摘　　要：梳理了各地现行公交专用道设计规范,得出公交专用道的设置条件通常只考虑了高峰小时道路断面公交客运量、公交车流量、道路条件等客观指标,鲜有考虑道路上公交线路的运行稳定性及其对乘客公交服务可靠性体验提升的影响。针对公交专用道可靠性和效率评估中由于公交专用道设置条件的缺失,造成部分公交专用道运行效果不良、乘客体验感无提升的问题,本文考虑了乘客体验,提出了基于公交运行稳定性的潜在公交专用道需求识别方法。该方法基于实际路况和公交车辆全球定位系统(GPS)数据,分析了公交车辆在各路段或站段上偏离计划行车时刻表运行的情况,构建了公交拥堵指数和公交运送时间波动性两个指标。提出了基于公交运行稳定性的路段或站段分级方法,并将该方法用于上海中心城69条公交线路的途经道路,把识别出的公交运行稳定性为“差”的道路作为公交专用道潜在设置需求,同时,该方法也可锁定需要进一步优化改善的公交专用道。Combing the existing public transportation lane design specifications around the world,it is concluded that the setting of bus lanes usually considers the peak hour road bus passenger volume of section,bus traffic volume of sections,road conditions and other objective indicators,with little consideration given to the operational stability of bus routes on the road and its influence of improving passengers'experience of bus service reliability.In the post-operation evaluation of the public transportation lanes,operational reliability and efficiency assessment are finished regularly.Due to the lack of conditions for setting up dedicated bus lanes,some dedicated bus lanes have poor operational effects and no improvement in passenger experience.Therefore,considering passenger experience,a potential public transportation lane demand identification method based on the stability of bus operation was proposed.Based on the actual road conditions and bus vehicle GPS data,the deviation of bus vehicles from the planned schedule on each road section or station was analyzed,and two indicators,namely the bus congestion index and bus delivery time volatility were constructed,to form a classification method based on bus operation stability of road sections or stations.The proposed method was applied to the roads of 69 bus routes in central Shanghai,and the identified roads with poor bus operation stability were considered as potential needs for public transportation lanes.The method can also target public transportation lanes that need further optimization and improvement.
