城市道路两相邻交叉口信号控制组合优化研究

his article takes a simple green wave system composed by two simple points signal control intersections as an example, and makes a non-liner function model, in which the shortest vehicle travel time of main stem is adopted as the objective; the phase effective green light time, saturation and cycle time as the restrictions. The genetic algorithm and genetic annealing algorithm are used to optimize the objective function, Thus realizing the optimization design to the intersection signal timing of the green wave system. The model and algorithm are proved by an actual example, and a good optimized effect can be gotten. The results show that the genetic annealing algorithm can find the best value faster and accurater than the genetic algorithm.
