Data Requirements and Data Sources for Transit GIS Applications

摘要

Geographic Information Systems (GIS) have been recognized as invaluableinformation management and decision making tools for public transit planning and management. Many transit properties have made various levels of effort to use GIS in transit planning and operations. This research involves the identification of data needs for various transit GIS applications and possible sources from which useful GIS data may obtained. Possible GIS transit applications, the data needs for these applications, the existing and potential data sources, and other issues related to data quality and maintenance are discussed.
