This is the first Federal Highway Cost Allocation Study (HCAS) since 1982. There are two key reasons for conducting this study. The first is to determine how changes in the Federal highway program and user fees which support that program have affected the equity of Federal highway user fees. The second is to coordinate this effort with the concurrent U.S. Department of Transportation Comprehensive Truck Size and Weight (1997 U.S. DOT TS&W) Study. The 1997 U.S. DOT TS&W Study uses analytical tools developed for this HCAS in estimating impacts of TS&W scenarios on infrastructure, environmental, and other costs and in estimating changes in user fees on various vehicle classes that would reflect changes in highway program costs associated with those scenarios. |
