MAP-21: Safety

The U.S. Department of Transportation has issued two interrelated final rules governing traffic safety and safety oriented performance management which became effective on April 14, 2016. These two rules are referred to in this folio as:
  • Rule #1 - Safety Performance Measures rule; (23 CFR §490)
  • Rule #2 - Highway Safety Improvement Program (HSIP) rule; (23 CFR §924)
Both final rules relate to highway safety, the primary objective being to significantly reduce fatal and serious-injury crashes on all public roads. The Safety Performance Measures rule (Rule #1) also includes the goal of reducing traffic fatalities of and serious injuries to people using non-motorized transportation modes, namely bicyclists and pedestrians.
MAP-21 Safety Rule #1 requires all State Departments of Transportation to report targets and performance with respect to the following safety performance measures:

Number of fatalities per 100 million vehicle miles traveled (VMT)
