The Green Line ADA Alternatives Analysis focuses on improving ADA accessibility along the surface portion of the Massachusetts Bay Transportation Authority’s (MBTA) Green Line. Foursquare ITP was responsible for evaluating the feasibility of consolidating stations at three locations across the system. As part of the study, Foursquare ITP conducted a walk-distance analysis that quantified the change in walk times across each of the three study areas. The team documented existing conditions and highlighted impacts on residents, employees, community resources, local businesses, and economic justice populations. The final study lists all potential impacts related to consolidation, along with quantifying the net benefit of station consolidation from an accessibility and travel-time standpoint.
