传统的干道协调控制模型均以路段的平均速度或设计速度为前提设计绿波协调控制方案,但路段实际车速受驾驶员行为、车辆汇入汇出、公交车进出站台等因素影响,往往无法用单一的数值去衡量,实际速度应有一定的波动区间.论文以传统的混合整数线性规划模型为基础,通过分析路段最小速度和最大速度对带宽的影响和要求建立了基于路段速度区间的干道协调控制模型,并通过与其它两种主流方法进行对比说明了模型的有效性.最后,通过仿真验证说明在路段速度处于一定的区间时该模型优化得到的控制方案对车流的排队长度、延误时间和停车次数有显著的改善.
The traditional coordinated control model of the arterial roadway all designs the green-wave coordinated control scheme based on the average speed or design speed of the road sections. However, the actual speed of the road section is often impractical due to the driver’s behavior, the remittance of the vehicles, the arrival and departure of the bus and other factors A single value to measure the actual speed should have a certain range of fluctuations.This paper based on the traditional mixed integer linear programming model, through the analysis of the minimum speed and maximum speed on the bandwidth of the impact and requirements of the establishment based on the link speed section of the road coordination Control model and compared with the other two mainstream methods to illustrate the effectiveness of the model.Finally, simulation results show that the optimal control scheme of the model has better performance in terms of queuing length, delay time and There has been a significant improvement in the number of stops.
