I. INTRODUCTION
The GIS technologies used for the ITS (Intelligent
Transportation System) have been widely studied by many
investigators in recent years. With the rapidly development and
widely application of ITS, GIS-T (GIS for Transportation)
technologies are increasingly urgent demanded. The research
and development of GIS based intelligent transportation
application systems have become a more and more important
research area in ITS. GIS mapping for the intelligent
transportations system is an essential, efficient, and effective
tools for planning and managing transportation information
resources [1,2].
