This dataset contains representations of Massachusetts Bay Transportation Authority (MBTA) bus stops for the Spring 2017 schedule. The layer was developed by the Central Transportation Planning Staff (CTPS) of the Boston Region Metropolitan Planning Organization (MPO). The primary input sources were 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 for each transit stop and station. A sequential list of stops for each for each 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 2011 roadway inventory features. Stop points underwent further edits to improve locational accuracy.

Point feature classes were generated from the shape and stop coordinate files, and their features snapped to Massachusetts Department of Transportation 2011 roadway inventory features. Shape points for each route underwent further edits to match the path traversed by the route. A polyline feature for each route was then generated from the shape points using the ArcGIS Points to Line tool. Each polyline feature was converted to a route using the CreateRoute linear referencing tool.
