The invention provides a vehicle formation control and signal optimization method and system in a networked traffic environment, and belongs to the technical field of intelligent traffic vehicle formation, and the method comprises the steps: obtaining the geometric shape of an intersection, the width of a road, the length of an entrance lane, and the position parameters of roadside traffic equipment; predicting the traffic operation situation of the intersection; performing formation decision on vehicles entering the intersection; real-time signal timing optimization is carried out on the intersection under the multi-constraint condition, the environment, safety and comfort are taken as constraint conditions, the lowest energy consumption and the highest passing efficiency are taken as optimization objective functions, and the economic vehicle speed, the green light display time of all phases and the phase sequence are solved through a rolling time domain dynamic programming method. According to the method, the safety and reliability of traffic operation are ensured while the communication efficiency of the intersection road network nodes is greatly enhanced according to the vehicle formation control strategy and the signal timing coupling optimization mechanism from the microcosmic angle and the macroscopic angle, and the method has practical engineering application value.

    本发明提供一种网联交通环境下车辆编队控制及信号优化方法及系统,属于智能交通车辆编队技术领域,获取路口几何形状、道路宽度、进口道长度、路侧交通设备位置参数;对交叉口交通运行态势进行预测;对交叉口驶入车辆进行编队决策;对交叉口进行多约束条件下实时信号配时优化,考虑环境、安全性和舒适性为约束条件,以最低能耗和最高通行效率为优化目标函数通过滚动时域动态规划法求解得到经济车速、各相位绿灯显示时间和相位顺序。本发明从微观和宏观两种角度依据车辆编队控制策略和信号配时耦合优化机制在极大增强交叉口路网节点的通信效率的同时,保证了交通运行的安全性和可靠性,具有实际的工程运用价值。
