Research on Safety Evaluation Method for Expressway Off-ramp
摘要
Abstract
The safety evaluation method and process of expressway off-ramp were pointed out in this article at first, on the basis of plenty of observation, the evaluation index system was established from the aspects of geometric safety, installation safety and traffic management and control. Using the method of expert consult survey, the weight coefficient of each index was also giVen in this article, and the data obtained from the investigation could be disposed.In order to give the clear definition of different safety condition ,this article used cumulative percentage analysis method;the value corresponding 15% cumulative percentage of safety off-ramp was chosen as upper limit value of common safety, and the value corresponding 85% cumulative percentage of unsafely off-ramp was chosen as upper limit value of unsafely,and the safety level division standard could also be made. Finally,the safety evaluation method established in this article was verified on the basis of investigation of 8 off-ramps.关键词
