“This study examined the accessibility to jobs by transit in 46 of the 50 largest (by population) metropolitan areas in the United States. It is the most detailed evaluation to date of access to jobs by transit, and it allows for a direct comparison of the transit accessibility performance of America’s largest metropolitan areas. Rankings were determined by a weighted average of accessibility, giving a higher weight to closer jobs. The calculations include all components of a transit journey, including “last mile” access and egress walking segments and transfers. The study’s report presents detailed accessibility values for each metropolitan area, as well as detailed block-level maps that illustrate the spatial patterns of accessibility within each area. A separate publication—Access Across America: Transit 2014 Methodology—describes the data and methodology. In the future, the data presented in this study will be used to complete additional analyses, published periodically. Upcoming reports in the series will explore more detailed aspects of transit accessibility to jobs, including accessibility of jobs of different wage levels and a comparison with accessibility by car.”
