摘要: 为降低主次道路容量悬殊的交叉口在过饱和状态下次要道路排队溢出风险,减少次路车辆排队过长导致的不利影响,综合平衡主路优先、排队限制、次路延误等多目标要求,建立了次要道路红灯末期排队模型、道路剩余容量模型和多参数协调信号控制模型,运用多目标遗传算法优化求解。实例分析表明:多参数协调控制方法略微增加交叉口总体延误和主路排队长度,但次路延误则下降了约17%,排队长度下降了约30%~50%。这种控制方法能够充分利用主路容量以控制次路排队长度,有效降低次路排队溢出阻断局域路网交通运行的风险,综合平衡主次道路的交通需求,为应对容量悬殊道路交叉口过饱和状态下主要交通矛盾的转移,提供了一种可供参考的控制方法。

Abstract: In order to reduce the risk of queuing overflow on the secondary road at the intersection under oversaturation where the capacity of the primary and secondary roads were extremely disparity, reduce the adverse effects caused by long queues of vehicles on the secondary road, and comprehensively balance the multi-objective requirements such as priority of the main road, queuing restrictions, and delay on the secondary road, the secondary road red light terminal queuing model, road remaining capacity model and multi-parameter coordinated signal control model were established. And multi-objective genetic algorithm was used to optimize this solution. A case study shows that the multi-parameter coordinated control method slightly increases the overall delay of the intersection and the queuing length of the main road. However, the delay of the secondary road has been decreased by about 17%, and the queue length has been decreased by about 30%~50%. The proposed control method can make full use of the capacity of the main road to control the queuing length on the secondary road, and effectively reduce the risk of secondary road queue overflow blocking the traffic operation of the local road network. Comprehensively balancing the traffic demand of primary and secondary roads, a reference control method is proposed to deal with the transfer of main traffic contradictions under the oversaturation state of road intersections with large capacity gaps.
