摘要
以十字环形交叉口内部各股车流的潜在冲突点和车辆启动形成的启动波为依据,将环形交叉口左转二次控制的绿灯间隔时间转化为环道左转与本相直行之间的绿灯间隔时间、环道左转与下一相位绿灯启亮时差以及两直行相位绿灯间隔时间的组合,提出各个绿灯启亮的时间差以及绿灯间隔时间的计算方法,并将该方法应用于实例计算。论文的研究成果对提高十字环形交叉口左转二次控制效率和提高交叉口运行的安全性具有重要的意义和实用价值。
The interval between phases of roundabout are transformed into three parts, which are intergreen intervals between left-turns in roundabout, the straights in the same phase, and the straights in the next phase.A calculation method for intergreen interval of roundabout is put forward based on the potential conflict pot and starting wave in the intersection. It is applied in Lianban intersection in Xiamen. The result of the study is important to improve the efficiency and safety of roundabout.
