多雨地区道路平曲线半径及安全限速设置研究
|
摘要
基于道路行车视距的研究,综合考虑雨天影响下的环境能见度、路面附着系数以及道路平曲线半径、横坡值等参数,构建一种适合多雨地区道路平曲线路段的安全限速计算模型。计算结果表明:降雨强度及雨天条件下的低能见度是影响平曲线路段限速的重要因素,依据计算结果,可对多雨地区的平曲线极限半径进行优化设置,同时针对多种降雨强度给出不同平曲线路段对应的限速设计值。
Based on studying road driving sight distance,combining the visibility,coefficient of road adhesion&road horizontal radius,cross slope value and other parameters,this paper forges a road horizontal curve's security rate-limiting calculation model for a rainy area.The result demonstrates that rainfall intensity and low visibility in rainy condition are the important factors to horizontal curve roads rate-limitation.According to the results,it can optimize the setting for horizontal curves limit radius of rainy area.Meanwhile,as to various precipitation,it will deliver different correlated rate-limiting design values in various horizontal curve roads.
