Safety Performance Measures

Five Performance Measures
Number of Fatalities
Rate of Fatalities per 100 million VMT
Number of Serious Injuries
Rate of Serious Injuries per 100 million VMT
Number of Non-motorized Fatalities and Non-motorized Serious Injuries
Number of Fatalities:

The total number of persons suffering fatal injuries in a motor vehicle crash during a calendar year.

Rate of Fatalities:

The ratio of total number of fatalities to the number of vehicle miles traveled (VMT, in 100 Million VMT) in a calendar year.

Number of Serious Injuries:

The total number of persons suffering at least one serious injury in a motor vehicle crash during a calendar year.

Rate of Serious Injuries:

The ratio of total number of serious injuries to the number of VMT (in 100 Million VMT) in a calendar year.

Number of Non-motorized Fatalities and Non-motorized Serious Injuries:

The combined total number of non-motorized fatalities and non-motorized serious injuries involving a motor vehicle during a calendar year.

Data Sources

Fatality Data: Fatality Analysis Reporting System (FARS). Final FARS data is to be used if it is available, otherwise FARS Annual Report File (ARF) data may be used, which is generally available one year before Final FARS data.

Volume Data: State VMT data is derived from the Highway Performance Monitoring System (HPMS). Metropolitan Planning Organization (MPO) VMT, if applicable, is estimated by the MPO.

Serious Injury Data: State motor vehicle crash database. Agencies must use the definition for "Suspected Serious Injury (A)" from the MMUCC, 4th edition by April 15, 2019. Prior to April 15, 2019 agencies may use injuries classified as "A" on the KABCO scale through use of serious injury conversion tables. However, agencies are encouraged to begin using the MMUCC, 4th edition definition and attributes at the beginning of 2019 for a complete and consistent data file for the calendar year.

Number of Non-motorized Fatalities and Non-motorized Serious Injuries: FARS and State motor vehicle crash database. The number of non-motorized fatalities is the total number of fatalities with the FARS person attribute codes: (5) Pedestrian, (6) Bicyclist, (7) Other Cyclist, and (8) Person on Personal Conveyance. The number of non-motorized serious injuries is the total number of serious injuries where the injured person is, or is equivalent to, a pedestrian (2.2.36) or a pedalcyclist (2.2.39) as defined in ANSI D16.1-2007.

What You Need to Know About Establishing Targets

States:
Coordination and Collaboration:
MPOs:

Table. For each performance measure listed, table indicates state target, which is broken out into the target reported in HSIP annual report for FHWA and the target reported in the highway safety plan for NHTSA, as well as the MPO target.

Example Target Calculations

5-Year Rolling Average: Each target is based on a 5-year rolling average, which is the average of 5 individual, consecutive points of data. The 5-year rolling average provides a better understanding of the overall data over time without eliminating years with significant increases or decreases; and provides a mechanism for accounting for regression to the mean. If a particularly high or low number of fatalities and/or serious injuries occur in one year, a return to a level consistent with the average in the previous year may occur.

The number targets are calculated by adding the number for the measure for each of the most recent 5 consecutive years ending in the year for which the targets are established, dividing by 5, and rounding to the tenth decimal place. The rate targets are calculated similarly yet rounded to the thousandth decimal place. This more accurately reveals the change from one 5-year average to another that might otherwise be obscured if the number was truncated.

Example: Number of Fatalities
Year 2011 2012 2013 2014 2015
Number of Fatalities 471 468 493 468 462*
*From FARS Annual Report File, if Final FARS is not available

To determine the target for number of fatalities:

Example: Rate of Fatalities per 100 Million VMT
Year 2011 2012 2013 2014 2015
Number of Fatalities 471 468 493 468 462*
VMT per 100 Million 454 490 466 492 495
Rate of Fatalities 1.04 0.96 1.06 0.95 0.93
*From FARS Annual Report File, if Final FARS is not available
