the speed, the signal control parameters and the travel time are changeable with respect to time. In the signal control system, the dynamic traffic information such as the volumes, the queue lengths and the speeds are inputted to computers, and the optimal signal control parameters are outputted to signal controllers. In the dynamic route guidance system, the queue lengths, the speeds, the capacities and the optimal signal control parameters are inputted to computers, then the recommendable routes and their travel time are outputted to drivers. The dynamic traffic information are evaluated by following methods: The capacity of each signalized intersection is evaluated by summing up each lane capacity. Tne queue length is evaluated based on the volume balance at each signalized intersection. The optimal signal control parameters are evaluated by signal control algorithms using the feedback control. The mean travel time from a driver's origin to his destination is evaluated by the shortest mean travel time route algorithm.
