MBTA Gated Station Entries

This file contains the count of unscaled station entries for gated MBTA subway, Silver Line and light rail stations by service date and 30-minute period. To note: A service date is defined as 3:00AM – 2:59AM (2:59AM the next day). An entry is measured as a successful credit card tap, smart card tap, or ticket insertion recorded at a faregate. Entries are unscaled and so do not take into account non-interaction with the fare gate (e.g. children or other free passengers, fare evasion, etc.). Entries are only provided for times when the station is open. Employee taps are included in this data. This data does not represent total ridership at a station. Faregates are held open at times for special events or emergencies and entries are not captured accurately during those times. Files are separated by calendar year for previous years, and by month for the current calendar year. Due to data issues, data is not guaranteed to be complete for any stop or date. The following explanation of "split stations" only applies to those stations in the MBTA system that service multiple rapid transit lines. Since validated gated entries only determine that a person entered a station, it cannot be used to determine the number of passengers that use a specific line in stations that service multiple lines. To adjust for this, we rely on Central Transportation Planning Staff (CTPS) surveys that gather passenger behavior to develop "split factors." These factors determine the proportion of passengers that board each of the available lines in a split station after entry. For example, at Government Center, passengers tap and enter through the main gates and may choose to take the blue line or the green line. According to the surveys, we assume that about 90% of Government Center entrants ride the green line and the remaining 10% take the blue line. For the split stations in this dataset, the entries will show up to one decimal point to account for the factors and reduce rounding error when aggregating. It will also create two rows in the dataset for the station, one for each line. MassDOT/MBTA shall not be held liable for any errors in this data.
