高速公路主线侧连续出口最小间距研究
Study on minimum distance of the highway line-side continuous export
摘要
Abstract
Taking the highway line side continuous export minimum distance as the research object,this paper es-tabilished the main line side exit ramp straight minimum distance model,on the basis of the characteristics of the driver reading mark,the highway time headway distribution rule and the characteristics of lane changing model. The suggestive values of minimum distance were then obtained based on the lane number and designed speed of ex-pressway mainline side exit ramp.The proposal is a little bigger than the specified value,which is beneficial to in-crease the export accuracy of highway vehicles and guarantee of the highway traffic capacity,reduce highway acci-dent rate.The result provides reference to the settings of the highway exit-ramp in our country,and it concluded that the minimum distance of the highway line-side continuous export is relevant to the number of the lanes.关键词
