The invention relates to an intelligent intersection management method based on an unmanned vehicle. The method comprises the following steps of step 1, proposing assumptions for an intersection, an intersection control strategy and the unmanned vehicle; step 2, defining a message type of communication and an operation allowed to be executed by a vehicle; step 3, calculating the priority accordingto the driving information of the vehicle and the time for reaching the intersection; and step 4, calculating the occupied time of the intersection resources through the vehicle information, detecting the potential collision, and adjusting the vehicle speed. The method is advantaged in that the ICP protocol is used for managing the passing of the unmanned vehicle at the intersection, and therebythe traffic condition of frequent congestion of a conventional traffic light control strategy is overcome, the waiting time of the vehicle at the intersection is greatly reduced, and passing efficiency of the vehicle is improved, moreover, the influence of factors such as misoperation of a driver and the driving level on safety of the urban traffic system can be avoided by completely adopting an unmanned driving mode.
本发明涉及一种基于无人驾驶车辆的智能交叉路口管理方法,包括如下步骤:步骤1:对交叉路口、路口控制策略、无人驾驶车辆提出假设;步骤2:定义通信的消息类型及车辆允许执行的操作;步骤3:根据车辆的行驶信息,及其到达交叉路口的时间计算优先级;步骤4:通过车辆信息计算交叉路口资源被占用时间,检测潜在的碰撞,调整车速。本发明中,通过使用IICP协议管理无人驾驶车辆在交叉路口的通行,不仅能够克服传统的红绿灯控制策略频繁拥堵的交通状况,极大程度的减少车辆在交叉路口的等待时间,提升车辆通行效率;而且,完全采用无人驾驶方式能够避免司机的误操作、驾驶水平等因素对城市交通系统安全性的影响。
