城市主干路交叉口直行待行区相位差优化模型
|
摘要
合理的直行待行区设置能够减少延误,提高路网的通行能力。针对目前对直行待行区的研究局限在单个路口且因未考虑相位差协调、从而难以使整条主干路达到最佳通行状态的问题,以设置直行待行区的主干道的最小车辆延误为目标,建立了城市主干路交叉口直行待行区相位差优化模型,并采用遗传算法求解延误最小时的最优相位差。最后,结合交通实例进行Vissim仿真,仿真结果证明模型能够有效减少交通延误、提高路网的通行能力。
A reasonable waiting-area setting for through vehicles can reduce the delay and improve the traffic capacity of roads.However,the confinement of recent researches on waiting areas for through vehicles to one single intersection and the lack of taking the coordination of offsets into consideration make it difficult to achieve optimal traffic status of the whole road.To minimize vehicle delay in the main road,an optimal offset model was presented for urban main road intersections with waiting areas for through vehicles.The genetic algorithm was used to solve the optimal offset in order to minimum the traffic delay.Finally,traffic examples combined with the optimal offset are simulated on the Vissim platform.The results show that the optimal offset model can effectively reduce traffic delay and improve the traffic capacity of the road.
