摘　　要：为解决临近城区的高速公路收费站与衔接交叉口区段短距离交织变道导致车辆排队溢出的问题,通过剖析衔接区段常规设计车流交通冲突关系,引入借道左转设计理念,提出了一种高速公路收费站衔接交叉口借道左转优化设计方法。分析衔接区段优化设计车辆运行特征,给出了收费站与衔接交叉口协同控制策略。以车均延误最小化作为目标函数,考虑主信号控制、预信号控制、收费站流量控制等约束条件,建立了协同控制优化模型。研究结果表明:优化设计与常规设计相比,车均延误降低比例最大值能达到12.91%,能够有效缓解衔接区段交通拥堵;优化设计车均延误降低比例随交通需求、左转比例的增加而增加,在高流量、高左转比例场景下,优化设计通行效率提升优势更加明显。To solve the problem of vehicle queue overflow caused by short distance interweaving and lane changing at toll stations and adjacent intersection sections near urban areas,a design method for optimizing the left turn of borrowing lanes at adjacent intersections of toll stations on expressways is proposed by analyzing the conventional design traffic conflict relationship of adjacent sections and introducing the design concept of borrowing lanes for contraflow left-turn.The optimization design of vehicle operation characteristics in the adjacent section is analyzed,and a collaborative control strategy for toll stations and adjacent intersections is proposed.A collaborative control optimization model is established with the objective function of minimizing average vehicle delay,taking into account constraints such as main signal control,pre-signal control,and toll station flow control.The research results show that compared with conventional design,optimized design can achieve a maximum reduction of 12.91%in average vehicle delay,which can effectively alleviate traffic congestion in adjacent sections.The proportion of average delay reduction for optimized design vehicles increases with the increase of traffic demand and left turn ratio.In high flow and high left turn ratio scenarios,the advantage of improving traffic efficiency through optimized design is more obvious.
