公路网规划是公路建设的重要环节,指导着公路交通的建设和发展,它对于整个公路交通系统发展的优劣有着举足轻重的作用。系统分析公路交通现状,全面认识存在的主要问题,揭示现有路网基本矛盾,提出适当的改进措施和建设方向,对于制定公路建设发展战略目标有着十分重要的意义。因此,加强和完善公路网规划,进行现状公路网的可持续性评价是完全必要的。以公路交通可持续发展的思想,从公路网规划评价的目的、对象和范围着手,对现状公路网可持续发展评价理论与方法进行探讨。
Highway network planning is an important part of highway construction, guiding the construction and development of highway traffic. It plays a decisive role in the development of the entire highway transportation system. Systematically analyzing the status quo of highway traffic, fully understanding existing problems, revealing the existing basic contradictions of the road network, putting forward appropriate measures for improvement and construction direction, is of great significance for formulating strategic objectives for highway construction. Therefore, it is absolutely necessary to strengthen and improve the road network planning and evaluate the sustainability of the existing highway network. With the idea of sustainable development of highway traffic, this paper starts with the purpose, object and scope of highway network planning evaluation, and discusses the evaluation theory and method of highway network sustainable development.
