Transportation Performance Management

 

State Highway Safety Report (2020) - Vermont

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/.

More information and resources on Safety Performance Management are available at https://safety.fhwa.dot.gov/hsip/spm/.

All State data used to populate the State Highway Safety Reports for 2020 are available for download at https://www.fhwa.dot.gov/tpm/reporting/state/tpm_dashboard_data.zip.

    5-Year Average 60.0 60.6 61.6
    Target (5-Year Average) 58.0 58.0 58.0
  • Basis for Number of Fatalities Target

    The trend line used for this performance measure utilizes a linear model to establish the 2020 target. This trend suggests a decrease in traffic fatalities by 3% from the five-year average of 62.0 in 2014 - 2018 to a five-year average of 58 by the end of calendar year 2020. The 2017-2021 Strategic Highway Safety Plan measures success in term of overall crash reduction in serious and fatal crashes with a goal of 10% reduction by 2021. The percentage reduction in fatalities expected by this target supports the goal of the SHSP by providing a 3% reduction in the five-year average over two years.
    The trend line value for the 5-year average number of fatalities predicted for 2021 using a linear regression model is 60.4. The 2019 actual 5-year average number of fatalities was 60.8 and the 2019 target was 56 while the 2020 target was 58. A 2021 target of 58 provides a decrease in traffic fatalities by 4.6% from the five-year average of 60.8 in 2015 – 2019 to a five-year average of 58 by the end of calendar year 2021. The 2017-2021 Strategic Highway Safety Plan measures success in term of overall crash reduction in serious and fatal crashes with a goal of 10% reduction by 2021. This represents approximately a 2.5% reduction per year. The percentage reduction in fatalities expected by this target supports the goal of the SHSP by providing a 4.6% reduction in the five-year average over two years.
    While the coordinating committee realized that the actual value for this target had plateaued over the years, the committee favored the idea of the 2022 safety target for fatal crashes not to be higher than the one from the previous year (the 2021 target was 58). With this in mind, the committee decided to keep the 2022 target the same as for 2021. A 2022 target of 58 provides a decrease of 5.5% from the five-year average of 61.4 in 2016–2020 and supports the goal of the SHSP by providing a reduction in the five-year average above 4.0% over two years.

  • Basis for Fatality Rate Target

    The trend line used for this performance utilizes a logarithmic model to establish the 2020 target. This trend suggests a decrease in the fatality rate per 100 million VMT by 1.2% from the five-year average of 0.83 in 2014 - 2018 to a five-year average of 0.82 by the end of calendar year 2020. This proposed target is downwards and supports the overall reduction in fatal and serious crashes presented in the 2017-2021 Strategic Highway Safety Plan.
    The trend line value for the 5-year average fatality rate predicted for 2021 using a linear regression model is 0.815. The 2019 target was 0.800 and the actual 2019 5-year average fatality rate was 0.831.The 2020 target was 0.820. The proposed target suggests a decrease in the fatality rate per 100 million VMT by 1.3% from the five-year average of 0.831 in 2015 - 2019 to a five-year average of 0.820 by the end of calendar year 2021. This proposed target is downwards and supports the overall reduction in fatal and serious crashes presented in the 2017-2021 Strategic Highway Safety Plan.
    This measure is highly dependent on the number of vehicle miles traveled (VMT). Vermont's 2021 target for the fatality rate five-year average was 0.82. This number is slightly higher than what is estimated (0.80) for a 2% SHSP yearly reduction with 2020 normal conditions and is also lower than what could be obtained for a 2% SHSP yearly reduction under existing conditions with the lower VMT due to pandemic restrictions (0.84). Vermont is still seeing a 15-18% reduction in traffic volumes as compared to 2019, and VTrans does not expect the VMT to get back to the usual 7.5 billion range in the near future. However, the coordinating committee decided to retain the same rate as for the 2021 target (0.82). The proposed target suggests a decrease in the fatality rate per 100 million VMT of 5.8% from the five-year average of 0.871 in 2016-2020 to a five-year average of 0.820 by the end of calendar year 2022 and supports the goal of the SHSP by providing a reduction in the five-year average above 4.0% over two years.

  • Basis for Number of Serious Injuries Target

    The trend line used for this performance measure utilizes a 2nd degree polynomial model to establish the 2020 target. This trend suggests a decrease in serious injuries by 2.9% from the five-year average of 283.2 in 2014 - 2018 to a five-year average of 275 by the end of calendar year 2020. The 2017-2021 Strategic Highway Safety Plan measures success in term of overall crash reduction in serious and fatal crashes with a goal of 10% reduction by 2021. The proposed target reduces the number of serious injuries by 2.9% in the five-year average over two years and supports the goal of the SHSP.
    The trend line value for the 5-year average number of serious injuries predicted for 2021 using a 2nd degree polynomial model is 270.6. The 2019 target was 265 and the actual 2019 5-year average number of serious injuries was 277.8. The 2020 target was 275. The propose 2021 target suggests a decrease in serious injuries by 1.0% from the five-year average of 277.8 in 2015 - 2019 to a five-year average of 275 by the end of calendar year 2021. The proposed target is a reduction in the 5-year serious injury rate, which supports the overall reduction in fatal and serious crashes presented in the 2017-2021 Strategic Highway Safety Plan.
    Serious injuries have been trending down over the last several years. The Excel trendline proposes that the five-year average will be around 270 serious injuries in 2022. A value below this trendline was selected in order to achieve progress towards the SHSP goal. The proposed target suggests a decrease of 2.1% from the five-year average of 265.6 in 2016-2020 to a five-year average of 260 by the end of calendar year 2022. This proposed target is downwards and supports the overall reduction intent of the SHSP.

  • Basis for Serious Injury Rate Target

    The trend line used for this performance measure utilizes a 2nd degree polynomial model to establish the 2020 target. This trend suggests a decrease in the injury rate per 100 million VMT by 5.1% from the five-year average of 3.9 in 2014 - 2018 to a five-year average of 3.7 by the end of calendar year 2020. The proposed target is a reduction in the 5-year serious injury rate, which support the overall reduction in fatal and serious crashes presented in the 2017-2021 Strategic Highway Safety Plan.
    The trend line value for the 5-year average serious injury rate predicted for 2021 using a linear regression model is 3.422. The 2019 target was 3.900 and the actual 2019 5-year average fatality rate was 3.796. The 2020 target was 3.750. The proposed target suggests a decrease in the injury rate per 100 million VMT by 3.8% from the five-year average of 3.796 in 2015 - 2019 to a five-year average of 3.65 by the end of calendar year 2020. The proposed target is a reduction in the 5-year serious injury rate, which supports the overall reduction in fatal and serious crashes presented in the 2017-2021 Strategic Highway Safety Plan. The percentage reduction in the serious injury rate expected by this target supports the goal of the SHSP by providing a 3.8% reduction in the five-year average over two years.
    A value of 3.65 was established for the 2021 target for the suspected serious injury rate five-year average. The actual 2020 value was 3.75. A 2020 value would have been around 3.60 to 3.68 with more realistic VMTs and maybe a slightly higher number of injuries. More normal conditions for 2020 suggest that an even lower value of near 3.5 would be needed to keep up with the SHSP. However, the coordinating committee felt that keeping this target near the 2021 value (3.65) would be preferable. This is another target that is dependent on the VMT and as mentioned previously, VTrans does not expect VMT to go back to pre-pandemic levels in the near future. The proposed target suggests a decrease of 1.4% from the five-year average of 3.752 in 2016-2020 to a five-year average of 3.7 by the end of calendar year 2022. This proposed target is downwards and supports the overall reduction intent of the SHSP.

    The trend line used for this performance measure utilizes a 3rd degree polynomial model to establish the 2020 target. This trend suggests a decrease in the number of bicyclist/pedestrian fatalities and serious injuries by 5.8% from the five-year average of 38.2 in 2014 - 2018 to a five-year average of 36 by the end of calendar year 2020. The 2017-2021 Strategic Highway Safety Plan considers pedestrians and bicyclists as two separate emphasis areas with their own sets of strategies. The reduction goal for each of these two emphasis areas in the 2017-2021 Strategic Highway Safety Plan is a 10% reduction if fatal and serious injury crashes. The proposed target is downward and contribute to the overall goal of the Strategic Highway Safety Plan.
    The trend line value for the 5-year average number of bicyclist/pedestrian fatalities and serious injuries predicted for 2021 using a 3rd degree polynomial model is 33.817. The 2019 target was 35 and the actual 2019 5-year average was 39.8. The 2020 target was 36. The proposed target suggests a decrease in the number of bicyclist/pedestrian fatalities and serious injuries by 9.5% from the five-year average of 39.8 in 2015 - 2019 to a five-year average of 36 by the end of calendar year 2021. The 2017-2021 Strategic Highway Safety Plan considers pedestrians and bicyclists as two separate emphasis areas with their own sets of strategies. The reduction goal for each of these two emphasis areas in the 2017-2021 Strategic Highway Safety Plan is a 10% reduction if fatal and serious injury crashes. The percentage reduction expected by this target supports the goal of the SHSP by providing a 9.5% reduction in the five-year average over two years.
    The 2021 target for the number of non-motorized fatalities and non-motorized suspected serious injuries five-year average was 36. This value is about what is expected to happen from the Excel trend line for 2022. This value is slightly higher than what VTrans calculated as a target that supports the SHSP (34.8). To align with the SHSP, the coordinating committee decided to use a 5-year average of 35. The proposed target suggests a decrease in the five-year average of 3.3% from the five-year average of 36.2 in 2016-2020 to a five-year average of 35 by the end of calendar year 2022. This proposed target is downwards and supports the overall reduction goal of the SHSP.

Additional Comments

2020 Comments:

The target for the number of serious injuries in this HSIP report is different from the one submitted for the HSP. The reason is that an error was detected and the wrong number was provided in the HSP. A revised target for the HSP will be provided to NHSTA by the State Highway Safety Office.

2021 Comments:

With the exception of the target for serious injuries, all the other targets are the same as the 2020 targets. All targets, with the exception of the one for the number of fatalities, have been set between the 2021 trend value and the 2019 actual 5-year average. The target for the number of fatalities was set slightly lower than the trend line to match the 2020 target which VTrans felt was a better target to aim for. The targets for the number of fatalities and for the number of serious injuries in this HSIP report are different from the ones submitted for the HSP. The wrong numbers were provided in the HSP. VTrans is working with NHTSA to correct the numbers in the HSP.

2022 Comments:

VTrans has attempted to align the 2020 safety performance targets with the overall five-year goal of the SHSP rather than by trend lines. VTrans believes that this approach is more useful for making decisions towards investments. VTrans endeavored to determine what the safety targets should be in order to make progress towards a 10% SHSP overall reduction in the of fatal and serious injury crashes five-year average over five years (assuming that the 10% goal from the previous SHSP will be continued in the next SHSP update). The year 2022 will be the first year of VTrans’ updated SHSP. To keep it simple, VTrans assumed a 2% reduction per year. The 10% reduction should be from the 2021 averages, but because these are unknown for now, VTrans assumed a 4% reduction from the 2020 actual values. VTrans used Excel trend lines and generated predictions with ARIMA models for the year 2022 for all five five-year average safety targets as reference points.

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.
