ArcGIS Pro 2.2 introduces three new geoprocessing tools for working with GTFS public transit data. The new tools, in the Transit Feed (GTFS) toolset in the Conversion Tools toolbox, are: Features To GTFS Stops, GTFS Shapes To Features, and GTFS Stops To Features. These tools allow you to convert the geographic portions of a GTFS dataset into feature classes that can be visualized in a map and used as input for further analysis, and to export edits to your stops back into a GTFS stops.txt file.
The GTFS Stops To Features tool converts a GTFS stops.txt file to a feature class of points using the stop_lat and stop_lon fields to define the stop locations. The GTFS Shapes To Features tool converts a GTFS shapes.txt file to a polyline feature class showing the physical paths taken by vehicles in the public transit system. If your GTFS routes.txt file contains route_color information, the output of the GTFS Shapes To Features tool will be rendered in the color specified there. The Features To GTFS Stops tool converts a point feature class into a GTFS stops.txt file. You can use this tool in combination with the GTFS Stops To Features tool to edit and update your GTFS stops.txt file.
