MBTA Walking Map

The MBTA Walking Map was a experiment in using GIS to analyze the transit "walking shed" of each station in the MBTA network.

Isochronal zones (shown as colored rings) demonstrate that not every station is equally accessible for the walker, due to variations in road networks, sidewalks, and other man-made and natural obstacles. The map holds importance to renters, home buyers, travelers, and businesses looking to see just how long it would take to reach their location from the nearest T stop, including the MBTA commuter rail.
