Field notes
The current analysis covers 30 service days across five MBTA rail lines and separates observed travel time from reliability measures. TransitMeter reports 2,767 direct journeys, 123 station reports, and more than 1.27 million stop observations. Its line view combines balanced-arrival percentages, long-gap rates, and a seven-day score change; the Green Line shows the highest long-gap share at 19.4%, while the Mattapan Line leads the displayed ranking at 93/100.
