Transportation Performance Management

 

State Highway Safety Report (2021) - Wisconsin

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 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.

More information and resources on Safety Performance Management are available at https://highways.dot.gov/safety/hsip/spm/safety-performance-management-safety-pm-overview.

All State data used to populate the State Highway Safety Reports for 2021 are available for download at https://www.fhwa.dot.gov/tpm/reporting/state/tpm_dashboard_data.zip.

    Number of fatalities target is calculated as a 2% reduction from the most recent 5-year rolling average, which is the performance measure goal identified in the SHSP.

    FARS data was not available at the time of HSP target submittal. Since several HSP targets and HSIP targets must match exactly, all the HSIP targets were established at the same time as the HSP targets. State data was used to calculate the 2023 target for number of fatalities. The historical difference between state fatality data and FARS data was also factored in and accounted for.

Additional Comments

2021 Comments:

1. FARS data was not available at the time of HSIP target submittal. State data was used to calculate the 2021 target for number of fatalities. The historical difference between state fatality data and FARS data was also factored in and accounted for. Final data was not available at the time of HSP target submittal. WisDOT will amend the HSP performance target for number of fatalities to match the HSIP target. 2. Final data was not available at the time of HSP target submittal. WisDOT will amend the HSP performance target for number of serious injuries to match the HSIP target. 3. FARS data was not available at the time of HSIP target submittal.

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.
