A new report from CEOs for Cities discusses how the Travel Time Index (a ratio of peak congested travel times to uncongested travel times along a roadway used in the Texas Transportation Institute’s Urban Mobility Report and a widely used measure to compare congestion between cities and support road expansion projects) is misleading as a mobility measure. The Driven Apart report looks at total peak travel time instead, and discusses both congestion and travel distance as the determining factors. As a result, shorter travel distances and the urban form enter the discussion of alleviating peak travel congestion.
Both the San Francisco-Oakland-Fremont and San Jose-Sunnyvale-Santa Clara metropolitan statistical areas show fewer hours of congested travel and rank better on the list of most-congested cities in the Driven Apart report compared to the Urban Mobility Report.
