摘要：

为解决交叉口因BRT优先影响其他车辆通行问题，提出基于交叉口双站台的BRT 优先控制方法. 给出交叉口BRT双站台设置方法，对比分析BRT在交叉口单、双站台的平均延误. 根据BRT发车时刻、交叉口信号配时、BRT平均车速、交叉口间距及站台停靠时间等，制定 BRT站台预停靠方案和行车时刻表. 为确保BRT按照预停靠站台及时刻表运行，采用BRT车速引导与信号配时双重补偿修正BRT 实际离站时刻与时刻表的偏差. 以常州BRT 1 号线为例，对应用本文方法的5 个交叉口进行分析. 结果表明：BRT在每个站台实际离站时刻偏差范围为±5 s、±10 s、±20 s 时，本文优先控制方法显著减少BRT停车次数和延误，提高了BRT整体运营效率.

Abstract:

BRT has a priority at intersections, which affects the traffic flow of other vehicles. A BRT priority control method is proposed for two-station intersections. This paper first describes the setting of the BRT double stations at the intersection and compares the single and double stations at the intersection in terms of the average BRT delay. Then, the BRT pre- stopping scheme and the driving schedule are proposed, according to the BRT departure time, the intersection signal timing, the average running speed, the intersection spacing, and the dwell time. In order to ensure that the BRT operates in accordance with the stopping scheme and schedule, a method is proposed by using BRT vehicle speed guidance and signal timing double compensation to correct the deviation of the actual departure time of the BRT from the timetable. Taking Changzhou BRT Line 1 as an example, five intersections are adopted to verify this method. The calculation results show that when the deviation range of BRT at the actual departure time of each station is ±5 s, ±10 s, ±20 s, the priority control method can significantly reduce the number and delay of BRT parking and improve the overall operational efficiency of BRT.
