Set Continuous Long Downhill Research Highway Safety Facilities

In recent years, with the rapid development of China’s highway, traiffc accidentsare increasing.Freeway continuous long downhill seirous traiffc accident have occurred,has caused widespread concern in the community.In order to improve the continuouslong downhill highway traiffc safety, analysis accident mechanism, a reasonable set ofsystem traiffc safety facilities, a scientiifc integirty transportation security system is themost realistic and effective measures.On the basis of gathering relevant information and research literature, forcontinuous long downhill section of the highway safety analysis, pointing out theimpact dirver, vehicle, road conditions and traiffc accidents environment. Explore thecauses and mechanisms of traiffc accidents，find the current highway safety featurescontinuous long downhill Problems. Continuous long downhill dirver, vehicle, roadconditions and traffic environment and other characteirstics combined highway,continuous long downhill proposed highway safety facilities to set the overall technicaldesign ideas. By analyzing the relationship between the continuous long downhillhighway safety facilities and the number of traiffc accidents between the security of themodel established continuous long downhill highway safety facilities. Downhill safetyfacilities set overall design ideas, including traiffc signs and markings to determine thedesign, geometric alignment design, deceleration fence design, management andservice facilities design, design and other content hedge lane design criteria based oncontinuous long highway. Meanwhile, the establishment of a continuous long downhillhighway safety facilities and systems evaluation model as a continuous long downhillhighway traffic safety facilities set up in accordance with the technical standards andsafety warning. For the pillars to Shanghai and Chongqing high-speed continuous longdownhill section of cold water security design engineeirng facilities, traiffc safetyfacilities make specific safeguards to reduce the incidence of traiffc accidents.This study maximize function continuous long downhill highway traiffc safetyfacilities, protection of the highway smooth continuous long downhill section of roadsafety, and promote the continuous improvement of the long downhill highway traiffc safety situation has very important theoretical and practical significance.
