2015 Urban Mobility Scorecard
Findings in the 2015 Urban Mobility Scorecard are drawn from traffic speed data collected by INRIX on 1.3 million miles of urban streets and highways, along with highway performance data from the Federal Highway Administration. The 2015 edition provides a comprehensive analysis of traffic conditions in 471 urban areas across the United States. The vast amount of information makes it possible to examine problems in greater detail than before, and to identify the effect of solutions at specific locations.
