Transportation Performance Management

State Highway Safety Report (2021) - Missouri

The following provides a summary of the Highway Safety Improvement Program's (HSIP) safety performance measures and State safety performance targets. As per the Safety PM Final Rule, States are required to set annual safety performance targets in the HSIP annual report for the number of fatalities, rate of fatalities per 100 million vehicle miles traveled (VMT), number of serious injuries, rate of serious injures per 100 million VMT, and number of non-motorized fatalities and serious injuries. The safety performance targets are based on 5-year rolling averages. States have the flexibility to use the methodology they deem most appropriate when establishing safety performance targets. FHWA encourages States to review data sets and trends and consider factors that may affect targets. The safety performance targets should be data-driven, realistic, and attainable and should align with the performance management framework and legislative intent.

A State Department of Transportation (DOT) has met or made significant progress towards meeting its safety performance targets when at least four of the five safety performance targets established under 23 CFR 490.209(a) have been met or the actual outcome is better than the baseline performance. The baseline performance is the 5-year average ending with the year prior to the establishment of the target.

The Basis for Target and Additional Comments are provided by the State in their HSIP Annual Report and have not been edited by FHWA. Any questions about individual State reports should be directed to the respective State DOT. For additional information about each State's HSIP, the complete reports are available at https://highways.dot.gov/safety/hsip/reporting.

  Targets are based on an annual reduction needed to reach Zero fatalities by 2030. This reduction assumes larger decreases in future years as new safety technologies are implemented, such as autonomous vehicles. This target is in line with the SHSP to reduce the number of fatalities on Missouri's roadways.

  The fatality rate was calculated by taking a 5-year rolling average of historical and forecasted annual fatality rates. Historical fatality rates were derived from observed fatality totals and estimated Annual Vehicle Miles Traveled (VMT). Forecasted rates were determined by using the number of fatalities performance target and dividing by the estimated Annual VMT. It was assumed that Annual VMT would grow at a rate of 1% per year. This target is in line with the SHSP to reduce the number of fatalities on Missouri's roadways.

Historical fatality rates were derived from observed fatality totals and estimated Annual Vehicle Miles Traveled (VMT). Forecasted rates were determined by using the number of fatalities performance target and dividing by the estimated Annual VMT. The VMT dropped significantly in 2020, by nearly 10%. It is anticipated at 2021 volumes will rebound by 7% followed by an annual growth rate of 1% per year. This target is in line with the SHSP to reduce the number of fatalities on Missouri's roadways.

In 2021 the VMT rebounded more than anticipated such that it is just slightly higher than 2019. It is anticipated that the typically estimated 1% growth per year will be sufficient moving forward. This target is in line with the SHSP to reduce the number of fatalities on Missouri's roadways.

  The non-motorized fatalities and serious injuries performance target was based on the performance targets for number of fatalities (Zero by 2030) and number of serious injuries (Zero by 2040). An exception is made for instances where the baseline 5-year rolling average (2015-2019) is less than the calculated target. In this instance, the baseline is less than the calculated performance target, and so the baseline was used as the target. This target is in line with the SHSP to reduce the number of fatalities and serious injuries on Missouri's roadways.

Safety Performance Target Assessment

PLEASE NOTE: Each State’s safety performance target assessment is based on its own State-specific target methodology and program philosophy. Therefore, conclusions should not be drawn based only on the information in the Safety Performance Target Assessment Summary table. For example, the State may have set aggressive targets, and not met those targets, while another State may have set more easily attainable targets, and met those targets. FHWA understands that each State’s safety program is unique and therefore does not prescribe a methodology for States to set targets. States have the flexibility to use the methodology they deem most appropriate when setting their safety performance targets.
