Safety & Security Major-Only Time Series Data

Contains monthly-updated Safety and Security (S&S) information reported by urban Full Reporters for Major events only.

Considerations for data users:

  • FTA is now releasing on a monthly basis the source dataset for this file for all events starting in 2014. This file provides a record for each major event reported to the NTD with some details about the event. Please find the dataset here: https://data.transportation.gov/Public-Transit/Major-Safety-Events/9ivb-8ae9 
  • Beginning in May 2016, the Safety and Security Time Series presents injuries and fatalities associated with Attempted Suicide events in the same manner. NTD has also updated 2008 through present year tabs to remove these Suicide and Attempted Suicide events from individual Person Type counts.  Please see the Person Type Notes tab for more information. Both of these classifications are made to retain consistent data definitions from year to year and there are no net changes in total number of events, injuries or fatalities as a result.  
  • The NTD categorizes collisions which do not involve transit vehicles as Not Otherwise Classified (NOC) event type, rather than Collision event type. The Collisions column in the 2008 through present year tabs excludes collisions not involving a transit vehicle, moving these events to the respective NOC column. This results in a net decrease in collisions and an equal increase in NOC safety events. There are no net changes to the total number of events, injuries or fatalities as a result of this adjustment.
  • 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 years.
