  • Changing Access to Public Transportation and the Potential for Increased Travel [supporting datasets]
    McDonald, Noreen ;
    Wolfe, Mary K.
    2020-04-13 | PDF
    With nationwide declines in public transportation ridership, transit may be falling behind in its ability to help cities deal with congestion. Increasing real-estate values are causing the economic displacement of low-income populations, those most closely associated with transit ridership. A plethora of new mobility options are providing alternati ...
