Impact of light-rail implementation on labor market accessibility: A transportation equity perspective

Abstract

This study seeks to examine transit's role in promoting social equity by assessing the before-after impacts of recent transit changes in the Twin Cities, including the opening of the Hiawatha light-rail line, on job accessibility among workers of different wage categories. Geospatial, descriptive, and regression analyses find that proximity to light-rail stations and bus stops offering direct rail connections are associated with large, statistically significant gains in accessibility to low-wage jobs. These gains stand out from changes in accessibility for the transit system as a whole. Implications of the study results for informing more equitable transit polices are discussed. © 2012 Yingling Fan, Andrew Guthrie, and David Levinson.
