摘　　要：为了给公共交通改善指标及公交优先对策制定提供参考,以深圳市晚高峰出行数据为样本,对公共交通与小汽车的出行时耗比构成特征及影响因素进行了分析。根据公共交通车外时耗和车内时耗在出行时耗中所占的比例,将样本划分为出行时耗比由车外时耗占主导影响和车内时耗占主导影响两类,并计算每一类中各相关因素对出行时耗比的影响程度。结果表明:超过90%的样本出行时耗比受公共交通车内时耗主导影响;在车外时耗相关因素中,两端步行距离对出行时耗比影响程度较大;公共交通路径绕行及出行速度低对出行时耗比造成的影响中,后者影响程度更加明显。In order to provide references for transit improvement target and strategy of transit priority,composition features of traveling duration radio(TDR)of transit and private cars and influencing factors were analysed,based on the data of evening peak hours in Shenzhen.According to the proportion from the total traveling duration of transit,the sample was divided into cases that in-transit or out-of-transit duration time dominates,and the degree of influence of related factors to the total TDR was calculated individually.Research shows that in-transit duration is the primary influencing factor of TDR in more than 90%sample.Walking distance at both ends makes major impact on TDR among factors related to out-of-transit duration.Lower traveling speed of bus causes more significant impact to TDR,compared with longer route.
