TTI's 2010 Urban Mobility Report

This Urban Mobility Report begins an exciting new era for comprehensive national congestion measurement. Traffic speed data from INRIX, a leading private sector provider of travel time information for travelers and shippers, is combined with the traffic volume data from the states to provide a much better and more detailed picture of the problems facing urban travelers. Previous reports in this series have included more than a dozen significant methodology improvements. This year's report is the most remarkable "game changer;" the new data address the biggest shortcoming of previous reports.
