MBTA Performance Data
Performance data allows users to analyze how our transit systems are performing based on passenger wait times, travel times between stations, service alerts, and more.
Access to the MBTA-Performance API is no longer available as of May 13, 2024.
Daily MBTA rapid transit performance data is now available from LAMP, our new performance data system, via Parquet files.
Historical data corresponding to most API calls from the retired MBTA-Performance API are also available as downloadable CSVs on the MBTA Open Data Portal at the links in the table below.
