Evaluation Of Intersection And Driveway Access Engineering Safety

Road construction is an important means of promoting investment in economic growth,the construction and development of all walks of life and is closely related to the highway,the current relevant regulations on the industry involved in road construction part,very complex regulations,a lack of relevant norms highway internal unity,the lack of involved in road engineering safety evaluation criteria for.This gives the road administration department inconvenience to road projects involving regulatory work,but also for road project involving leaving a security technology risks.Highway Intersection is a traffic accident "black spots",in order to ensure road traffic safety,it is necessary to conduct in-depth analysis for road level crossings formula involving road construction,highway traffic safety evaluation in order to meet management needs.This paper reviews the research status on road level crossings formula involving the safety evaluation and assessment method rationality road works;then involved in road traffic engineering characteristics and safety on the road the Cross of formula analyzed in detail,discusses the road Intersection rational geometric characteristic index value for the importance of road safety;then combined based on actual research data gap acceptance theory,proposed highway intersection in minimum security horizon different control mode,the use of modeling and simulation analysis SSAM,amended Highway road project involving level-type minimum value of the crossing angle,while taking advantage of changing lanes with Chi theory supplemented with low-grade highway minimum cross distance index value;on this basis,is proposed based on the analysis of the cause of the accident involving road highway horizontal cross formula safety engineering assessment method,the modeling process and details of the method are described;and the method is applied to the cross of formula involving Yunnan Road Engineering security evaluation Case analysis.This article relates to road engineering safety evaluation management from the roads practical application to road level-style-related road traffic engineering characteristics and traffic safety impact analysis as a starting point to Logit models,gap acceptance theory,sight distance triangle theory,with Chi lane change theory as the theoretical basis,through simulation experiments,field research data analysis techniques,the formula involving highway horizontal cross road engineering safety evaluation reasonable,evaluation methods,etc.were studied in detail.Carding paper from theory to field research data,to simulation and modeling analysis,the level of cross-road formula involving road construction minimum safety line of sight,the smallest crossing angle,the value of the access spacing reasonable proposals,based on analysis of Accidents proposed formula involving cross-road flat road engineering safety level of service evaluation model.We are hoping to cross the road level formula involving traffic safety evaluation of road projects to provide some guidance.
