By volunteering to participate, Intercity Bus Atlas (ICBA) Service Providers (Providers) empower the Bureau of Transportation Statistics (BTS) to study and demonstrate the essential role of the intercity bus industry to the nation's transportation system and its ability to enhance American lives by linking them to family, work, education, healthcare, leisure, and more. 

Providers opt-in to the ICBA by completing the Intercity Bus Atlas Registration Form. Submitting the form enters the Provider into a one year agreement with BTS.  The agreement automatically renews until BTS receives a termination request, which Providers must send to NICBA@dot.gov.

The agreement, based on a Creative Commons Attribution Non-Commercial License, permits BTS to collect, compile, publish and archive the Provider's GTFS data at least once a year but no more than four times a year.  The agreement compels BTS to attribute the data to the Provider, prohibits commercial use of the data, and disallows substantive material alterations to the data (i.e., BTS does not impute or replace missing or invalid data from a Provider's feed). 

The data collected are historical snapshots of American bus services. The data are not intended for trip planning, scheduling, navigation, or any real-time or near real-time use by passengers, transportation operators, service Providers, or transportation planners.  Using the data for research, analysis, and planning is permitted and encouraged, while commercial and all other reuses of the data are prohibited.
