OPTIMAL CONTROL OF URBAN TRAFFIC SIGNALS BY MEANS OF BAND TRANSFORMATION

In this paper, an adaptive optimization procedure for traffic signal systems via multi-band modeling is proposed. The urban traffic behavior at an intersection is described in terms of oversaturated, saturated and free-flowing bands. Only three attributes are needed to describe a band at an intersection approach. The adaptive optimization procedure predicts a surface, whose shape is generally unknown, via an approximate-analytic method and incorporates learning from experience concerning the locations of local minima from the predicted performance characteristics along unidirectional searches.
