摘　　要：针对BRT在环形交叉口占用空间大、速度慢,交织影响通行效率等问题,研究在分析常规环形交叉口BRT通过特性的基础上,从BRT车道的适用条件、在环形交叉口的冲突等角度,对BRT车道在环形交叉口的适应性进行了分析,并给出了相应的建议。特别是针对环形交叉口内部BRT车道宽度这个关键影响因素,通过VISSIM交通仿真建模,分析比较了不同车道宽度下,环形交叉口内不同种类车辆的延误、等待时间和停车次数等评价指标。相关的仿真结果表明,环形交叉口内BRT车道宽度为4m时,其在环形交叉口的延误最小,仅为8s;当BRT车道宽度增至5m时,会出现其他车辆抢道现象,造成BRT公交延误增加的现象。To address the problems of BRT(Bus Rapid Transit)operation at roundabout intersections,such as large space occupation,slow speed,and interweaving easily affects the traffic efficiency,this study analyzes the adaptability of BRT lanes at roundabout intersections based on the analysis of BRT passing characteristics at conventional roundabout intersections,from the perspectives of applicable conditions of BRT lanes and conflicts at roundabout intersections,and gives corresponding suggestions.In particular,for the key influencing factor of BRT lane width inside the roundabout intersection,VISSIM traffic simulation modeling is used to analyze and compare the delay,waiting time and stopping times of different types of vehicles within the roundabout intersection for different lane widths.The related results show that when the BRT lane width within the roundabout is 4m,its delay at the roundabout is the smallest at 8s;when the BRT lane width increases to 5m,other vehicles will grab the lane,causing the phenomenon of increased BRT bus delay.
