Travel-Times Analysis can produce biases in Urban Mobility assessments. Conversely, Disutilities Analysis fulfills the requirement to assess Urban Mobility by travel-time, monetary costs, and environmental performance. Thus, an experiment regarding Los Angeles, New York, Atlanta, Austin, and Chicago compares Automobile and Public Transportation Travel-Times with Total Disutilities Cost per Mile. Public Transportation, even with limitations, can be competitive, at least in two cities: Atlanta and New York. The results confirm the broader scope of the Disutilities Analysis in Urban Mobility appraisals.
