SELECTION SUMMARY
도입 판단 요약
Counts of Non-Major Safety and Security Events are reported to the National Transit Database on a monthly basis, by transit agency and transit mode. These include minor fires on transit property requiring suppression, transit worker assaults not involving transport for medical attention, and other safety events that are not reportable as Major Events because a Major Event reporting threshold is not met (see Safety and Security Events dataset for a list of Major Events). This file includes event data reported to the National Transit Database (NTD) for Commuter Rail (CR) and Alaska Railroad (AR) modes, as well as Heavy Rail (HR) service reported for Port Authority Trans Hudson (NTD ID: 20098), Hybrid Rail (YR) service for the Tri-County Metropolitan Transportation District of Oregon (NTD ID: 00008), Hybrid Rail (YR) service for Denton County Transportation Authority (NTD ID: 60101), and Hybrid Rail (YR) service for Capital Metropolitan Transportation Authority (NTD ID: 60048). Because these services fall under the safety oversight of the Federal Railroad Administration, the agencies are not required to report Safety Events (e.g., collisions, derailments, etc.) to the Federal Transit Administration through the NTD. Security events occurring on transit-owned property for these entities are reported to NTD, but excluded from other files to preserve the integrity of those datasets. They are presented in this file for completeness and should be considered by any user attempting to understand the scope and scale of reportable Security Events reported by public transit operators.
