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
