Measures
| Measure | What it measures | Unit |
|---|---|---|
| Licensed drivers | Total licensed drivers, from FHWA Highway Statistics table DL-1C. | people |
| Motor vehicle registrations | Registered motor vehicles by category (Auto, Bus, Truck, Motorcycle) and, from 2000 on, by private/public ownership, from FHWA Highway Statistics table MV-1. | count |
| Vehicle miles traveled | Annual vehicle miles of travel by rural/urban area and functional road system, from FHWA Highway Statistics table VM-2. | miles |
| Traffic fatalities | Persons killed in motor vehicle crashes by rural/urban area and functional road system, from FHWA Highway Statistics table FI-20. | count |
| Public road mileage | Public road length by rural/urban area and functional road system, from FHWA Highway Statistics table HM-20. | miles |
Caveats
- Vehicle miles traveled (VM-2) is an estimate from each state's own travel monitoring program, not a direct count.
- Traffic fatalities (FI-20) are Fatality Analysis Reporting System (FARS) counts as FHWA republishes them by functional system.
- Vehicle registrations (MV-1) count registered vehicles, not owners; one business or agency vehicle counts once regardless of drivers.
- The licensed-drivers table (DL-1C) starts in 2010 in this republication; earlier years are not available through this source.
- No source table prints a state total for its category breakdown; a state total here is summed from the categories.
- Puerto Rico appears in the source tables but is excluded here; it is not in this site's geography list.
