Design of a Multi-Route Optimal Simulation System for Urban Traffic Controls

In order to optimize urban traffic control to ease urban traffic, a multi line coordination control optimization and simulation model of urban traffic is  proposed. And the algorithm of space time phase evolution and the improved genetic algorithm (GA) based on the model are  given also. After summing up the system architecture, data structure and technical course, a multi line coordination control optimization and simulation system of urban traffic were completed. The simulation system and its modeling are simple, and it can be applied to any optimization of urban traffic control, in order to solve the problem of multi line coordination of urban traffic control (multi line green wave).By the actual modeling and simulation on a road network of Foshan city, the system achieves good results on urban traffic control optimization.
