The following Open Source tools are available for testing feeds in the GTFS format:
- Use the feedvalidator tool to verify that your feed data file matches the specification defined in this document.
- Use the ScheduleViewer application to see your feed data represented on a map. This is not representative of how your data will look in other applications; it is a basic tool for testing. Examine routes and schedules to ensure that the data feed correctly represents your system.
