摘要
对混合交通条件下基本车道饱和流量的各影响因素进行了分析,对比基本车道饱和流量影响因素修正方法,给出了基本车道饱和流量及各类车道通用校正系数常用计算方法。分析了公交车在连线上的运行特性,基于单点定时式公交优先信号配时模型,以人均延误最小为目标,建立了定时式两相邻交叉口公交优先信号协调配时模型;基于以人总延误最小为目标建立了定周期两相邻交叉口公交优先信号协调配时模型。利用实际调查数据,采用仿真分析方法验证本文提出的混合交通条件下定时式两相邻交叉口公交优先信号协调配时模型的正确性。
Basic conditions for mixed traffic lane saturation flow of the factors are analysed. Compared with the basic factors that influence the flow lane saturation methods, the article gives a commonly used method for basic flow and various lane to lane saturation correction factor. Analysed the operation of public transport vehicles in New Identity. Based on independent bus priority signal control planning and coordinated control tbeoretics in area, aims at minimum per capita delay at neighboring two intersections, sets up bus priority signal control model for neighboring intersections model. And between rain-cycle and max-cycle by advanced length optimizes system cycle. Under saturation of intersection less than threshold optimizes Green Period Ratio.
