Safety & Security Time Series Data
Contains monthly-updated Safety and Security (S&S) information reported by urban Full Reporters.
Please note that beginning in May 2016, the Safety and Security Time Series will classify data reported to NTD as follows:
The Time Series has always counted injuries and fatalities associated with Suicide events in the Suicide column and recently updated the file to perform the same adjustment for Attempted Suicide events as well. 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. In more recent years (2016 to present), the data available in the NTD regarding Suicides is more precise. Therefore, people who are harmed in a suicide-related event who were not reported as attempting suicide are classified according to the reported Person Type (e.g., Passenger, Employee, etc.) while any person identified as a Suicide or Attempted Suicide is counted in the Suicide column.
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 now 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.
