Abstract: In order to realize the intelligent management of road guide signs, a method of visualization of road guide sign panel based on the flexible combination of guiding information was proposed. As a consequence of analysis for structures of guide sign panel, the message on the guide sign panel was decomposed into guiding information, and then visualization function was proposed. The panel style was determined by the physical and logical topology of guiding intersection dynamically with the help of guide sign system database. Then the composition of geography information and guiding information was utilized in the process of visualization. The visualization method was tested in the Guangzhou Higher Education Mega Center, and the visual panels created by the method shared the most widely features with guide panels in reality. The result reveals that the algorithm is feasible and effective.

Key words: intelligent transportation, guide sign panel, guiding information, visualization
