The Security Systematic Research Of Continuous Long And Steep Downgrade Sections

There are a large proportion of continuous long and steep downgrade sections inmountainous highway, it will be easy to have an accident course of brake failure in thelong time driving, brought serious influence to the normal operation of the highwayand the safety of people’s lives and property. Improve the plane and vertical section’sdesign can be avoid vehicle braking out of control in continuous long and steepdowngrade sections, however, Road conditions often limited in mountain area,single-minded perfect road design is unrealistic and uneconomical. In order to ensurethe safety of Vehicles on continuous long and steep downgrade sections, managementmeasures, traffic engineering measures and engineering measures are the majormeasures to solve the traffic safety problem.Through to the analysis of accident、 the driver and vehicle driving forcecharacteristics in continuous long and steep downgrade sections, Combined with theprocess of driving about road conditions, traffic management and security facilities tothe effects of driving safety, EsTablelished integral notion of security design aboutcontinuous long and steep downgrade sections, And then offered the improvement ofroad conditions, the management of overload and speeding, and the set needs ofpassive protection facilities, meanwhile, Combined with dynamic simulation toolsADAMS/Car building the safety simulation system, then analyzed the vehicle drivingsafety evaluation index in different slope, superelevation and running speed, draw thedriving safety advice and the speed limit conclusions in different slope conditions.At last, according to the safety design of baoteng highway, put forward to thesuiTablele security execution system in its continuous long and steep downgradesections.
