The invention provides an expressway lane level guiding method and device under an agglomerate fog condition, and the method comprises the steps: obtaining a visibility value and the driving information of a vehicle in real time for the vehicle which is about to drive into an agglomerate fog burst section and is passing through the agglomerate fog burst section; a vehicle operation safety speed estimation model under the low-visibility condition is adopted to estimate and obtain a vehicle suggested operation speed and a safety vehicle distance which guarantee vehicle operation safety; determining the running safety level of the vehicle by adopting a vehicle running safety judgment model under different visibility conditions; and executing a corresponding vehicle management and control strategy on the vehicle, and carrying out multi-mode cooperative lane-level driving safety active induction on the vehicle, so that the vehicle i safely and efficiently passes through the agglomerate fog burst section. Accurate intervention and active guidance of the road traffic flow operation state are achieved through the photoelectric technology, road section front early warning and lane-level active guidance under the agglomerate fog condition are achieved, and the road vehicle operation safety and the road passing efficiency are effectively improved.
本发明提供一种团雾条件下高速公路车道级引导方法及装置,包括:对于即将驶入团雾突发区段以及正在通过团雾突发区段的车辆,实时获取能见度值以及车辆的行车信息;采用低能见度条件下车辆运行安全速度估算模型,估算得到保证车辆运行安全的车辆建议运行速度以及安全车距;采用不同能见度条件下车辆运行安全性判定模型,确定车辆的运行安全性等级;对车辆执行对应的车辆管控策略,以及对车辆进行多模式协同的车道级行车安全主动诱导,使车辆i安全高效通过所述团雾突发区段。本发明利用光电技术实现对道路交通流运行状态的精准干预和主动引导,实现团雾条件下路段前方预警、车道级主动引导,本发明有效提升道路车辆运行的安全和道路通行效率。
