Congestion growth continues. The 2019 Urban Mobility Report provides a comprehensive analysis of traffic conditions in 494 urban areas across the United States. The report points to the need to consider a full range of mobility improvement strategies. TTI’s 2019 edition uses crowdsourced data from INRIX on urban streets and highways, along with highway inventory data from the Federal Highway Administration. The report was sponsored by the Texas Department of Transportation.
