公路交通事业的快速推进,为中国的社会经济发展起到了重要的促进作用。但是,时有发生的交通事故导致了人员伤亡,同时还造成了一定经济损失,对社会稳定造成了影响。引发公路交通事故的一项重要原因就在于,一些公路的线形设计缺乏理性,影响了交通安全顺畅。本论文基于交通安全的角度,以双车道公路作为研究对象,针对双车道公路线形与交通安全的关系进行探究。 The rapid progress of highway transportation has played an important role in promoting social and economic development in China. However, frequent traffic accidents have caused casualties and caused some economic losses, which have an impact on social stability. An important reason for causing road traffic accidents is that the linear design of some roads lacks reason and affects the smooth traffic safety. From the perspective of traffic safety, this dissertation takes two-lane highway as the research object and explores the relationship between two-lane road alignment and traffic safety.
