Friday, June 24, 2011 - The U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) today expanded its Key Transportation Indicators with the addition of the National Highway Construction Cost Index, a measure of highway construction cost changes since 2003. According to the Federal Highway Administration index, prices related to highway expenditures in the eight-year period from 2003 to 2010 peaked in 2006 before declining, with prices in 2010 slightly above the 2003 level. The new tables bring the total number of transportation indicators tracked by BTS to 23. Indicators are drawn from BTS and other sources to provide timely, easily accessible information for the transportation community. BTS also updated tables that contain information on transportation and the economy, fuel prices, passenger and freight traffic, transportation costs to users, and system performance.
