摘要/Abstract

摘要： 面向设置双停车线和预信号的交叉口进口道,以实现主、预信号配时最优化及其最佳协调为目标,建立了主信号配时参数、预信号配时参数和主、预信号相位差3类变量的集成优化模型.考虑了主、预信号前不同方向车道数、饱和流量、信号周期、各流向的流量和待行区域长度等要素和约束,并刻画了主、预信号共同作用下待行区域内不同流向(左转、直行)车辆排队状态及其演化过程.最后结合一个实际案例进行分析,结果表明:相同的交通需求条件下,本文模型相对于传统模型可以大幅度地减少满足相同饱和度约束所需要的最小绿灯时间,有效地改善了交叉口运行效率.

Abstract: An integrated model was proposed for the optimization of signal timings for main-signal and pre-signal and their coordination on the approach of intersection with two stop lines and pre-signals. A set of constraints were taken into account in the model, including the number of lanes before the pre-signal and main-signal, the saturated flow of each movement, the cycle length and the length of sorting area. The queue evolution process of different movements (through movement and left turn movement) in the sorting was also addressed in detail. The proposed model is validated by a case study of a signalized intersection using field data. For a given traffic demand, the proposed model can meet the same degree of saturation with less total green time compared with traditional methods.

Key words: engineering of communications and transportation system, signal coordination, two stop-lines, pre-signal, queue length
