This dataset contains representations of Massachusetts Bay Transportation Authority (MBTA) bus stops for the Summer, 2013 schedule. The layer was developed by the Central Transportation Planning Staff (CTPS) of the Boston Region Metropolitan Planning Organization (MPO). The primary input source was the General Transit Feed Specification (GTFS) shapes, stops and stop-times files produced by the MBTA for each quarterly schedule. The shapes file provides a sequence of point coordinates for each route; the stops file provides the coordinates of each transit stop and station; a sequential list of stops by route was extracted from the stop-times file, which provides scheduled departure times by stop for each trip. The stop lists by route were edited to match those obtained from the MBTA's schedule database. Point feature classes were generated from the shape and stop coordinate files, and their features snapped to Massachusetts Department of Transportation roadway inventory features. Stop points underwent further edits to improve locational accuracy. |
