Traffic Optimization Control Model Based on a New Hybrid Algorithm

Under the conditions of given intersection space de sign and signal phases and with the restriction of traffic delays (level of serv ice) of motor vehicles and non-motor vehicles, this paper presents an optimizat ion model for the maximum motor vehicle traffic capacity using the traffic flow control theory. And the model is solved by a hybrid algorithm, which combines g enetic algorithm with chaos optimization algorithm. The results of actual calcul ation indicate that the theory value and practice value of the optimization mode l are high. New ideas and methods are provided for the coordinate and optimal co ntrol of the traffic flows in signalized intersections.
