IMPROVED EXPOSURE MEASUREMENTS

A cost-effective procedure is given for estimating vehicle miles of travel (VMT) categorized by driver-vehicle-environment characteristics. The procedure utilizes odometer readings recorded during the state vehicle inspection, numbers of registered vehicles, and supplemental driving exposure information obtained through a mail survey of vehicle owners. A statewide field demonstration of the procedure was successfully conducted in North Carolina. Five-way tables of VMT involving the factors age and sex of driver, vehicle make and model year, time (day vs. night), and place (rural vs. urban) were generated to illustrate how the procedure can provide multi-way tables of exposure.
