Study On Traffic Safety Design Technology Of Though Highway In Villages And Small Towns

With the rapid urbanization, the traffic condition has also undergone tremendous changesof though highway in towns and villages, traditional through highway design exemplar hasbeen unable to meet the growing demand for traffic travel. Therefore, according to the surveyon the G108National Highway in towns and villages segment, research on the road trafficdesign issues of through highway in the towns and villages section. Proposed a reasonabletraffic design techniques to through highway, has an important practical significance.First、second and tertiary highway of through highway villages and towns is the mainbackbone of the regional and even national road network, responsible for major transportationtasks. But through highway become internal traffic artery in the towns and villages, result thecomplexity of the traffic situation. Based on the field survey, summarizes the characteristicsof road traffic accidents over towns and villages, and combine the study at home and abroad,propose the mechanism of traffic accidents, explain the elements of road traffic, people,vehicles, traffic environment in the role of accident. The exposition of the problems in trafficon the three factors of the person, vehicle, traffic environment, provides a basis for targeted toresolve conflicts.According to the existing problems, research on problems according to sections andintersection. Road traffic through the transformation of the cross-sectional form, bus serviceand rate-limiting measures and ways and means to enhance the service capabilities of thesections; Intersection by referring to the advanced experience in the design, accessmanagement based on first Intersection spacing to classify the spacing of each segment, drawa variety of spacing recommended value; combined and then through flexible geometricdesign of the intersection of the main road and the access road and good layout design,intersection series of problems, optimize the towns road traffic order.
