面向指路标志系统的非平面交通路网模型
Non-Planar Network Data Model for Urban Road Guide Sign System
摘要
Abstract
Based on the non-planar road network data model, dividing the road elements into two categories, every section of a road network, such as viaducts and ramps in interchange, was correctly expressed. The topology of roads was also described. The relationship of each node and its adjacent nodes or reaching nodes was built up, and the traffic rules was added to put forward a non-planar traffic road network data model for road guide sign system. The model was applied in the interchange road guide sign system of Guangzhou, and the automatically building of road guide signs was achieved.关键词
