The invention discloses an intelligent traffic control method for a common intersection in an automatic driving environment, and the method comprises the steps: building a determined region through employing the center of the intersection as the center of the determined region; acquiring vehicle position information and vehicle running state information entering the system in real time; finding out all conflict vehicles and judging conflict types; and determining a first group of conflicting vehicles, calculating system total residence time corresponding to the two alternative schemes, and selecting the alternative scheme with the minimum system total residence time. According to the method, vehicle-road cooperation and automatic driving are taken as technical backgrounds, common bidirectional single-lane intersection traffic control is taken as a research object, the total residence time of vehicles in a system is considered, and a common bidirectional single-lane intersection trafficcontrol strategy considering system requirements and system advantages is provided.
本发明公开了一种自动驾驶环境下普通十字交叉口智能通行控制方法,包括:以交叉口中心为确定区中心,建立确定区;实时获取进入系统的车辆位置信息及车辆运行状态信息;找出所有冲突车辆并判断冲突类型;确定第一组产生冲突的车辆并计算两种备选方案对应的系统总滞留时间,选择其中系统总滞留时间最小的备选方案。本发明以车路协同和自动驾驶为技术背景,以普通双向单车道十字交叉口通行控制为研究对象,考虑系统内车辆的总滞留时间,提出了一种兼顾系统需求和系统优势的普通双向单车道十字交叉口通行控制策略。
