| 摘 要： | 在对单重与双重信号控制环形交叉口车辆运行特性进行分析的基础上,采用停车线法推导出单重与双重信号控制环形交叉口的通行能力计算公式.其中单重信号控制环形交叉口通行能力分无冲突时间和冲突时间两部分进行分析推导,双重信号控制环形交叉口通行能力是在停车线法基础上考虑了环道空间停放能力而进行分析推导的.然后从通行能力的角度对比分析推导环形交叉口设置不同信号控制方式的条件,并计算出在不同环岛半径、相位绿灯时间以及左转到达率的条件下信号控制方式选择的边界条件,为环形交叉口控制方式的选择提供参考依据.

| Abstract: | Based on the operational characteristics of vehicles at roundabout,the roundabout capacity formula of single and dual signal control were deduced using the stop line ways,in which the single signal control capacity was worked out from no conflict time and conflict time,respectively.Based on stop line way the capacity formula of dual signal control takes the ring road parking capacity into account.Then,the conditions of implementing single or dual signal control from the perspective of capacity are analyzed ... |
