The invention relates to a lane organization and signal optimization method for an automatic/manual driving mixed intersection. The method comprises the following steps: collecting the number of lanes capable of being deployed at each entrance lane of the intersection, and the passing demands and flow directions of automatic driving vehicles and manual driving vehicles at each entrance lane; establishing an intersection opposite direction entrance lane feasible organization scheme; establishing an intersection optimal period duration and phase green time ratio calculation method; and establishing a heuristic algorithm to realize intersection lane organization and signal scheme optimization. Compared with the prior art, the method supports the design of the intersection automatic driving special lane and the independent phase thereof, and improves the applicability of the intersection lane layout and the signal scheme design in the automatic/manual driving mixed driving mode.
本发明涉及一种自动/人工驾驶混行交叉口车道组织与信号优化方法,该方法包括以下步骤:收集交叉口各进口道可部署车道数量、各进口道自动驾驶车辆和人工驾驶车辆的通行需求及流向;建立交叉口相对方向进口道可行组织方案;建立交叉口最优周期时长及相位绿信比计算方法;建立启发式算法实现交叉口车道组织与信号方案优化。与现有技术相比,本发明支持交叉口自动驾驶专用道及其独立相位设计,提高了自动/人工驾驶混行模式下,交叉口车道布局与信号方案设计的适用性。
