Abstract:Simultaneous PerturbationStochastic Approximation (SPSA) has gradually gained favor as an efficient method for optimizing computationally expensive, "black box" traffic simulations. However, few recent studies have investigated the efficiency of SPSA for traffic signal timing optimization. It is important for this to be investigated, because significant room for improvement exists in the area of signal optimization. Some signal timing methods and products perform optimization very quickly, but deliver mediocre… Show more
