GTFS is a data format for transit data which is rapidly growing in popularity. Public transit agencies with GIS capabilities have an interest in publishing data in GTFS format. Seeing and using this data in the ArcGIS environment would be valuable.
Hello, Jeff. We already have some tools to use GTFS data with ArcGIS, available for download here: http://www.arcgis.com/home/group.html?id=d8e84e82803e4c3690c30f9ef0f960fc
These do not use the Data Interoperability Extension, though.
