城市混合交通流单点自适应控制方法

摘要

为了提升机动车、非机动车和行人在城市交叉口的混合通行效率,分析了机动车、非机动车和行人在交叉口的通行行为与需求,结合交叉口的功能定位,设计交叉口放行优先级的决策方法,在此基础上,提出城市混合交通流单点自适应控制系统的架构和具体算法实现流程.利用VISSIM软件对上述方法的控制效果进行了验证,仿真结果显示交叉口优先通行对象通行效率提升了6.03％,综合通行效率也有明显提升,该方法具有一定的实用价值.%In order to optimize the mixed traffic order of motor vehicles,non-motor vehicles and pedestrians at signalized intersections,an adaptive signal control technique for urban mixed traffic flow at single intersection is developed in this paper. Firstly, traffic behavior and demand of motor vehicles, non-motor vehicles and pedestrians at the signalized intersection is analyzed. Combining with the function of the intersection of positioning, the decision method that determines the intersection release priority is designed.On this basis,the architecture of the adaptive control system of urban mixed traffic flow and the concrete algorithm realization process are proposed.The control effect of the above method is verified by VISSIM software.Simulation results show that the intersection traffic efficiency of preferential object has improved about 6.03％ and the comprehensive traffic efficiency has improved significantly as well.It is proved that this control technique has a certain practical value.
