National Transit Map Routes Compiled from GTFS Schedule Data

Compiled on December 02, 2025, this dataset is a nationwide catalog of fixed-guideway and fixed-route transit service in America. It shows transit routes, which are groups of trips displayed to riders as a single service, compiled using General Transit Feed Specification (GTFS) Schedule data.

Use Cases

• Analyze route alignments and service patterns by combining GTFS files like routes.txt, trips.txt, and shapes.txt.
• Study fixed-guideway transit networks across the United States using the spatial accuracy adjustments made by BTS.
• Map nationwide transit service coverage for fixed-route systems documented in the National Transportation Atlas Database.

Strengths

• Nationwide coverage of fixed-guideway and fixed-route transit service in America.
• Compiled from standardized GTFS Schedule data, ensuring a consistent data structure.
• Spatial accuracy is improved through adjustments using submitted GTFS source data and other public information.

Limitations

• Specific row count, column count, and dataset size are unknown, limiting pre-analysis assessment of scale.
• Relies on the quality and completeness of submitted GTFS feeds, which may vary between transit agencies.
• The description does not specify a temporal coverage range for the transit service data.
