摘要
高速公路交通事故频发,重、特大事故占比高,对高速公路行车人员的人身安全产生巨大威胁。高速公路设置的诱导装置功能单一,诱导作用不强。基于上述现状,研发一种可实现高速公路拥堵路段车流密度提示、交通事故报警和事故路段交通诱导功能的新型智能光电轮廓标。结合高速公路交通事故疏导理论,对道路拥堵或事故状态下的车流密度与事故影响范围进行计算,并结合高速公路道路服务水平,对事故影响范围内的车辆进行闪烁报警,有效降低高速公路二次事故发生率。
The traffic accidents of expressway are frequent and serious, which pose a great threat to the personal safety of freeway drivers. The function of the guidance device set up on the expressway is single, and the inductive effect is not strong. Aiming at the above problems, a new type of intelligent photoelectric contour was designed, which can carry out the function of traffic flow density warnings, traffic accident alarm and traffic guidance in congested section of expressway. With the traffic accident dredging theory, the traffic density and the influence range of the accident would be calculated under the condition of road congestion or accident. Combined with the level of highway service, flashing alarm for drivers in the range of accidents would be carried out which can reduce the occurrence rate of secondary accidents effectively.
