山区双车道公路因超速现象严重,在视距特别是超车视距不能满足驾驶员需要时,极容易发生交通事故。而目前已有针对视距进行检验的诸多方法中,或是理论存在缺陷,或是需要大量计算,很难适用于生产实践。本文在前人对运行视距研究的基础上,避开繁琐冗杂的计算,借助当前流行的道路路线设计软件和三维视景仿真软件,通过完全模拟待建道路全貌,并引入“视距检验车”概念,提出了一种对双车道公路超车视距的实时检测的实际可行的方法。
Due to the speeding phenomenon of two-lane highway in mountainous area, it is very easy to cause traffic accidents when the line of sight, especially the passing sight, can not meet the driver’s needs. At present, there are many methods for inspecting line-of-sight, which are either theoretically flawed or need a large amount of calculation and are difficult to apply to production practice. Based on the previous research on running sight distance, this paper avoids complicated and complicated calculation, with the help of current popular road route design software and 3D visual simulation software, completely simulates the whole road to be built and introduces “ Car ”concept, proposed a real-time detection of two-lane road overtaking real-time method feasible.
