| 摘 要： | 采用公交优先控制策略探讨公交站点距离交叉口停车线较近可能导致公交车在交叉口范围内二次停车的问题.采用加权最小二乘法建立了公交站点停靠时间与公交车头时距的线性拟合函数,预测了公交车到达停车线的时间区段;采用绿灯早启和绿灯延长两种策略设计了公交优先控制方案.通过仿真对控制方案的有效性进行了检验,证明该公交优先控制策略能提高公交车辆的运行效率.

| Abstract: | When bus stop is considerably near the intersection,re-stop within the range of the intercourse will be considered.This paper tries to employ priority control system to discuss such sort of problem.Weighted least squares method is adopted to establish linear regression function,indicating the dwell time and headway,and predicting the time when the bus reaches the stopping line.The strategies of early-green and green-extension are adopted to design the prior-controlling strategy.Examples and tests are used t... |
