Road Alignment Optimization Based On The Concept Of The Self-explaining And Simulation Evaluation

With the rapid and steady development of our country, our highway constructionis developing fast too, road net have been expanding, the quality of roads is alsocontinuously improved. The consequent number of road traffic accidents ranks high insuccessive years. Traffic safety research has broad practical significance.Based on the analysis of the status of traffic safety, use the gray correlationanalysis to determine the impact of various factors on the weight of traffic accidents,proof speeding is a major factor of traffic accidents. And then focused on the analysisof the status of traffic safety, clear up the phenomenon prone to speeding and theimpact to driver of speeding. Application the self-explaining road concept, analyzeand understand the concept from the mechanism, find out the road safety status of ourcurrent road construction and proposed the basics of the self-explaining roadcombination to our road design works. Use the simulation software VISSIMsimulated the Jingxin highway Jiaoniwan to Jijin province boundary recommend line K26+000to K43+900, Found the shortage of traditional road design based on theevaluation. Optimize the road with the concept of self-explaining road, andre-simulation the road with the VISSIM software. The result show that the use ofself-explaining road concept has greatly improved the traffic safety.The paper research and exploration the traffic safety from the perspective ofspeed control, the use of gray correlation analysis and simulation software VISSIM toevaluate the road is the main content of this paper. Introduce the concept ofself-explaining road to optimization road design is innovative. Provides a newperspective for traffic safety research, has practical significance to enhancing thetolerance of road.
