现今在建或已通车的高速公路中,隧道占总里程的比例越来越高,中长隧道的数量越来越多。长大隧道的交通运输过程中的行驶安全问题日显突出,结合交通运输部提出的打造公路水运品质工程的要求,在隧道交通安全设施中寻求创新应用已势在必行,隧道轮廓反光设施也就应运而生,且应用日趋广泛。
Nowadays, the proportion of tunnels in the total mileage of highways under construction or opened to traffic has been increasing. The number of medium and long tunnels has been increasing. The traffic safety problems of long tunnels have become increasingly prominent. In light of the requirements put forward by the Ministry of Transport for the construction of highways and water quality projects, it is imperative to seek innovative applications in tunnel traffic safety facilities. Tunnel outline reflectors It came into being, and the application is increasingly widespread.
