Safety Performance Management

The Safety Performance Management regulations supports the Highway Safety Improvement Program (HSIP) and requires State Departments of Transportation (DOTs) and Metropolitan Planning Organizations (MPOs) to establish Safety targets for five performance measures.

1. Number of fatalities
2. Rate of fatalities per 100 million Vehicle Miles Traveled (VMT)
3. Number of serious injuries
4. Rate of serious injuries per 100 million VMT
5. Number of non-motorized fatalities and non-motorized serious injuries

When do MPOs establish Safety Targets?

When establishing Safety targets MPOs may support the state’s targets, or establish their own quantifiable target for the metropolitan planning area. States establish Safety targets and report them for the upcoming calendar year in their HSIP Annual Report that is due August 31 each year. MPOs must establish Safety targets within 180 days of the State establishing and reporting its Annual HSIP Report, no later than February 27 of each year.

How are Safety Targets reported?

States report their Safety targets to the Federal Highway Administration annually in their HSIP report. The Jackson MPO reports its Safety targets annually to the MS Department of Transportation (MDOT).

Safety Target calculations

• 5-year rolling average: Each target is based on a 5-year rolling average
• Roads addressed: Safety targets cover all public roadways within the metropolitan planning area boundary regardless of ownership or functional classification, just as State Safety targets cover all public roads in the State.
• Data sources: A combination of national data sources and a State maintained crash dataset is used to establish Safety targets including Fatality Analysis Reporting System (FARS) and MDOT’s Safety Analysis Management System (SAMS)
