Using Maps and Online Tools to Operationalize Equity in Shared Mobility Services

Amanda Howell Anne Brown
This project translates research into practice through developing two practitioner-ready tools using findings from NITC project #1401 “Mobility for the People: Evaluating Equity Requirements in Shared Mobility Programs”. In “Mobility for the People,” we confirmed our hypotheses that while many US cities implement shared mobility program equity requirements, specific requirements range dramatically.
