摘要
基于3组道路交叉口交通信息检测器的布设,可实现对交叉口交通流的运行状态信息检测.研究车队头车的特征、判断逻辑和方法,并分析车队尾车的判断逻辑和车队追加的方法,进而提出排队统计开始时刻、排队统计策略,以及排队算法,力求获得较为准确的排队数据.车队检测方法、路口排队统计方法和排队消散方法将为交通控制策略提供信息和技术基础.
Based on three groups of the layouts of traffic information detectors at road intersections,the operating state and information of traffic flow at the intersection can be detected. This paper studies the characteristics, the judging logic and method of the leader in the motorcade, analyzes the judging logic of the rear car in the motorcade and the method of additional motorcade, then puts forward the starting time and the strategies of queue statistics and queuing algorithms in order to obtain more accurate queuing data. The testing methods of the motorcade, the methods of queuing statistics at the intersection and the vehicle-queues- dredged method will provide informational and technical basis for traffic control strategies.
