The Study of the Highway Glare Plate Height under Mixed Traffic

Abstract

At present the highway horizontal curve section of Anti-glare panels with a uniform height, through investigation and analysis, the arrangement of the glare effect is not very good ,under mixed traffic, to analyze the reasonableness of the highway glare plate height,the ighway glare plate heigh of the road sightline safety model is set up , the design speed of 60km / h, 80km / h,anti-glare plate height of model is proven。Concluded，In the combinations of different vehicles，anti-glare plate height ranges between 1.15 and 1.65；By contrasting static line of sight and moving-horizon，in thedifferent velocity, when vehicles travel a critical location, vehicle traffic safety start to receive greater impact. Conclusions can be got,first,vehicles travel in the flat curve sections, according to different traffic, adopt different glare height; When the design speed is 60km / h, if central angle is less than 15 °, vehicles which is traveling on the section is safe; When the design speed is 80km / h, if central angle is less than 30°, vehicles which is traveling on the section is safe.
