直行待行区是提高信号控制交叉口空间资源利用率、提高直行进口道通行能力、降低直行车道车辆排队长度及缓解交叉口拥堵的有效方法。探讨了信号控制交叉口直行待行区的设置条件及其利弊,分析了直行待行区设置前后的直行进口道车辆运行特征。针对直行待行区设置后会增加车辆二次起动-停车而造成的车辆油耗及尾气排放增加等问题,提出了一种以车辆排队长度最短、直行进口道通行能力最大、车辆平均停车率最小为优化目标的交叉口直行待行区时空资源集成多目标优化模型。通过 VISSIM 仿真对该优化模型进行有效性分析,仿真结果表明通过合理设置直行待行区长度,并配以直行相位协调控制策略,能够提高交叉口直行待行区交通运行效益及环境效益。
直行待行區是提高信號控製交扠口空間資源利用率、提高直行進口道通行能力、降低直行車道車輛排隊長度及緩解交扠口擁堵的有效方法。探討瞭信號控製交扠口直行待行區的設置條件及其利弊,分析瞭直行待行區設置前後的直行進口道車輛運行特徵。針對直行待行區設置後會增加車輛二次起動-停車而造成的車輛油耗及尾氣排放增加等問題,提齣瞭一種以車輛排隊長度最短、直行進口道通行能力最大、車輛平均停車率最小為優化目標的交扠口直行待行區時空資源集成多目標優化模型。通過 VISSIM 倣真對該優化模型進行有效性分析,倣真結果錶明通過閤理設置直行待行區長度,併配以直行相位協調控製策略,能夠提高交扠口直行待行區交通運行效益及環境效益。

The waiting-area for through vehicles is an effective way which can increase the space resource utilization and traffic capacity of through approach,decrease the vehicle queue length in through lane and mitigate the traffic congestion at signalized intersection.The setting of criteria and pros and cons of the waiting-area for through vehicles at signalized intersection were discussed,the running characteristics of vehicles which go straight before and after the setting of waiting-area for through vehicles were elaborated.In order to solve the problem of the increase of fuel consumption and exhaust emission caused by the secondary start-stop after the setting of waiting-area,an integrated multi-objective optimization model for the time-space resource of waiting-area for through vehicles was proposed,considering the vehicle queue length,traffic capacity of through approach and average stop rate of vehicles.An efficiency analysis making use of the VISSIM simulation software shows that the proposed model can improve the traffic operation and environmental benefit of waiting-area for through vehicles via setting an appropriate length of waiting-area and choosing a coordinated control strategy for through phase.
