A Health Impact Assessment of Proposed Public Transit Service Cuts and Fare Increases in Boston, Massachusetts

Abstract

Transportation decisions have health consequences that are often not incorporated into policy-making processes. Health Impact Assessment (HIA) is a process that can be used to evaluate health effects of transportation policy. We present a rapid HIA evaluating health and economic effects of proposed fare increases and service cuts to Boston, Massachusetts’ public transit system. We used transportation modeling in concert with tools allowing for quantification and monetization of multiple pathways. We estimated health and economic costs of proposed transit system changes to be hundreds of millions of dollars per year, exceeding the budget gap the transit authority was required to close. Significant health pathways included crashes, air pollution, and physical activity. The HIA enabled stakeholders to advocate for more modest fare increases and service cuts, which were eventually adopted. This HIA was among the first to quantify and monetize multiple pathways linking transportation decisions with health and economic outcomes, using approaches that could be applied in different settings. Including health costs in transportation decisions can lead to policy choices with both economic and public health benefits.
