基于Synchro软件对干线协调的路口进行恰当地划分,Synchro软件中用协调因子来衡量相邻路口间是否需要实行协调控制,协调因子的计算主要考虑行程时间、距离、流量、车队形式、周期时长等因素;然后分析了干线协调优化逻辑,并用交通仿真的方法分析不同划分策略对控制效果的影响,并选取最佳的划分;对六一路全线11个交叉口进行案例分析,Synchro在协调路口划分中的有效性得到验证。结果表明协调路口划分会显著地影响整个网络中车辆的延误和停车次数,不恰当的划分会导致延误大幅增加。但不论哪种划分方式,都会显著减小主路和整个网络的停车次数。最佳的划分方式使整个网络延误降低10%,平均停车次数降低11%。
Synchro software based on the intersection of trunk coordination properly divided, Synchro software used to measure the coordination between adjacent junctions need to implement coordinated control, coordination factor calculation mainly consider the travel time, distance, traffic, the formation of the fleet, the cycle time And then analyzes the mainline coordination and optimization logic, and analyzes the impact of different division strategies on the control effect by traffic simulation method, and selects the best division; case analysis of 11 intersections across Liuyi Road, Synchro in the coordination of road junctions The validity of the validation. The results show that the coordination of road junctions will significantly affect the vehicle delay and parking number throughout the network, inappropriate division will lead to a substantial increase in delay. But no matter what kind of division, will significantly reduce the number of stops on the main road and the entire network. The best way to divide is to reduce the entire network delay by 10% and reduce the average number of stops by 11%.
