Abstract
In a traffic signal control apparatus that can correspond to sudden change in the traffic status, traffic information is collected from a sensor provided at the road to obtain the status of a street intersection from the past to the future as profile data. By the rolling horizon scheme, optimization of the signal timing is carried out. The collect cycle of traffic information and the cycle of optimization are defined independently, and the cycle of optimization is set variable according to the cycle of signal control or the traffic status.
