摘要： 路网布局是公路网规划的一项重要内容和环节，布局的评价已经形成一些较为成熟的理论和方法，这为我国公路网规划的发展，乃至对我国公路交通建设起到了重要的作用.随着对公路网规划认识的深入，国内一些专家和学者对路网布局和结构提出了很多新的认识和具体方法，“分形几何学”作为一种新兴学科已经在国民经济各行业得到了广泛的应用.本文分析了现有公路网布局评价指标体系，提出基于分形几何学的评价指标——覆盖度，并进行定量的关联分析.

关键词: 公路网布局, 分形几何学, 覆盖度, 关联分析

Abstract: Highway network layout is an important content and tache of highway network programming. The theories and methods to evaluate of highway network have developed more mature than before which is very important to the development of highway network programming，even to the construction of highway and traffic of our country. With going deep into the recognition of highway network programming, some domestic experts advanced many new insights and specific methods about highway network layout and structure. "Fractal geometry" is having been broadly used in many country economy departments as a new subject. This paper analyzes current highway network layout evaluation index system. The evaluation index of cover degree is presented based on fractal geometry and correlative analysis is made in quality.

Key words: highway network layout, fractal geometry, cover degree, relational analysis
