A signal control intersection increases not only vehicle delay, but also capacity reduction in that area. Because more and more fuel and air pollution problems arise recently, an intersection signal control optimization method which aims at reducing vehicle delay, improving capacity is required heavily. This paper proposed a signal control multi-object optimization method to reduce vehicle delay and improve intersection capacity simultaneously at an intersection by using the Genetic Algorithm (GA). Data regarding traffic stream parameters, signal timing details and delay to vehicles are collected from an intersection in Shanghai, Hu Cheng Huan road. The result of the case study shows the optimal timing scheme obtained from this method is better than the observed one.
