【摘要】：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%。
[Abstract]:Coordination of Synchro software based on the intersection line properly divided, Synchro with the coordination factor to measure whether the need to implement the coordinated control between adjacent intersections, coordination factor mainly consider the travel time, distance, traffic, team form, cycle length and other factors; and then analyzes the coordination optimization logic, and use method traffic simulation analysis of different partitioning strategies on control effect, and select the best partition; analyze the case of 61 along the road 11 intersection, the effectiveness of Synchro in intersections in the division of verified. The results show that the Coordination Division will significantly influence the intersection delay and stop the vehicle in the network, the division of appropriate cause delays increased significantly. But no matter what kind of division, will significantly reduce the main road and the whole network the number of parking. The best way to make the whole division Network delay is reduced by 10%, and the average number of parking is reduced by 11%.
