基于多元因素的高速公路可变限速值计算方法研究

A New Method for Determining Variable Speed Limits on Freeway

分析了高速公路限速的影响因素,总结了国内外高速公路限速值计算方法,在此基础上建立基于多元因素的高速公路可变限速值计算模型。该模型综合考虑交通量、道路线形、能见度,路面摩擦系数等因素,克服了静态限速存在的不足。

This paper analyzes the factors affecting freeway speed limit and establishes a variable speed limit model.The model takes several factors into account including traffic volume,road alignment,visibility,surface friction coefficient,etc.The proposed approach can overcome the limitation of static speed limits.
