Abstract:

The Federal Highway Administration (FHWA) historically has supplied registered

vehicle and vehicle miles of travel (VMT) data for use with the National Center

for Statistics and Analysis (NCSA) motor vehicle injury and fatality data.

However, the boom in light truck sales (especially minivans and sport utility

vehicles) did not appear to be reflected in the FHWA registered light truck

numbers. When FHWA's figures for registered cars and light trucks were compared

with R.L. Polk data for these vehicles, large variations were found. The

explanation for the majority of the differences in the two data sources was

different definitions for cars and light trucks. FHWA classifies minivans and

utility vehicles as passenger cars, whereas Polk and National Highway

Transportation Safety Administration (NHTSA) classify these vehicles as light

trucks. Starting with the 1993 Traffic Safety Facts Report, NCSA began using

Polk registered vehicle data for calculating fatality and injury rates per

registered vehicle. Based on the methodology described in this note, total VMT

and fatality rates for cars and trucks as reported by FHWA has been revised.

This revision affects these vehicle types back to 1975. 5 p.
