摘要: 从城市功能分区出发,提出利用有限元网格划分思想,结合城市各分区中的道路 特点对城市区域进行剖分,形成城市的支路网。根据城市规划知识中对各等级道路的性质及道 路间距,从已生成支路网中定义并提取出城市主干路和次干路,最后完成对城市各等级道路网 的过程式建模研究工作。该方法将城市路网的分级建模与城市土地利用、功能分区和各等级路 网性质结合,使之形成的城市道路网更符合实际城市规划中对道路网的要求。

Abstract: Considering the functional region in urban, we present a road modeling method based on the algorithms of finite element mesh and road feathers in city district. In our method, urban planning theory is used to build hierarchical road and the trunk roads can be defined and extracted from the branch roads. This experiment combines the road level, land utilization, functional region and characteristic of the road in urban, and shows reasonable result compared to road networks in urban planning.
Key words: modeling of road networks, finite element, functional region, road level
