中文摘要：
为了指引驾驶员快速便捷地到达目的地，拟建立基于双圈覆盖法的兴趣点指路标志布设模型，并对其应用进行探讨。通过分析驾驶员的认知和驾驶习惯，兴趣点的指示区域划分为核心指示区域和外围指示区域，在核心指示区域内实现全路网指示，在外围指示区域进行路径诱导。以广州大学城现有指路标志为实验，同中山大学的指引进行对比，实验结果显示模型不仅能够覆盖大学城主要出入口和骨干路网的交叉口，而且能够实现在核心区域的细致指引，验证了模型的实用性。
英文摘要：
In order to guide drivers to destinations quickly and conveniently, this paper developed a guide sign deployment model for point of interest （POI） based on the double circle covering method. Firstly,it constructed the road guide sign system data model. Based on the analysis of driver＇ s routing choice behavior, it divided the guidance scope into the core region and the peripheral region. Guiding information for POI should be deployed on all junctions in the core region ~ while it should be de- ployed merely on the optimal paths in the peripheral regions. Compared to guide signs which indicate to Sun Yat-sen University in Guangzhou Higher Education Mega Center（ GZHEMC）, the result shows that the deployment model can cover all the en- trances of the GZHEMC and the major junctions in the backbone network. Furthermore, it can realize the detail guidance in the core scope of the indicating POI. Thus,it verifies the practicability of the deployment model.
