Abstract

The once relatively obscure statistic of vehicle miles of travel has taken on a much higher profile with the advent of air quality standards and energy policies. It is probable that federal agencies such as the U.S. Departments of Transportation and Energy and the Environmental Protection Agency will use statistics on vehicle miles of travel in establishing future national transportation policies. In late 1977, recognizing the need for a uniform method of calculating estimations of vehicle miles of travel, the Georgia Department of Transportation contracted with the Federal Highway Administration to test the draft procedural manual, Guide to Urban Traffic Volume Counting. This paper outlines Georgia's testing procedures and presents a comparison between procedures in the Guide and the current method of calculating vehicle miles of travel. Statistical tests are reported, and the advantages and disadvantages of each methodology are evaluated.
