Transportation Economic Trends

Cost of Transportation:

Costs Faced by Households

Households pay for travel in two ways, as presented on this page. First, they pay to own and operate passenger vehicles for their own use. Second, they pay fares to use for-hire passenger transportation services (e.g., air, transit bus, and rail services) for their intercity and intracity travel. For total household expenditures on transportation see Household Spending on Transportation.
2018 Year-in-Review
On average, except for air fare, consumers faced higher transportation prices in 2018 than in 2017.

Costs Faced by Households
The Consumer Price Index (CPI) measures transportation costs from the households’ (also known as consumers’) perspective. The CPI is a measure of the average change over time in the prices paid by urban consumers for a market basket of goods and services. The CPI also includes user fees (e.g., water and sewer service) and sales and excise taxes paid by the consumer. Economists often use the CPI as an indicator of general price trends. CPIs for goods and services, such as ones related to transportation, show changes in prices for those goods and services.
The CPI provides a picture of the relative change in the price households pay for transportation. Fare data, shown below, and fuel data reflect the actual price paid. 

The relative change in the price households pay for public (e.g., airfare and transit) versus private transportation (e.g., motor fuel) at times diverge, with significant differences across items.

Transportation Fares
Aviation fares
Airfare reflect both the cost of fuel and competition among carriers. Airfare, shown below, does not include baggage or reservation fees, which airlines began to charge in 2008.
Intercity railroad fares
Amtrak intercity railroad fares represent a complex interaction of demand, operating costs, government subsidies, and regulation.
Commuter railroad fares
Commuter rail includes railway passenger service that operates between a central city and adjacent suburbs. It excludes intercity rail service, such as Amtrak, except for the part of service operated by or under contract with a public transit agency for predominantly commuter services. “Predominantly commuter service” means that, for any given trip segment between two stations, more than 50 percent of the average daily ridership makes a return trip on the same day. Commuter rail does not include heavy rail transit or light rail/streetcar transit service.
Transit fares
For the years 1995 to 2001, BTS calculates average transit fare per trip as total passenger fares by total passenger trips collected by the American Public Transportation Association. For the years since 2001, data come from the National Transit Database, which presents average transit fares per unlinked trip. This means that if a passenger takes a bus with a fare of $1 and transfers to a subway with a fare of $2, the journey would count as two unlinked trips with an average fare of $1.50.

Bureau of Transportation Statistics
The Bureau of Transportation Statistics, part of the U.S. Department of Transportation, is the preeminent source of statistics on commercial aviation, multimodal freight activity, and transportation economics, and provides context to decision makers and the public for understanding statistics on transportation.
