| 摘 要： | 针对目前交通路网中出现的越来越多的非平面路网情况,从构建指路标志系统的需要出发,提出基于复杂结点的面向指路标志系统的非平面路网数据模型,并给出非平面路网拓扑关系的建立方法.将这种数据模型应用于广州市城市路网的指路标志系统中,实现了城市路网中非平面路网上指路标志的自动生成.

| Abstract: | There are more and more non-planar road networks in the traffic networks.From the need of constructing guiding sign system,a new non-planar road data model based on complex node for guide sign system was created.Meanwhile,the method to create the topological structure of non-planar road network was given.The urban guiding sign system built on the above data model was illustrated as an example.This data model is feasible and effective. |

| Keywords: | guiding sign system road network data model complex node layered topology |
