摘要
Abstract
The effectiveness of arterial coordination control is affected by the randomness of traffic flow arrival and the fluctuation of driving speed.To address this issue,this study established a signal coordi-nation and speed guidance cooperative optimization model considering the influence of left-turn waiting ar-eas(LTWAs).This model incorporates the green signal ratio and phase offset design methods under dif-ferent signal phases,as well as the relationship between speed and phase offset during queue dissipation,and obtains the split,phase offset and speed scheme when the bandwidth reaches the maximum and the arterial delay reaches the minimum in a specific phase sequence.In addition,a signal transition method is designed to ensure the smooth operation of the signal transition scheme.Finally,the traffic simulation experimental environment was established based on Visual Studio and VISSIM.Two consecutive intersec-tions with LTWAs along Jiefang Avenue in Wuhan City were selected as the case study for simulation veri-fication.The experimental results showed that compared with the coordinated control method of arterial system with LTWAs without considering speed guidance,the average number of stops and average vehicle delay were reduced by 12.31%and 8.98%,respectively.This demonstrated that the proposed model could further improve the coordination control effect and traffic operation efficiency of the arterial system with LTWAs.关键词
