The invention provides an emergency vehicle priority passing control method in a network connection environment, which can be suitable for emergency vehicle priority passing in various density states, does not need to change lanes for social vehicles, has small influence on traffic operation efficiency, and can effectively guarantee the emergency vehicle priority passing. Comprising the steps of delineating two nearest social vehicles in two lanes in front of an emergency vehicle, and judging whether the social vehicles need to be guided to adjust the speed or not according to the transverse distance between vehicle heads and the longitudinal distance between the heads and the tails of the two social vehicles; if yes, corresponding speed guidance is carried out on vehicles in the delineated society according to the shortest adjustment time and the adjustment speed obtained through calculation, and the emergency vehicles follow the vehicles to run at a low speed; if not, the emergency vehicle gives an alarm normally to realize priority passing; and finally, after the emergency vehicle passes through the two delineated social vehicles, repeatedly judging the speed and guiding until the emergency vehicle drives away from the congested road section, and obtaining the shortest travel time of the emergency vehicle passing through the congested road section.

    本发明提供一种网联环境下应急车辆优先通行控制方法,其可适用于各种密度状态下的应急车辆优先通行,且无需社会车辆换车道,对交通运行效率影响比较小,能够有效保障应急车辆的优先通行;包括圈定应急车辆前方两个车道内最邻近的两辆社会车辆,根据两辆社会车辆的车头横向间距和头尾纵向间距判断是否需要引导社会车辆进行速度调整,若需要,则通过计算获得的最短调整时间和调整速度对圈定社会车辆进行相应速度引导,且应急车辆跟车低速行驶;若不需要,则应急车辆正常警报以实现优先通行;最后应急车辆通过圈定的两辆社会车辆后,再次重复判断速度引导,直至应急车辆驶离拥堵路段,并获得应急车辆通过拥堵路段的最短行程时间。
