摘　　要：单个交叉口信控是干线和区域协调控制的基础,探索单个交叉口信号配时优化的最优方法,对构建干线和区域协调控制具有重要意义.研究选取并对比了Webster方法、ARRB方法、HCM2000方法、延误-通行能力联合双目标方法、基于模糊算法的配时方法、以及基于遗传算法的配时方法等6种交叉口信号配时经典方法,以实际交叉口为案例,运用VISSIM仿真软件定量化评价了不同配时优化方法在非饱和、饱和、过饱和状态下的信号配时优化效果.研究表明,在非饱和状态下,HCM2000方法最优;饱和及过饱和状态下,遗传算法(GA)方法最优.Single cross message control was the basis of coordinated control between trunk and area.It was great significance that explore the optimal method of signal timing optimization for single intersection to construct coordinated control between trunk and area.In this paper,Webster method,ARRB method,HCM2000 method,delay-capacity combined dual objective method,timing method based on fuzzy algorithm,and timing method based on genetic algorithm were selected and compared with six classic methods of intersection signal timing.The signal timing optimization effected of different timing optimization methods under unsaturated,saturated and supersaturated conditions were quantitatively evaluated by VISSIM simulation software.The results showed that HCM2000 method was the best under unsaturated condition.The genetic algorithm(GA)was the best in saturated and supersaturated state.
