What does equity mean when we have a caste-based transportation system? Transportation and planning debates around the country increasingly ponder how we rectify long-standing inequities in transportation access that have disadvantaged the poor and people of color.  In Oregon, the Department of Transportation has an elaborate “equitable mobility” effort as part of its analysis of tolling. And Portland’s Metro similarly is reviewing transportation trends to see how they differentially affect historically disempowered groups.

This discussion is fine, and long overdue, but for the most part ignores the equity elephant in the room:  America’s two-caste transportation system.  We have one transportation system for those wealthy and able enough to own and drive a car, and another, entirely inferior transportation system for those too young, too old, too infirm or too poor to be able to either own or drive a private vehicle.  There are other manifest inequities in the transportation system, but most of them stem from, or are amplified by this two-caste system.

Those in the lower-caste face dramatically longer travel times, less accessibility to jobs, parks, schools, and amenities, and face dramatically greater risk in traveling than those in the privileged caste.  In a policy memorandum to Portland’s Metro regional government, we’ve highlighted the role of the caste system, and pointed out that its virtually impossible to meaningfully improve equity without addressing this divide.
