This comprehensive Story Map highlights key concepts and best practices for public transit GIS analysis. It shows how to determine who your transit system serves, how well people are served by transit, and how easy it is for people to access important destinations by transit. The analyses were done using ArcGIS and the tools available on this website. You can also watch a narrated version of this Story Map if you want.
These blog posts describe the tools on this site and best practices with public transit in ArcGIS:
Where to get GTFS data:
Check out the GTFS Best Practices page for tips on how to construct your GTFS datasets.
If you want to build experimental GTFS datasets you can use with these ArcGIS tools to compare different route planning scenarios, I recommend TransLoc Architect.
For detailed lectures and instructions to help you learn how to use these tools recreate the analyses shown in the Story Map above, download the workshop materials and watch the lecture videos from the "Using GTFS Data in ArcGIS" pre-conference workshop at the GIS in Transit 2017 Conference.
