Using GPS capabilities embedded in modern smartphones to measure the quantity and nature of increased mobility that low-cost access to new transportation options provide to low-income mothers, our project will confront the spatial mismatch problem in Allegheny County by expanding the geographic and socioeconomic mobility of our treatment groups. Our research will provide immediate guidance for policymakers seeking to fund practical policy and engineering solutions to spatial mismatch and also support fundamental breakthroughs in the modeling of regional transportation systems.
