Recent changes to this file by release:

Release Month Change Summary Years in File Affected More Details for Data Users
April 2024 The Status column within each tab has been updated to show the status of the specific Mode and Type of Service rather than the status of the NTD reporter.  ALL YEARS Mode and Type of Service status will be more precise than Reporter Status and will allow users to understand when null values in a month/year column are due to a mode ending service. Generally, a reporter with no active modes can be considered inactive.

File Summary: Contains monthly-updated service information reported by urban Full Reporters. The data in this file is current as of February 29, 2024. This data release includes data values which differ from the Raw Database Time Series (no adjustments or estimates) as follows:

  • Adjustments to historical data (report year 2002 to 2011) for specific agencies which changed data collection methodology and required data adjustments as a result (see Read Me tab for details).
  • Estimates for recent months where no data is reported by an active NTD reporter (i.e., an estimate due to delinquent report submission). These estimates are based on mode-level ridership growth estimates developed by FTA. The strength of each estimate improves when the population of agencies reporting in the prior period is larger. 

This file will be updated periodically by FTA to include data for subsequent months, and to incorporate revisions to prior months in the calendar year made by the transit properties. In some cases, this may include revisions to data from previous report years.
