    Abstract
  • The signal control and optimization problems of urban traffic were studied. The total delay, fuel consumption and vehicle exhaust emission of road network were taken as optimization objectives, their calculation formulas were derived based on cell transmission model (CTM), and a multi-objective optimization method based on CTM for urban traffic signal control was presented. The solution of traffic signal was optimized by using multi-objective genetic algorithm. Simulation result shows that green wave bands form under mild, moderate and heavy traffic flow conditions, the coordination control of traffic signals can be achieved, and the optimization settings of intersection traffic signals are realized.
