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].
