Guide sign system plays an important role in traffic flow guidance. The aim of the paper is to construct a deployment model for urban guide signs. In this study, a model for guide sign is proposed first. It describes the road network and guiding information sufficiently to support the deployment model development. Then, based on the relationship between guide signs and road network topology, guiding information is classified into 2 categories: connection signs and direction signs. The deployment model and its algorithm for guide sign are proposed based on engineering experiential principles. Finally, the guide sign model is applied to Guangzhou Higher Education Mega Center, and the results show that our deployment model is feasible and could contribute to realizing the intelligent management of guide signs. |
