Executive Summary

WSDOT is continuing to see growth in volumes and economic activity throughout the state during CY 2019 and 

FY 2020. This trend is considered to be a significant factor in the overall increase in fatal and serious crashes 

statewide. The state set aspirational targets for 2019 after significant discussion with its partner agencies and 

MPOs. WSDOT failed to meet targets. An implementation plan has been developed for FY 2021. WSDOT 

promotes highway safety performance as a top priority for the Department and is communicating this need to 

the public and elected officials. WSDOT continues to transition its HSIP program to be much more systemic 

and this is outlined in WSDOT HSIP Implementation Plan. WSDOT continued to provide local agencies with 

approximately 70% HSIP funds going to locals and 30% to WSDOT. WSDOT uses state funds to supplement 

its safety program. Further, WSDOT is now providing all Railway Highway Crossing Program funds to the 

locals. WSDOT requires counties and cities to have Local Roads Safety Plans to compete for HSIP funding. 

Overall, WSDOT five year trends continue to increase after lows in 2014-15 with moderate increases in 

combined bike/ped fatal and suspected serious injuries. 

WSDOT believes that its working partnerships and commitment to highway safety will drive down crashes, as 

will its evolving the safety program to be more proactive . Emphasis areas will continue to be lane departure, 

intersections, vulnerable road users, data analysis and evaluation. 

WSDOT has chosen to continue setting aspirational targets for the upcoming targets in FY 2021. WSDOT 

believes that setting increasing targets for fatal and suspected serious crashes does not communicate 

WSDOT's desire to reduce the crashes and would not be in keeping with its SHSP Target Zero.

Introduction

The Highway Safety Improvement Program (HSIP) is a core Federal-aid program with the purpose of achieving 

a significant reduction in fatalities and serious injuries on all public roads. As per 23 U.S.C. 148(h) and 23 CFR 

924.15, States are required to report annually on the progress being made to advance HSIP implementation 

and evaluation efforts. The format of this report is consistent with the HSIP Reporting Guidance dated 

December 29, 2016 and consists of five sections: program structure, progress in implementing highway safety 

improvement projects, progress in achieving safety outcomes and performance targets, effectiveness of the 

improvements and compliance assessment. 

Program Structure

Program Administration 

Describe the general structure of the HSIP in the State. 

The WSDOT strategic highway safety plan "Target Zero" is the basis for establishing the programmatic 

structure of WSDOT's approach to programming safety funds, for both WSDOT highways and local roads. 

WSDOT requires local road safety plans for local agencies to be eligible to receive HSIP funding at both the 

county and city level. Currently WSDOT provides 70% of HSIP funds to local roads, and supplements the state 

program with additional state funding. Target Zero emphasis areas and strategies are reviewed and WSDOT 

determines through a review of the leading contributing factors, crash types and behaviors. The plan also 

contain strategies (countermeasures) that can be used as appropriate by State or local agencies, based on 

their specific needs. Washington uses a centralized approach for determining HSIP locations within the state 

using network screening to identify a ranked set of location for further analysis and evaluation. These 

preliminary lists are provided to WSDOT regions to determine the appropriate approaches to address the 

contributing factors to address crashes at the respective locations. The program structure has both crash 

reduction and prevention (systemic) approaches to reducing crash potential. The reduction category focuses 

on spot locations, intersections and segments using expected crashes. The prevention category focus on 

specific contributing factors and crash types to develop a ranked list of potential projects. The projects are 

based on benefit/cost analysis for prioritization of the program of projects. Systemic approaches may use 

network benefit cost or local benefit cost for the purposes of prioritization. WSDOT completed a ten year 

implementation plan that contains additional information on WSDOT Safety Program. 

Where is HSIP staff located within the State DOT? 

 Other-Transportation Safety and Systems Analysis; Local Programs

WSDOT does not have dedicated HSIP staff. Those who complete the reporting are in Transportation Safety 

and Systems Analysis and Local Programs. 

How are HSIP funds allocated in a State? 

 Central Office via Statewide Competitive Application Process 

 SHSP Emphasis Area Data 

 Other-Funds are allocated centrally 

WSDOT and Local HSIP funds are allocated funds based on the total fatal and serious crashes occurring on 

the state versus locally owned roads. The state component is further allocated based on the proportions of 

crashes outlined in the priorities of the SHSP. 
2020 Washington Highway Safety Improvement Program

Page 6 of 72

Describe how local and tribal roads are addressed as part of HSIP. 

Washington uses a data-driven process to determine HSIP funding levels for state vs local roads. The current 

SHSP, "Washington Strategic Highway Safety Plan: Target Zero," (www.targetzero.com) has specified priority 

levels for types/causes/categories of fatal & serious injury crashes based on crash type, driver behaviors, or 

user type. The priority 1 infrastructure related emphasis areas are Lane Departure crashes and Intersection 

crashes. 

To determine the HSIP funding allocation between state and local roadways, WSDOT evaluates the number of 

fatal & serious injury crashes in these priority 1 emphasis areas (lane departure and intersection-related) 

statewide for a consecutive 5-year period. WSDOT calculates the ratio of crashes on local agency 

responsibility roads to those on state highways then allocates HSIP funding between state and local roadways 

based on that percentage. Currently, local agencies receive 70% of HSIP funds and the state receives 30%. 

The 70% of funding that goes to local agency safety is divided into a County Safety Program and a City Safety 

Program. Both programs now require that local agencies submit a Local Road Safety Plan to be eligible to 

apply for HSIP funding. The County Safety Program is focused on fatal and serious injury crash potential with a 

fully systemic approach to prioritizing safety projects. The City Safety Program is both prevention (systemic) 

and reduction (spot locations), with spot safety projects being prioritized by competitive benefit/cost ratio 

statewide. Systemic projects for both counties and cities are prioritized by cost effectiveness of the proposed 

projects, factoring in the crash data & LRSP prioritized projects for each agency, the cost of the proposed 

countermeasures, the number of locations being addressed, and the effectiveness of the countermeasures 

proposed. 

Tribal roads are also eligible for funding, but must be included as part of a county or city list of proposed 

projects (tribes, counties, and cities are all encouraged to include such projects on prioritized lists). Based on 

fatal and serious injury crash data, a standalone tribal safety call for projects would not receive enough funding 

to be viable as a separate statewide call for projects.

Describe coordination with internal partners. 

WSDOT is multimodal and disciplinary. The Highway Safety Issue Group includes representatives from the 

Regions and HQ Divisions and participants may come from planning, programming, design, operations, local 

programs or transportation safety. A safety panel also exists with individuals from multiple discipline areas who 

review projects and countermeasures for inclusion in the safety program. The Highway Safety Executive 

Committee includes Traffic Operations, Design, Capital Programming and Transportation Safety and Systems 

Analysis.

 Law Enforcement Agency 

 Local Government Agency 

 Local Technical Assistance Program 

 Regional Planning Organizations (e.g. MPOs, RPOs, COGs) 

 Tribal Agency 

 Other-WSDOT has organized a Safety Target Setting Organization to establish targets. A safety data

Describe coordination with external partners. 

WSDOT interacts and coordinates with multiple external partners as part of the development of Target Zero 

and in setting targets. WSDOT routinely meets with MPOs and State Highway Safety Office (SHSO) and its 

federal divisions in carrying out its safety program activities. In Target Setting WSDOT will meet with the 

WTSC as necessary to determine the appropriate method for setting targets in the state. The WSDOT will also 

coordinate at this time with MPO Technical, Coordinating or Executive Committees as necessary for getting 

agreement on Targets. For development of the SHSP, WSDOT and the WTSC form multiple working groups to 

assign chapter development, data analysis and oversight of the document. WSDOT and WTSC work closely to 

get partner input and buy-in depending on the specifics of each section of the SHSP. The WTSC is made up of 

Department Heads and works to form and provide Traffic Safety Policy recommendations and direction for 

consideration by the Governor. Often, WSDOT together with different agencies and the WTSC will make 

legislative presentations and submit proposed legislation or funding requests. WSDOT also works very closely 

with city and county agencies to assist with analysis and evaluation of safety plans and projects. 

Describe other aspects of HSIP Administration on which the State would like to 

elaborate. 

WSDOT continues to tie the SHSP emphasis areas, priorities and strategies to the WSDOT safety program 

development. WSDOT will submit its final implementation plan and how the program is administered with an 

outline for each of the safety-sub categories, the methods used and how B/C is used within each sub-category. 

The department is tracking fatal and serious crashes through various means, and has developed a dashboard 

to track COVID-19 issues. 

Program Methodology

Does the State HSIP consider connected vehicles and ITS technologies? 

Yes 

Describe how the State HSIP considers connected vehicles and ITS technologies. 

ITS technology is, and in the future connected vehicles will be, considered as an appropriate countermeasure 

for safety. The countermeasure would need to be shown to have a positive crash reduction potential for fatal 

and serious crashes. An office exists within WSDOT related to connected vehicles and the State Safety 

Engineer interacts with that office. Washington has a committee dealing with CAT related to safety. 

Does the State use the Highway Safety Manual to support HSIP efforts? 

Yes 
2020 Washington Highway Safety Improvement Program

Page 24 of 72

Please describe how the State uses the HSM to support HSIP efforts.

WSDOT uses the HSM throughout its HSIP efforts. The state uses SafetyAnalyst for screening of state 

projects. WSDOT has developed and updated its guide on safety analysis in planning and design and when 

and how to use the HSM for those activities. WSDOT has executive orders that direct policy around the use of 

the HSM. Local HSIP projects priorities are typically derived from the SHSP emphasis areas, and do not use 

the HSM predictive and network screening methods because of data limitations. For Local Agencies we follow 

guidance form the HSM for applying CMFs for our spot location (benefit/cost) projects.

Describe other aspects of the HSIP methodology on which the State would like to 

elaborate.

WSDOT continues to focus on data driven safety analysis throughout its program efforts. WSDOT is using 

performance based practical design and a sustainable safety approach. WSDOT has focused on data driven 

approaches through identifying the 5th E of safety as Evaluation, analysis and diagnosis. It is thought that this 

approach allows for the targeting of specific crash types and contributing factors, and also maximizes the 

return on safety benefit for selected countermeasures. WSDOT outlined the systemic sub-categories that focus 

on road crashes related to road users, intersection, and lane departure crash types. The safety program 

continues to evolve on an ongoing basis.

Discuss impediments to obligating HSIP funds and plans to overcome this challenge in 

the future.

WSDOT provides much of its HSIP appropriation to its local partners. Delivery of federally-funded projects with 

all of the attendant paperwork/regulations can make delivery of these projects by local agencies a challenge, 

especially considering the low-cost nature of many safety improvements. Also revenue reductions related to a 

voter led initiative in Washington has reduced available funds to both the state and locals.

Describe any other aspects of the State’s progress in implementing HSIP projects on 

which the State would like to elaborate. 

WSDOT believes that having the ability to use HSIP funds for non-infrastructure improvements is important to 

reestablish. It would also be helpful to continue to emphasize that expenditure for safety software and data is 

appropriate. Given the changes under MAP-21 and FAST additional wording would be beneficial in 23 USC 

409 and 23 USC 148 that highlights that safety data shared with Safety Partners (MPOs, Health, State Police, 

SHSO) is protected for the agency sharing and receiving the data when used for HSIP purposes (e.g., SHSP, 

Target Setting, Safety Planning, Public Awareness). MPOs in our opinion are reluctant to use this data 

because of potential liability concerns.

Describe efforts to coordinate with other stakeholders (e.g. MPOs, SHSO) to establish 

safety performance targets. 

WSDOT interacts and coordinates with multiple external partners as part of development of Target Zero and in 

setting targets. WSDOT routinely meets with MPOs and the State Highway Safety Office (SHSO) and its 

federal divisions in carrying out its safety program activities. In Target Setting WSDOT will meet with the 

WTSC as necessary to determine the appropriate method for setting targets in the state. This is typically done 

by first meeting with Federal Agencies to discuss concerns related to previous year submissions, and then 

working collaboratively with the WTSC to make changes, if necessary. Prior to finalization, WSDOT will also 

coordinate at this time with MPO Technical, Coordinating or Executive Committees as appropriate to get 

agreement on Target Setting Methods. Because MPOs are fully integrated into WSDOT strategic highway 

safety plan efforts getting agreement is typically done first by indicating meeting early in the year to discuss the 

probable approach then with follow up discussions to finalize. MPOs commonly agree to support reaching 

targets through inclusion of appropriate safety projects, not by setting individual targets. Coordination with both 

the SHSO and MPOs occurs on an ongoing basis.

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2019 Safety Performance Targets (based 

on data available at the time of reporting). For each target, include a discussion of any 

reasons for differences in the actual outcomes and targets.

WSDOT sets aspirational targets with the believe that it is important to reduce fatal and serious crashes to 

extent possible. The ability to communicate is enhanced when the targets are consistent with the SHSP.

Applicability of Special Rules

Does the HRRR special rule apply to the State for this reporting period? 

Yes

WSDOT was a HRRR state for this reporting period, but will not be in the next federal fiscal year.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

 Benefit/Cost Ratio 

 Change in fatalities and serious injuries 

Based on the measures of effectiveness selected previously, describe the results of 

the State's program level evaluations. 

WSDOT is experiencing significant growth across the state. This increase in exposure is believed to related to 

increase in crash potential. Washington is seeing fatal and serious crashes remaining relatively stable, with 

some decreases in pedestrian related crash based after a peak in 2017. County and Cities are not seeing the 

significant increases as were seen between 2013 (low) to 2017. Washington continues to measure overall 

progress by jurisdictional type of road (state, county, city). Each of these jurisdiction types is primarily funded 

through separate programs within the HSIP, so this seems like a reasonable way to monitor progress of those 

programs. 

Statewide we compare the 5-year rolling average from 2011-2015 with the 5-year rolling average from 2015-

2019. This overlaps the year 2015 in each data set, which then is really a comparison of the 4 years before the 

projects in 2015 were completed with the 4 years after the projects were completed. By jurisdictional road type, 

those comparisons show: 

State Highways: 2011-2015 = 708.4 fatal/serious crashes vs 2015-2019 = 790.8 fatal/serious crashes, or a 

12% increase. 

County Roads: 2011-2015 = 539.8 fatal/serious crashes vs 2015-2019 = 542.0 fatal/serious crashes, or a 0% 

increase.

City Streets: 2011-2015 = 914.6 fatal/serious crashes vs 2015-2019 = 1032.8 fatal/serious crashes, or a 13% 

increase. 

Note that state highways that serve as city streets (in cities of 27,500+ population) are included in the city 

streets data here. 

These measures show the least change for county roads, which have been developing Local Road Safety 

Plans (since 2014) and implementing a systemic safety program (since 2009). 

However, these results analyzing 2015 do not account for larger statewide factors as noted above, including 

changes in population, VMT, gas prices, the economy, or other effects (such as state legalization of 

marijuana), which can also have significant effects on the numbers reported here during the same time frame. 

WSDOT reviews the benefit and cost of its safety program subcategories to determine if investments are 

returning sufficient value in terms of reduction in fatal and serious crashes. Over time subcategory cost, 

benefits, or requirements may change and the relative value of a subcategory may go up or down. In addition, 

it is typical to prioritize projects with higher B/Cs. 

What other indicators of success does the State use to demonstrate effectiveness and 

success of the Highway Safety Improvement Program? 

 Increased awareness of safety and data-driven process 

 Increased focus on local road safety 
2020 Washington Highway Safety Improvement Program

Page 63 of 72

 More systemic programs 

 Organizational change 

 Policy change 

Describe significant program changes that have occurred since the last reporting 

period.

WSDOT is transitioning its program from a 70% reduction to 30% prevention to a 70% prevention (systemic) to 

30% reduction funding strategy. In addition a specific subcategory has been developed for active 

transportation. The Local Programs continues to expand the development and use of local road safety plans.
