| 摘 要： | 以某市一孤立单交叉路口为例，在双模糊控制器协调控制获得相序和各相位的绿灯时长的基础上，提出了一种采用将遗传算法和模拟退火有效结合的GASA混合算法，设计了城市单交叉路口的多相位信号配时控制方案.Matlab仿真结果表明这种新算法可以达到避免局部最优、更快实现全局收敛的目的，与单纯采用遗传算法优化控制器参数相比，可以实现更小的平均车辆延误，保证车队更顺畅地通过交叉路口.

| Abstract: | For an isolated traffic intersection,dual-fuzzycontrollers can be employed to obtain phase sequence and green light time length of each phase.And thus,a new on-line parameter-optimization mixed algorithm combining genetic algorithm with simulated annealing algorithm has been proposed.This new scheme has been applied in the multi-phase traffic signal timing for an urban isolated intersection.The simulation results show that the new algorithm is able to realize better and faster global convergence compared with parameter optimizaiton realized only by genetic algorithm.Furthermore,the less average delay time for each vehicle can be acheved,and the vehicles can pass through the isolated traffic intersection more successfully. |

| Keywords: | genetic algorithm simulated annealing parameter optimization traffic signal timing isolated traffic intersection |
