| 摘 要： | 分析了常用的基于流量、距离、周期的交叉口合并控制原则,提出了综合因素关联度量化方法,考虑交通流量、交叉口距离、车队离散特性等因素,基于车队离散模型,构建相邻交叉口间关联度的量化公式,建立指标修正公式,结合实际分析模型的可靠性,获得反映综合因素的关联度值,为子区交通信号控制提供是否合并控制的决策支持。采用仿真软件进行模型应用,选择了具有典型意义的700 m相邻交叉口,以及4个交通流平稳上升的时段,进行关联度值计算,并根据是否合并的决策支持调整信号控制参数。结论表明:对于单一原则难以界定的边缘性合并判断,基于车队离散模型的量化综合判断方法能够有效地解决,并为交通信号协调控制决策。

| Abstract: | Correlative measurement between adjacent intersections considering multi parameters is presented after analysis of signal volume,intersection length and signal cycle principles for coordinated control of intersections.Taking account of traffic volume,length and platoon disperse characteristics,the correlative measurement formula of correlative measurement between adjacent intersections is put forward,index modify functions are defined,and the reliability is studied according to real traffic.The calculated c... |
