Safety Performance Measures

The Safety PM Final Rule establishes performance measures for the purposes of assessing fatalities and serious injuries and supports the Highway Safety Improvement Program (HSIP). This rule also establishes a common national definition for serious injuries. The Federal Highway Administration advises state Departments of Transportation to set realistic targets which are based on analysis of trends and projections of future efforts. While TDOT's long-term vision is to eliminate serious injuries and fatalities, it is likely this will be from a gradual decline. Targets consist of 5-year moving averages and are required to be updated annually.
