【摘要】 对五叉环形交叉口的信号控制方法进行了研究,给出了基于环道容量约束的信号控制参数优化的模型,模型着重考虑了两个因素:环道容量约束,进口道灯、环道灯相互之间的绿信号协调、红信号协调。利用本文提出的控制模型设计了一个实例的信号控制方案,并通过V ISS IM仿真评价了该信号控制方案,验证了本文提出的控制方法的有效性。更多还原

【Abstract】 The research focuses on the coordinated control of traffic lights on five-leg roundabouts,and puts forward the(optimization) model for the signal control parameters,which,based on the constraint of the circulating lane capacity, also considers the coordinated control of green(red) lights for maximizing the volume of the approach streams and the circulating streams.A signal control plan is designed for an illustration according to the model and is evaluated by VISSIM.The feasibility and the validity of the research are verified by the illustration and its VISSIM simulation results.更多还原
