摘　　要：研究目的:宜宾市智能轨道快运系统T1线是一条覆盖城市发展主轴主要客流走廊、加强长江两岸间联系的中运量公共交通骨干线。宜宾智轨T1线的建成运营有效改善了沿线城市交通条件,满足了主、副城区之间居民出行需要。本研究旨在结合智轨T1线项目营运案例提出一种既可实现智轨车辆快速不停车通过交叉口,又能提高交叉口范围智轨车道使用率的信控方案,为后续智轨建设项目确定信控方案提供借鉴。研究结论:(1)以宜宾市智能轨道快运系统T1线工程项目为例,提出基于信号优先及路口智轨车道路权共享策略的路口信控方案,该方案主要包括智轨信号优先、交叉口范围智轨车道路权共享两个方面;(2)该方案通过路口雷视一体机采集实时车流信息,应用AI(人工智能)技术实现单个路口智能感应,线路绿波协调控制,到区域协调联动实现智轨路口通行效率的最大化;(3)该方案保障了智轨车辆快速通行、避免路口信号延误、有效提高智轨车道使用效率,实现路口通行效率最大化;(4)本研究成果可以应用在智轨系统领域,以解决智轨车辆路口高效通行,提升路口车道使用率问题。Research purposes:The ART T1 line of Yibin city is a medium-capacity public transportation backbone line that covers the main passenger flow corridors of the city's development axis and strengthens the connection between the two banks of the Yangtze River.The completion and operation of the T1 line can effectively improve the urban transportation conditions along the line and meet the travel needs of residents between the main and suburban areas.Through this study,the aim is to propose a signal control strategy that not only enables ART to pass through intersections quickly without stopping but also improves the utilization rate of ART lanes within the intersection area,based on the actual operation case of the Yibin T1 Line project.This will provide a reference for determining signal control schemes for the construction of ART projects subsequently.Research conclusions:(1)Taking the ART T1 line of Yibin city as an example,the signal control scheme based on signal priority and right-of-way sharing strategies at intersections is proposed.It mainly includes two aspects that are signal priority for ART and right-of-way sharing strategies for ART lanes at intersections.(2)Real-time traffic flow information is collected through the installation of radar-vision integrated machines at intersections,and AI(artificial intelligence)technology is applied to achieve intelligent sensing at a single intersection and coordinated control of green waves to coordinate and link in the region,thereby maximizing the traffic efficiency of intersections.(3)The signal control strategy ensures the rapid passage of ART,avoids signal delay at intersections,improves the utilization efficiency of ART lanes,and achieves the maximization of traffic efficiency at intersections.(4)The research results are mainly applied in the field of ART to solve the problem of ART vehicles efficiently passing intersections and improving the utilization rate of intersection lanes.
