摘要
建立了以绿波带宽度为目标函数、以时差为决策变量的变带速干线协调控制的数学模型。模型中以各交叉口可以为绿波带提供的绿时最大为分解目标,以各交叉口间上下行实测自由行驶时间代替以平均车速计算的交叉口间行驶时间,大大地提高了绿波控制的效率。
This paper builds the mathematic model of variable band speed arterial coordination control.This control objective function is green bandwidth.The control decision-making variable is time difference.In this model,the analyzing objective is to maximize the green time of green band provided by each intersection and to replace the driving time between intersections calculated by average speed by detecting up-stream and down-stream free driving time between intersections.The model can improve the efficiency of the green band control method.
