摘要: 人类驾驶的不可控性使得间歇优先公交专用道(BusLaneswithIntermittentPriority,BLIP)不能被有效利用。为解决该问题,本文提出智能网联车辆(ConnectedandAutomatedVehicles,CAV)复用BLIP的控制方法。CAV借道控制考虑了公交车间移动区间的约束,还道控制考虑了与旁道CAV队列的协同,以应对还道安全距离不足的情况。并利用开放边界元胞自动机模型对提出的方法进行仿真。结果表明:同等流量下,CAV复用BLIP可大幅提高道路通行效率,且中等CAV渗透率下最显著,道路平均速度从6.67km·h-1提高至30.53 km·h-1;无论CAV渗透率高低,CAV队列协同换道都比单个CAV协同换道更有助于提高道路通行效率,相较之下将道路平均速度提高8%~19%。

Abstract: The uncontrollability inherent in human-driven vehicles poses challenges to the efficient utilization of bus lanes with intermittent priority (BLIP). To address this issue, a control method for reusing BLIP in connected and automated vehicles (CAVs) is proposed. The lane-borrowing control takes into account the time-space constraints of bus movements, while the lane-returning control focuses on coordinating with adjacent CAV platoons to handle scenarios where the safe distance for lane-return is inadequate. The proposed method is simulated via an open-boundary cellular automaton model. Simulation results showed that: (1) At a given traffic flow, reusing BLIP with CAV can significantly improve road traffic efficiency. Notably, a moderate CAV penetration rate yields the most substantial improvement, with the average road speed rising from 6.67 km·h-1 to 30.53 km·h-1. (2) Irrespective of the CAV penetration rate, collaborative lane-changing within CAV platoons is more effective in boosting road traffic efficiency compared to single-CAV collaborative lane-changing, with an increase in the average road speed by 8%~19%.

Key words: intelligent transportation, bus lane reutilization, CAVs queue collaboration, CAV control method, vehicular networking
