快速公交专用道形式对其运行效率的影响研究

Influence of Bus Rapid Transit Lanes Configuration on Its Operational Efficiencies

选取包含有四段不同专用道形式的济南市BRT-3线路为研究对象,通过实时采集各区段和站间的运行数据,运用数理统计方法和多元分析理论,对该线路中不同区段和站间的BRT车辆运行效率、该线路具有的车辆配置、信号配时以及道路基础条件的特点对BRT运行效率的差异性,不同区段上交叉口停车延误和停靠站延误进行对比分析。提出了实行部分交叉口有条件的BRT信号优先;优化行人街交叉口;实时调度控制车辆运行时间和距离等改进措施。

The BRT-3 Line of Jinan City was studied,which contains four different sections.The operational data of every section and between stations were collected in real time.Mathematical statistics and multivariate analysis were used to analyze the operational efficiencies of different sections and different stations.The BRT operational efficiencies were analyzed based on the vehicle allocation,signal timing and conditions of the lane.The comparative analysis of the intersection delay and the stop station delay in different sections was made in this study.It can provide the theoretical basis and technical support for the future BRT reasonable planning and scientific operational management.According to the research results,the specific improvement measures are developed.
