摘要:

在绿波协调控制交叉口群中,为分析公交优先控制对后续交叉口群的扰动,基于车流运行时间偏移分布,以概率期望描述了交叉口各相位绿时左端和右端时长变化引起的后续交叉口群在绿波带内、绿波带间的延误变化;采用组合优化的方法,以交叉口群在车速引导下的公交通行效益优化为上层模型,以交叉口群在公交优先控制下的延误优化为下层模型,对公交引导车速和信号控制参数进行协同优化.通过算例分析表明,公交优先控制模型有效提升了交叉口整体通行效益,最大化减小了对周边交叉口群的不利影响.

Abstract:

In order to analyze the perturbation of the bus-priority control to the intersection group under the green-wave coordinated control, delay changes of the subsequent intersection group in and between green wave bands are described by the probability expectation of the length changes in each intersection signal green phase left and right ends, based on the analysis of traffic flow run- time migration distribution. The guiding speed of bus and the parameters of signal control are optimized collectively by the combinatorial optimization model, in which the upper model is to optimize the bus traffic efficiency of the intersection group under the guiding speed and the lower model is to optimize the delay of the intersection group under bus priority control. The example shows that the bus priority control model could effectively improve the intersection traffic efficiency and minimize adverse effects on surrounding intersections.

Key words: urban traffic, bus priority control, delay, green wave coordinated control, cooperative vehicle infrastructure system
