摘要:
为解决多股跨相车流及非关键车流在未饱和信号交叉口的通行时间分配问题,提出了一种基于车流通行需求的绿信比分配目标函数,建立了交叉口绿信比的基础分配模型与多轮分配模型,给出了绿信比与相位时间的分配流程,设计了一种程序化的交叉口绿信比分配方法,并结合算例阐明了模型方法的求解过程.选取广州市某信号交叉口进行案例分析,与现行配时方案和Synchro优化配时方案相比,所提模型优化配时方案的非关键车流及跨相车流整体延误时间在VISSIM仿真实验中分别减少了22.3%和9.1%,在Synchro仿真实验中分别减少了15.4%和4.8%.模型通过对绿信比与相位时间的多轮分配,实现了对非关键及跨相车流通行时间的优化,可以更好地满足信号交叉口各股车流的通行需求.
Abstract:
To solve the problem of green time allocation of multiple overlap phase movement and non-critical movement at unsaturated signalized intersection, an objective function of split allocation based on traffic demands was proposed. The basic split allocation model and the multi-round split allocation model of intersection were built. And the allocation process of the split and phase time was given. Then, a procedural intersection split allocation method was designed, and the solving process of the model was illustrated by examples. The results of a case study of a signalized intersection in Guangzhou show that compared with the current timing scheme and the Synchro optimized timing scheme, the overall delay time of the non-critical movement and the overlap phase movement performed by the optimized timing scheme is reduced by 22.3% and 9.1% in the VISSIM simulation experiment, and reduced by 15.4% and 4.8% respectively in the Synchro simulation experiment. Through the multi-round allocation of split and phase time, the model can realize the green time optimization of the non-critical movement and overlap phase movement, meeting the traffic demands of each movement at signalized intersections.
