The invention relates to an emergency vehicle priority passing control method for a non-signalized intersection in a networked traffic environment. The method comprises the following steps: step 1, detecting whether an emergency vehicle priority passing demand exists in an intersection communication range or not; 2, emergency conflict areas are determined, and the time interval of an emergency vehicle passing through each emergency conflict area is locked; 3, delineating a network-connected head vehicle on the conflict lane, and optimizing the time interval of the network-connected head vehicle passing through the emergency conflict area; 4, speed induction or track control is carried out on the delineated conflict lane network connection head vehicle; and step 5, after the emergency vehicle passes, the intersection is restored to a first-arrival first-service management strategy. The system is suitable for a whole network connection road traffic environment, that is, whether a manual driving vehicle or an automatic driving vehicle has a networking communication function, can exchange information with a traffic signal control machine, and is very wide in application.
本发明涉及一种网联交通环境下无信号交叉口应急车辆优先通行控制方法,包括如下步骤:步骤一、探测交叉口通信范围内是否有应急车辆优先通行需求;步骤二、确立应急冲突区域,锁定应急车辆通过每一个应急冲突区域的时间区间;步骤三、圈定冲突车道上的网联车头车,优化其通过应急冲突区域的时间区间;步骤四、对圈定的冲突车道网联车头车实施速度诱导或轨迹控制;步骤五、应急车辆通过后,交叉口恢复到先到先服务的管理策略。本发明适用于全网联道路交通环境,即无论人工驾驶车还是自动驾驶车,均具备联网通信功能且能与交通信号控制机交换信息,应用十分广泛。
