Adaptability Analysis On Traffic Safety Facilities Of Operating Expressway

With the increasing of expressway traffic mileage every year in China, although thetraffic accidents show a downward trend, the situation of traffic safety is still grim. As a partof the road infrastructure, traffic safety facilities play an important role in reducing theaccident rate and severity.The rational installation of traffic safety facilities is an effectiveway to protect traffic safety for operating expressway. Therefore, the adaptive analysis oftraffic safety facilities is necessary.On the basis of amounts of reference materials, this paper proposes the essence andaim of the adaptive analysis on the operating expressway traffic safety facilities. By theresearch methods of theoretical analysis, live investigation and mathematical statistics, thedissertation analyzes the people, vehicle, roads, environment, traffic management and otherfactors which impact on highway traffic safety, and proposes the corresponding measures oftraffic safety facilities. According to traffic safety facilities deficiencies and defects, thispaper researches the relationship of traffic safety facilities and traffic safety. The articlesummarizes the traffic characteristics and adaptability of the continuous downhill section,continuous uphill section and straight section, proposes the improved measures on trafficsafety facilities from the active protection and passive protection.At present the research of adaptation between traffic safety facilities and traffic safetyis less, which is the point of this dissertation. This research is helpful and play an importantrole in the design, management, maintenance and transformation of traffic safety facilitiesin the future expressway.
