Study On Design Of Traffic Sagety Facilities

As road infrastructure, traffic safety facilities are playing important role on traffic safety. Designing traffic safety facilities should be based on traffic engineering, people oriented, road and economic status so that the traffic safety facilities are of avail.By the study on staus quo of researching and application of traffic safety facilities home and abroad, this paper has analyzed and concluded the fundamental and classification of the subsystems of traffic safey facilities including traffic sign, traffic marking, safety barrier, isolated-closed facility, anti-dazzle facility, sight guidance facility. The designing theories of these subsystems such as placing principle, designing criterion and structure have also been researched.Traffic safety facilities are developing so fast that varied productions of safety facilities had been invented. According to the developing hotspot, the designing methods of vibration line, w-type beam safety barrier and prominent pavement sign have been presented.Lastly, the designing theories of traffic safety facilities which had been concluded are put into practice. That is the traffic safey facilities design on the north-strech part of Guangzhou new international airdrome expressway in construction phase.
