TTI URBAN MOBILITY SCORECARD 2015 Report Presented by: Keith Nichols, PE Principal Transportation Engineer, TTAC Agenda Item #14 October 7, 2015
INTRODUCTION The TTI Urban Mobility Scorecard report evaluates mobility levels and traffic congestion in all 471 metropolitan areas throughout the U.S. TTI determined mobility levels using INRIX roadway speed data as well as traffic counts and roadway characteristics collected from FHWA s Highway Performance Monitoring System (HPMS). The report includes various recommendations to reduce and manage congestion. The Urban Mobility Scorecard report is available on TTI s website at http://mobility.tamu.edu 2
MEASURES REPORTED Hours of Delay Travel Time Index Freeway Planning Time Index Excess Fuel Consumed Congestion Costs 3
LARGE URBAN AREAS TTI defines 31 urban areas as large (with populations of 1-3 million people), whereas HRTPO uses 36 large MSAs. Portland Sacramento Salt Lake City Denver San Jose Las Vegas Riverside-San Bernardino Oklahoma City Minneapolis- St. Paul Kansas City Milwaukee St. Louis Memphis Indianapolis Louisville Cleveland Nashville Columbus Cincinnati Pittsburgh Charlotte Baltimore Richmond Providence Hampton Roads Austin San Antonio Tampa Bay Jacksonville Orlando 4

STUDY CRITIQUES The Urban Mobility Scorecard only focuses on drivers and fails to account for commute mode share. The report compares peak-period conditions to freeflow speeds. TTI looks at roadway congestion levels, but does not take into account the actual commute time and average commute trip length. Chicago Travel Time Index = 1.31 Atlanta Travel Time Index = 1.24 10
