Transportation Services Index and Air, Rail and Freight Indicators, Monthly (BTS)

btsdata/transportation-services-index

Monthly U.S. Transportation Services Index data from the Bureau of Transportation Statistics, one row per month from January 2000: the freight, passenger and total index, airline available seat miles, revenue passenger miles, load factor and enplanements, rail freight carloads and intermodal units, transit, petroleum, natural gas, waterborne, truck and vehicle-miles measures. You choose how many months to return (1 to 100), which end of the series to start from and where to begin. Values arrive as text exactly as the BTS publishes them. U.S. Bureau of Transportation Statistics data, served by Eden Engine; not an official BTS product.
