Transportation Performance Management

 

State Highway Safety Report (2019) - Arkansas

Select HSIP Report Year:

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. 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://safety.fhwa.dot.gov/hsip/reports/.

  • Number of Fatalities

  • Number of Fatalities 2013 2014 2015 2016 2017 2018 2019 2020 2021

    Target (5-Year Average) 543.0 541.2 536.3
  • Basis for Number of Fatalities Target

    Through extensive coordination with the Arkansas Highway Safety Office, FHWA, NHTSA, all MPOs, and other stakeholders, a methodology to determine the targets was developed. This methodology is similar to the previous year’s methodology.
    The first step in the methodology was to calculate the moving average for the last five years. A moving average “smooths” the variation from year to year, which accounts for variation of the data. Next, an average of each value was calculated.The preliminary fatality number in FARS shows 545 for 2016, which is used for the 2012-2016 moving average calculation. The FARS data typically get adjusted prior to being finalized. As a result, the National Safety Council (NSC) data for 2016 is reviewed to determine the level of adjustment to account for potential corrections made to the FARS data later in the year. The NSC fatality number shows 560 for 2016.

    Once the average of the moving averages was calculated for each performance measure, external factors were considered to determine if and how they would impact safety performance. These external factors include the following:
    • The recent state legalization of medical marijuana.
    • The possible increase in speed limit on freeways/expressways.

    This target supports the SHSP goals of reducing Fatalities and Serious Injuries Statewide.
    See attached PDF for description.
    In 2017 when SHSP was completed, eCrash was not as widely implemented as it is today so we are capturing more crash records leading to constantly adjusted targets. See attached PDF for additional details.

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.
