This paper presents an integrated transit-oriented travel demand modeling procedure within the framework of geographic information systems (GIS). Focusing on transit network development, both the procedure and algorithm for automatically generating link and line data for transit demand modeling from conventional street network data using spatial analysis and dynamic segmentation are described. Transit stop digitizing, topology and route system building, and the conversion of route and stop data into link and line data sets are performed. Using spatial analysis, the nearest stops are identified along the associated links of the transit line, while the topological relation between links and line data sets can also be computed using dynamic segmentation. A small test network is adopted to demonstrate the process and the results. The advantages of this approach are discussed. This procedure will be useful to many cities and regional transit agencies in their transit demand modeling process within the integrated GIS-based computing environment.
