为了实现指路标志系统的智能化管理，以指路标志诱导系统数据模型为基础，提出了基于道路指示等级的指路标志自动布设算法。该算法是以道路交叉口为研究对象，根据指路标志指引信息与路网拓扑的关系，将指路标志指引信息分威连接性标志和方向性标志两种，定义了基于道路指示等级的方向性标志选择规则，并设计了生成方向性标志的算法模型。最后以广州大学城为实验区域，实验结果表明诱导系统数据模型可有效支持指路标志的生成及分析评价。

Abstract： In order to realize intelligence management of guide sign system, this paper proposed an algorithm for deploying guide signs using guide sign data model from the perspective of road guiding levels. The algorithm took road intersection as re- search object, and guide sign information was classified into two categories, namely, connection signs and direction signs ac- cording to the relationship of guide signs information and road network topology, Moreover, the paper illustrated the selection principles of directional signs based on road guiding levels, and constructed deployment algorithm model for directional signs. Finally, a case study was conducted： the deployment model was tested in Guangzhou Higher Education Mega Center. The re- sult revealed that the data model could support the automatic deployment, analysis and evaluation for guide signs.
