| 摘 要： | 研究的主要内容为:未设置右转专用相位的信号灯控制道路交叉口右转机动车流与行人和非机动车的冲突行为,包括冲突数据的采集和提取、右转车流受到干扰前后速度与过街时间对比分析以及机非冲突速度-距离模型。以现实交通数据为基础,通过软件提取右转机动车与行人和非机动车冲突数据,建立标准统一的冲突数据库,以此为基础对比分析右转车流正常行驶状态和受到干扰情况下通过道路交叉口时的车速和过街时间,并建立右转车辆距离机非冲突点不同位置时所对应不同速度的统计模型。研究结果对右转专用相位设立标准的建立和相应信号配时方案的设计具有一定的工程指导意义。

| Abstract: | The main content of research is conflict between right turning vehicles and pedestrians or bicyclists at the signalized intersection where being no exclusive right-turn traffic phase.The research includes collection and extraction of conflicting data,comparisons of right turning vehicles' speed and passing time with and without disturbance,and statistical model of speed-distance based on conflicting point.Conflicting database was founded on real traffic data,data of confliction were extracted by computer program,speed and passing time of right-turn vehicles were compared based on different conditions,conflicting model of speed-distance was established through statistical analysis.Results can be applied in building criterion of exclusive right-turn traffic phase and corresponding intersection signal control strategies. |
