中文摘要：

针对信号控制的交叉口存在高饱和度的相位,且相位间饱和度不同的情况,提出了一种基于博弈论的信号配时方法,实时缓解了高饱和度进口车道的拥堵,降低了进口道延误.对于不同饱和度下的车道,通过解析流量与信号配时的博弈关系,建立了基于博弈论的信号配时模型,设定了新配时方案的迭代步骤以及相关参数的标定.通过算例分析现状信号配时的效果以及现状车流的需求,饱和度较低的相位博弈分配到的有效绿灯时间降低,进口车道延误上升7.23％;而饱和度较高的相位博弈分配到的有效绿灯时间增加,进口车道延误降低了5.91％;该进口道的总延误降低1.03％,优于原来的信号配时方案.

英文摘要：

According to the situation that at the intersection of signal control exist high saturation phase as well as different saturation between phases,a kind of signal timing method was put forward based on the game theory to alleviate the traffic congestion of high saturation approaches and to reduce the delay.According to the different saturation of lanes,based on the analysis of game relationship between flow and signal timing,a signal timing model was built in the light of the game theory.Iteration steps of a new timing plan were set up and related parameters were calibrated.The effect of the presented signal timing and the present situation of traffic demand were analysed with practical examples.The results show that the assigned effective green time of low saturation phase reduces,the approach delay rises by 7.23％; the assigned effective green time of high saturation phase increases,the approach delay reduces by 5.91％ ; and the total delay of approaches reduces by 1.03％,being better than the original signal timing plan.
