Long Downhill Linear Safety Design Of Mountain Highway

This item thesis grew up abroad on downhill through traffic safety research analysis,contrast, grew up downhill section to find out common security issues, and proposedmanagement plan to guide the mountain highway alignment design to make possible toavoid its lead after the opening downhill due to growing traffic accidents. At the same time,learn about highway safety research tunnel alignment proposed highway tunnel part of therelevant design recommendations indicators to increase the speed lane road tunnel safety.This paper studies linear downhill safety design methods, depending on theseriousness of the slope analysis system (Grade Severity Rating System) model calibrationresults, the heat test results and brake temperature prediction model test results and vehicledynamics analysis conclusions, mountainous Kew highway downhill slope and slope grewlong portfolio indicators, including: the average longitudinal and overall control of the totalslope length, longitudinal gradient of slope length combinations, gentle slope slope length,inverted slope settings, etc., and thus on the horizontal and vertical linear combination ofsafe design recommendations made. Its purpose and significance of key:⑴Through continuous downhill different load, the speed of large trucks underreal-time temperature measurement test wheels, brakes on the U.S. GSRS temperatureprediction model was tested and corrected；⑵Create a new brake temperature prediction model and optimize the designspecifications proposed Longitudinal；⑶Grew up downhill mountain highway to improve traffic safety section.
