【摘要】 通过对传统信号配时理论的分析,指出其主要适用于饱和度较低的交叉口。实际中交通高峰时期经常会出现过饱和交叉口,并导致交通"多米诺"现象。本文针对过饱和交叉口的交通特性,提出了优化滞留车辆的空间分布、防止排队上溯的控制目标,建立了一个考虑进口道长度的过饱和绿信比配时模型。最后通过模拟仿真说明与传统配时方法相比。本文提出的的模型更适应过饱和时的交通控制。更多还原

【Abstract】 Through analysis the traditional signal timing theory, pointing out that its main apply to the unsaturated intersection. Actually in the peak periods often appear over-saturated intersections and caused traffic "domino" phenomenon. Based on the characteristics of saturated intersection, this paper aims at optimized the spatial distribution of stranded vehicles and prevent queuing upstream, proposed a split model which has considered the length of imports. Finally, The simulation results prove that compared with the traditional method, his paper’ model is better suited to the traffic control of over-saturation intersection.更多还原
