Transportation Data Sources

There is a wealth of information on transportation on the web, and the volume is expanding rapidly.

The National Repositories

As a starting place for all modes of transportation - land, sea and air - try TranStats at the Bureau of Transportation Statistics.

Transit. Data for transit is far more complete than for the private auto and highways system. The National Transit Database (NTD) provides tables on all aspects of transit operations for nearly all public operators. The operators must provide the data as a condition of receiving federal funds. The data is aggregated to the level of the transit organizations and for whole years, with separate figures for each mode (motor bus, heavy rail, etc.)

Although there is a link from TranStats to the NTD, it seems awkward. The home page of the NTD can be accessed directly via this link.
