The invention discloses a coordination path chain green wave bandwidth multi-round optimization method. The method comprises the following steps: determining coordination phases of intersections through which all coordination path chains pass and green light starting and ending time points of the coordination phases; according to the number of coordination paths contained in each coordination path chain, determining the maximum round number of green wave bandwidth optimization of each coordination path chain and each round of coordination path set, and determining the maximum round number of green wave bandwidth optimization of the control area; aiming at each round of coordination path set, calculating an upward shift tolerance and a downward shift tolerance of each intersection phase difference of each round, and determining an intersection phase difference adjustment object and an adjustment amount; and outputting a final result of the phase difference adjustment amount of each intersection. The invention provides a method for multi-round optimization of the green wave bandwidth of each level of coordination path chain on the basis of ensuring that the green wave bandwidth in the whole process is unchanged by comprehensively analyzing the up-shift tolerance and the down-shift tolerance of the phase difference of each signal intersection, and can optimize a plurality of coordination path chains in a control area at the same time.

    本发明公开了一种协调路径链绿波带宽多轮优化方法,该方法包括:确定各协调路径链所经过交叉口的协调相位及其绿灯起止时刻点;根据各协调路径链包含的协调路径数量,确定各协调路径链的绿波带宽优化最大轮数及各轮协调路径集,确定控制区域的绿波带宽优化最大轮数;针对各轮协调路径集,计算各轮次各交叉口相位差的上移容许量、下移容许量,确定交叉口相位差调整对象及调整量;输出各交叉口的相位差调整量最终结果。本发明通过综合分析各信号交叉口相位差的上移容许量与下移容许量,在保证全程绿波带宽不变的基础上,提出了一种对各级协调路径链绿波带宽进行多轮优化的方法,可以同时优化控制区域内的多条协调路径链。
