The Joint Task Force on Safety and Security Certification, established between the Federal Transit Administration (FTA) and the American Public Transportation Association (APTA), prepared this Handbook to support the efforts of the transit industry to achieve continuous improvement in safety and security performance. This Handbook provides a guide for establishing a certification program to address safety and security that identifies the key activities; incorporates safety and security more fully into transit projects; highlights resources necessary to develop and implement a certification program for safety and security; and provides tools and sample forms to promote implementation of the safety and security certification process.
