摘　　要：BRT与传统的公交相比具有快捷、准点和安全的优势,但不同时段和路段的客流需求的变化,以及交叉口、天气和驾驶员水平等因素的影响,导致出现车头时距不稳定现象。为了分析BRT运行途中的车头时距变化规律,选取BRT的两个车站作为研究地点,对比了9:00—11:30平峰期和11:30—12:30午高峰期车辆到达和离开车站的车头时距特征,运用MATLAB对采集的数据进行拟合优度检验分析,结果表明BRT车头时距特征符合对数正态分布。本研究结论可为BRT交通流特性的研究和调度提供理论依据。Compared with the traditional bus,BRT has the advantages of speed,punctuality and safety.However,due to the change of passenger flow demand in different periods and sections,and the influence of intersection,weather and driver level conditions,the headway is often unstable.In order to analyze the variation rule of headway during BRT operation,this paper selects two stations of BRT to compare the characteristics of the headway of vehicles arriving at and leaving the station during the non-peak period of 9:00-11:30 and the peak period of 11:30-12:30,and uses MATLAB to conduct goodness of fit test analysis on the collected data.The results show that the characteristics of BRT are lognormal.The conclusion of this study can provide a theoretical basis for the study of BRT traffic flow characteristics and scheduling.
