【摘要】 道路网自动建模由于效率高、成本低的优势,受到了众多学者的青睐。目前研究大体上分为两类:一类是通过空间信息技术,提取现有道路网的信息,在计算机上重现已有道路网;另一类是借助计算机图形学知识,生成虚拟道路网。本文主要以第二类为主,并将平面道路网作为讨论对象,对近年来的城市道路网建模方法进行归纳总结。通过对典型方法的分析比较,旨在从一个新的视角,为传统道路规划设计提供参考。更多还原

【Abstract】 Automatic road network modeling has been favored by many scholars because of its high efficiency and low cost. The present research is divided into two categories: one is to extract the information of the existing road network through spatial information technology and reproduce the existing road network on the computer; the other is to use the computer graphics knowledge to generate the virtual road network. This paper mainly focuses on the second category, and takes the plane road network as the object of discussion, and summarizes the modeling methods of urban road network in recent years. By analyzing and comparing the typical methods, this paper aims at providing a reference for the traditional road planning and design from a new perspective.更多还原
