高速公路低能见度团雾预警与诱导系统开发研究

Development and Study of Early Warning and Guidance System of Agglomerate Fog in Low Visibility on Highway

针对高速公路低能见度团雾环境的行车安全问题,开发研究团雾环境下行车风险评估预警与诱导系统,通过建立团雾预测预警模型与团雾行车风险评估模型来获得高速公路在团雾情况下发生行车风险的概率,结合风险概率设计诱导系统,开发的系统成功应用于多条高速公路路段,应用结果表明各示范路段同比事故率极大减少,提高了在团雾情况下的出行安全。

Focusing on the traffic safety under the condition of the agglomerate fog in low visibility on the highway,this paper developed and studied an early warning and guidance system of traffic risk assessment in agglomerate fog.Through the establishment of the prediction and early warning model and traffic risk assessment model to obtain the probability of traffic risk of highway in agglomerate fog,combining with the risk probability,the guidance system was designed.This system has been successfully applied to several highway sections,and the application results showed that the accident rate of each demonstration section was greatly reduced,which can improve the traffic safety in the case of agglomerate fog.
