Description

Road management should be carried out effectively by using spatial and temporal information. Four-dimensional information is required for storing the historical information in the latest condition. In this paper, the four-dimensional information was defined that three-dimensional spatial information and temporal information are combined. This paper proposed the road management system to collect, accumulate, share, and utilize the four-dimensional information. The system has the functions of spatial data infrastructure, road information models, model library systems, common system interface, common functions, road database, and application system. The functions of representation, simulation and progress management were developed by using the four-dimensional information.
