Research On Traffic Safety Safeguard Of Freeway Reconstruction And Expansion Project Construction Process

With current continues and rapidly expanding of our country economy, for adapting the traffic demand of harmonious society fast development,our country highway construction undertaking begin to high speed development.Besides constructing several highways, The original highway also faces the question that they cannot adapt the transportation fast demand which have to be widen as well as the traffic safety safeguard question with constructing. Considered the highway is important for the national economy which plays the transportation aorta's influence role, Guaranteed the transportation to be unimpeded and the traffic safety on the highway extension construction process, the general plan of on the one hand construction on the other hand movement conforms to the country request that save the efficiency and the according development, guaranteed the harmonious society progresses unceasingly and the economical unceasingly healthy development. Article summarized the highway traffic safety influencing factor, the traffic flow characteristic on the highway extension process systematically. According to changes the extension process characteristic, and unifies the highway traffic safety influencing factor, inducted highway safety equipment especially the traffic safety facility on the extension process, proposed the safety equipment design and establishment that adapts the extension construction process in the highway. Research the extension process transportation safety control of the highway, summarizes the feasible effective safety control. Based on this, simultaneously unifies the project example, summarized the road traffic safety evaluation method, the utilization grey theory has been carried on the safety evaluation about the highway extension process traffic safety facility design and the safety control application.Analysis the project example of the highway extension process transportation safety control, that depends on the project example of the extension operation area of Zheng Luo highway Xuchang section, mainly carry on the analysis from these aspects that includes the traffic flow characteristic of the operation area, the extension process traffic safety safeguard mechanism to apply, the traffic safety facility research and so on; Simultaneously the safe analysis appraisal has been carried on, the punishment measure is proposed.Through the discussion and the research of this article, hope to provide the measure for the highway extension process transportation safety control question, and provides the theory basis for the safety equipment establishment research, and lays the foundation for the road safety science appraisal.
