三维视距在道路设计中已经起着越来越重要的作用,很多科学家正在进行此方面的研究。但是因为其计算方法比较复杂,目前还没有很大的进展。为了对三维视距进行更好的研究,本文总结了前人研究的成果,综述了三维空间视距的计算方法,为以后的空间视距研究以及更趋于安全合理的道路设计提供了依据。
Three-dimensional line of sight has played an increasingly important role in road design, and many scientists are conducting research in this area. However, due to its complicated calculation method, no great progress has been made so far. In order to make a better research on 3D horizon, this paper summarizes the achievements of previous studies, summarizes the calculation method of 3D horizon, and provides the basis for the future study of space horizon and the more rational and safe road design.
