The invention discloses an intelligent control method for a variable guide lane in an intelligent vehicle-road coordination environment. In consideration of two dimensions of time and space, a space-time resource planning model with the maximum green light utilization rate and the minimum lane space occupancy rate as targets is constructed, and the vehicle running process is improved in combination with a vehicle speed induction strategy and a signal cooperative control method. Afterwards, a non-dominated sorting genetic algorithm with an elitist strategy and a fuzzy inference system are combined to solve the model, target adaptation values in a Pareto optimal solution set and a fuzzy set are compared, and an optimal feasible solution based on the lane number and green time ratio limitation is selected; based on an optimization model, a specific intelligent control method and an operation process are provided, and an optimal combination of a lane allocation scheme and a signal timing scheme thereof is obtained. The selection probability of the variable guide lane can be effectively improved, and the problems of flow direction supply and demand imbalance, low utilization rate of the variable guide lane and the like are solved.

    本发明公开了一种智能车路协同环境下可变导向车道的智能控制方法。从时间与空间两个维度考虑,构建了以绿灯利用率最大和车道空间占有率最小为目标的时空资源做目标规划模型,并结合车速诱导策略与信号协同控制方法改进车辆运行过程。之后,利用带精英策略的非支配排序遗传算法与模糊推理系统组合求解该模型,比较帕累托最优解集与模糊集中的目标适配值,选出基于车道数与绿信比限制的最优可行解。依托优化模型,提出了具体的智能控制方法与操作流程,得到车道分配方案及其信号配时方案的最佳组合。本发明能够有效提高可变导向车道的选用概率,解决流向供需失衡与可变导向车道利用率低等问题。
