Using GIS for Public Transit Planning and Operation
Defining Issue: A public transportation authority operates under federal, state, and internal laws and guidelines. Meeting these requirements takes detailed planning based on high-quality demographic and ridership data, and an accurate street network. GIS Solution: The Regional Transit Authority and Texas A&M University, Corpus Christi, have worked together for three years to provide an accurate basemap, and to develop and integrate census and demographic information, and to program tools for specific analysis of transportation patterns. The solution will soon be extended to cover position monitoring and automated data collection. Methodology: The RTA-GIS uses census data at the block level and ridership data on routes to determine areas of service need and to certify that existing services meet the service requirements. Buffer dynamic routing requests are analyzed using specialized programs to determine where cost savings can be obtained through conversion to fixed route services and fixed route
modifications. A "demand" model is being developed to better design routes using multiple criteria. Software: Esri's ArcInfo, ArcView, Avenue, and Borland Paradox are used.
