高速公路立交段景观构造对雾天行车安全的影响调查

 高速公路是社会经济发展的产物,它的问世缩短了人与人之间的时空距离,为人们的快捷出行和沟通交流提供了巨大的便利,同时也促进了沿线经济的发展,推动了社会的进步。随着经济的飞速发展,高速公路建设也迈入了一条前所未有的快车道,与此同时,发生在高速公路上的交通事故也逐渐增多,其中大雾天气是影响高速公路行车安全的重要因素,因此对雾天状况下的行车安全进行研究尤为重要。以重庆三溪口立交段为实验段,通过在不同功能的地段设置实验点,在大雾天气下对司乘人员行车真实感受进行调查,得出山区高等级公路生态修复及沿线巧妙的景观构造在结合公路线型的情况下对雾天安全行车具有一定的引导作用,有助于降低大雾天气下行车事故的发生率,保证行车安全,为以后大雾多发地区山区高速公路的设计、修建提供帮助。

The Effect of Highway Overpass Landscape Structure on Driving Safety in Foggy Days

The highway is the product of social and economic development, to shorten the temporal and spatial distance between people, by providing great convenience for quick travel and communication, while also promoting the economic development and the progress of society. With the rapid economic development, the highway construction has entered an unprecedented fast lane., The number of accidents occurred on the highway is gradually increasing. The fog weather is an important influencing factor on the accidents. Therefore, it is very important to study the driving safety under foggy conditions .In this paper, experimental points are set on different function areas in Sanxikou overpass segment of Chongqing, to evaluate the driver 's and passenger 's true feelings while driving down the road in the foggy condition. From the experiment, it is found that the ecological restoration & ingenious landscape structure along both sides of the mountainous areas, which matches well with the linear pattern has certain guiding effect on the traffic safety in foggy days, to reduce the accident incidence under a heavy fog condition and to ensure driving safety. The guiding function of the ecological restoration & ingenious landscape structure along highways should be considered in the design and the construction of mountainous area highways in fog-prone areas.
