This report contains selected information on toll facilities in the United States that has been provided to FHWA by the States and/or various toll authorities regarding toll facilities in operation, financed, or under construction as of January 1, 2013. The report is based on voluntary responses received biennially. Differences and inconsistencies from previous editions or in the current tables may be due to omissions, corrections of known errors, and/or the introduction of new ones from those responding to the survey. Known reported ambiguities of rural/urban designations are assumed as urban. Corrections will be made pending confirmation by the State or toll authority in question.
FHWA has constructed a national vehicle miles traveled (VMT) forecasting model where future VMT growth rates can be estimated for three major economic scenarios - normal, pessimistic, and optimistic growth. The normal growth scenario represents the most Likely economic outlook reflects IHS' assessment of most probable future trends in U.S. population, employment, capital investment, productivity growth, and aggregate economic output, with stable energy prices. The pessimistic economic outlook reflects slower growth in employment, investment, productivity, and output compared to historical norms, with volatile and generally increasing energy prices. The optimistic economic outlook reflects unusually rapid growth in employment, investment, productivity, and economic output, as well as stable or declining energy prices.
The VMT projection information is updated annually in the month of May based on IHS, Inc.’s spring release of our nation’s long-term economic data.
