Introduction to Safety Performance Indicators and Targets

Through the Public Transportation Agency Safety Plan (PTASP) regulation (49 C.F.R Part 673 (Part 673)), FTA requires transit agencies to implement a Safety Management System (SMS) to manage safety risk, which can help agencies maintain or improve their safety performance.

An SMS generates information to help transit agency management determine whether the agency is meeting its safety objectives. Agency managers leverage information generated from Safety Risk Management (SRM) and Safety Assurance (SA) activities to understand how safety investments impact safety performance. Agencies may develop safety performance indicators (SPIs) and safety performance targets (SPTs) to help them monitor and track safety performance. SPIs and SPTs serve as valuable tools to prioritize resources to address safety risk and monitor how well investments are working.

FTA has developed this introductory guide to help transit agencies develop SPIs and SPTs as part of the agency’s ongoing safety performance monitoring and measurement activities.
