The application of GIS in transport planning has grown rapidly in recent years. However, most of these applications tend to be confined to simple street mapping, shortest path analysis, and vehicle routing studies. For transport planning and policy evaluation, planners require process information that is beyond the functionality of current off-the-shelf GIS. This paper presents an innovative approach to integrate potential accessibility models in the ArcView GIS environment using Avenue. Using the light rail transit (LRT) project of Singapore, the design principles and implementation of the application are discussed and illustrated.
