Transportation Economic Trends
Revenue per Unit of Output
The impact of productivity can be seen through the price charged per unit of output. This page discusses two units of output: (1) freight revenue per ton-mile and (2) passenger revenue per passenger-mile. For modes where users do not typically pay per use, like driving a personal vehicle, data are difficult to obtain and not presented here.
- Air, truck, oil pipeline, and class I rail revenue per ton-mile grew faster in 2018 than the producer price index suggesting an increase in freight transportation costs above inflation.
- Intercity rail/Amtrak passenger revenue per passenger-mile grew faster in 2019 than the consumer price index (CPI) while air and commuter rail grew less than the CPI. The greater growth in intercity rail/Amtrak passenger revenue per passenger-mile suggests an increase in passenger transportation costs above inflation.
