To better realize the guiding accessibility of guide sign system

the optimization of guide signs deployment is discussed

combining with the existing research. Firstly

the continuous paths and primary paths are defined according to the analysis model for guiding accessibility. Secondly

the algorithm model for optimizing primary path to continuous path is proposed. In this model

two optimization indicators

name as guiding distance and the number of adding guide signs

are defined to decide the selection of extend paths. In the course of searching path

optimization is updated dynamically based on network analysis algorithm

and guide sign information in optimal extend path is added to lead road users to the destination successfully. Finally

the optimization model is tested in Guangzhou Higher Education Mega Center. For a given road

the deployment of guide signs is optimized and all guiding paths are accessible. The result reveals that the algorithm model is feasible and effective.
