Car and bus green wave cooperative control method for closed road network

The invention discloses a car and bus green wave cooperative control method for a closed road network. The method comprises the following steps: step 1, constructing a car and bus green wave cooperative control model for the closed road network; and 2, determining a green wave cooperative control scheme of the cars and the buses on the closed road network. According to the method, the public period, the intersection phase sequence and the phase difference serve as decision variables, meanwhile, key constraints are relaxed to avoid the situation that no feasible solution exists in the model, and the green wave cooperative control problem of cars and buses on the closed road network level is solved. 本发明公开了一种面向闭合路网的小汽车和公交车绿波协同控制方法，包括以下步骤：步骤1、构建面向闭合路网的小汽车和公交车绿波协同控制模型；步骤2、确定闭合路网上小汽车和公交车的绿波协同控制方案。本发明将公共周期、交叉口相序和相位差作为决策变量，同时松弛关键约束以避免模型出现无可行解的情况，解决了闭合路网层面上小汽车和公交车的绿波协同控制问题。
