摘　　要：针对进口道渠化左转短车道的信号交叉口,研究交叉口时空资源的最优配置。基于短车道对进口道饱和流率的影响,建立联合优化配时模型。以大连市典型交叉口为例,运用MATLAB对优化模型进行求解,并通过VISSIM软件进行仿真试验。研究结果表明,交通组织与信号控制的协同设计可以实现交叉口时空资源的最优配置,从而充分发挥交叉口的能效。The optimal configuration of time and space resources was discussed in allusion to the signalized intersections where the left-turn short lane had been channeled.According to analyzing the impact of short lane on saturation flow rate of approach,a combined signal timing optimization model was established and solved by applying MATLAB and using traffic survey data from Dalian City.Then the simulated experiments were designed by VISSIM.The results show that the synergistic design of traffic organization and signal control can optimally configure time and space resources of intersection so that the performance of intersection can be fully exerted.
