The invention discloses an intelligent traffic light intersection efficient passing method based on vehicle-road cooperation. The method comprises the steps that BSM information of all vehicles within a preset range from an intersection of a road section is collected through intelligent traffic light roadside equipment; filtering irrelevant vehicles according to the BSM information; after irrelevant vehicles are filtered, calculating the traffic flow density of the road section about to pass through the traffic light intersection within a preset range from the intersection, and dividing the traffic flow density into a first lane traffic flow rho1 and a second lane traffic flow rho2 according to lanes; the rho1 and the rho2 are compared with a traffic flow density threshold value pref, and when the rho1 is larger than or equal to rhoref or the rho2 is larger than or equal to rhoref, it is judged that the corresponding lane intersection is a congested intersection; and when a congested intersection exists, the rho1 and the rho2 are compared, and the green light duration of the road with the large traffic flow density is increased according to the traffic flow density of the two lanes. According to the invention, the traffic efficiency of the vehicle at the intersection is improved, the fuel efficiency is also improved, and the traffic safety is also ensured.
本发明公开了一种基于车路协同的智能红绿灯路口高效通行方法,包括:通过智能红绿灯路侧设备采集该路段距离路口预设范围内所有车辆的BSM信息;根据BSM信息,过滤无关车辆;过滤无关车辆后,计算该路段距离路口预设范围内即将通过红绿灯路口的车流量密度,按照车道将车流量密度划分为第一车道车流量ρ1和第二车道车流量ρ2;将ρ1,ρ2分别与车流量密度阈值pref比较,当ρ1≥ρref或者ρ2≥ρref时,判断对应车道路口为拥堵路口;当存在拥堵路口时,比较ρ1和ρ2大小,根据两条车道的车流量密度大小来增加车流量密度较大的道路的绿灯时长。本发明提高了车辆在交叉路口的通行效率,以及燃油效率也得到了提高,同时也保障了通行安全性。
