摘要
根据信号交叉口已知的车道设置情况和交叉口控制条件可以判断进口道总人均延误值是否最小,该值与进口道交通量及公交比例有关,其结论可以用于指导上游路段的交通控制。以交叉口人均延误最小化为目标,假定交叉口信号配时、入口车道数、入口车道通行能力等条件不变,采用VISSIM仿真模型进行分析,结果表明,当车道设置条件和交叉口控制条件不变时,随着入口交通量的增大(饱和度从0.5增加至1),最佳公交流量比例逐步上升。
Based on the known traffic lane settlement and traffic control methods at a signalized intersection,it can be judged whether the average delay time is the least according to the given traffic volume and bus percentage.The result can be used to guide traffic control in the upper approaches.With an objective of minimizing the average delay time and supposing the signal timing,the number of traffic lanes and their capacities unchanged,and a simulation was carried with VISSIM.The result showed that with the increase of traffic inflow(the saturated rate increasing from 0.5 to 1),the best percentage of buses also increased.
