摘　　要：为了合理而准确地描述指路标志信息,提出了面向指路标志标识系统的车道级路网数据模型。从指路标志项、指路标志牌以及指路标志点等3个层面描述了指路标志信息,并建立了三者的数据存储结构。最后,在GIS平台上将上述研究成果应用于珠江新城路网,实现了珠江新城指路标志的自动显示以及对布设方案的定量评价。The contents of guide signs are closely related to the topology of road network.The lane-based road network data model was proposed for road guide signs system.The guide information of road guide signs was described from three levels,which were road guide signs item,road guide signs panel and road guide signs point.Finally,the above-mentioned research product was applied to Zhujiang new town road network.And the road guide signs automatic display and the calculation of quantitative index evaluation for guide signs layout scheme were realized.
