Executive Summary

The Iowa DOT Traffic and Safety Bureau has continued to develop and implement a data-informed safety 

program. The Bureau is back to full staff following the hiring of three new staff members. Significant milestones 

since the last report have included: 

-updates and expansion of the SPF based Potential for Crash Reduction (PCR) tool for the 2016-2020 period 

to include statewide intersections as well as addition of the Primary system for segments, 

-completion of a new Benefit/Cost tool, 

-implementation of a completed ICE policy, 

-delivery from consultant of Iowa calibrated Crash Prediction Tool spreadsheets to incorporate HSM Part C 

predictive methods for rural two lane, multilane, and urban and suburban arterials, 

-development of a Safety Analysis Guide for internal and external users. 

Statewide crash data continues to be improved with more automation for the weekly data download process, 

providing current crash data for the GIS-based Iowa Crash Analysis Tool.

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 state's HSIP funds are assigned to three different categories: District Initiatives, Statewide Initiatives, and 

Interstate High Contrast Pavement Markings (for 5-years). District Initiative projects are identified by the 

districts, based on their local knowledge or results of a safety study combined with data-driven methods such 

as their District Road Safety Plan or the SPF-based Potential for Crash Reduction (PCR) tool recently 

developed for Primary segments and statewide intersections. Statewide Initiative projects are identified by 

Traffic and Safety Bureau staff based on research/study results, and can involve a mixture of reactive/sitespecific and risk-based systemic improvements, especially when they can be applied at multiple locations 

across various districts. All projects are selected for funding by central office staff. District projects are 

approved for funding based on whether they were identified by their respective District Road Safety Plan, if a 

benefit-cost ratio exceeds one, or based on the Potential for Crash Reduction level (High or Medium). District 

projects are typically designed in-house, but the majority of statewide projects are designed by an outside 

consultant. The 5-year Interstate High Contrast Pavement Markings plan is being incorporated with Traffic and 

Safety Bureau and Maintenance Bureau staff, and designed by relevant district staff. All projects are tracked by 

central office staff, including crashes, costs, and construction dates. Crashes for 3 to 5 years pre-construction 

are compared 3 to 5 years of post-construction crashes, and a benefit-cost analysis is conducted for all 

projects. 

Where is HSIP staff located within the State DOT? 

 Operations

How are HSIP funds allocated in a State? 

• Formula via Districts/Regions 

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

Iowa utilizes state funds to address safety on local and tribal roads. HSIP-Secondary addresses safety issues 

on the Secondary (county-owned) roadway system, and is focused on funding projects incorporating systemic, 

low-cost safety improvements. Typical countermeasures include rumble strips, grooved-in pavement markings, 

paved shoulders, improved signage, and guardrail updates. This program is going to be renamed HSIP-Local, 

receive a funding increase from $2 million to $5 million, and expand to also include City/MPO applications. 

Some additional countermeasures may also be added, such as reflective sign strips and curve warning signs. 

The program is also expected to be used for local match for SS4A Safety Action Plan development. 
2022 Iowa Highway Safety Improvement Program

Page 6 of 34

Additional safety improvements on other local roads, including county, city, institutional, and tribal roads, are 

addressed via the state's Transportation Safety Improvement Program (TSIP). TSIP is a competitive, 

application-based program that awards approximately $7 million in state funds annually for safety projects on 

and off the state system. Funding is provided in three categories: studies and outreach, the purchase of traffic 

control devices, and the construction of larger infrastructure projects. 

Identify which internal partners (e.g., State departments of transportation (DOTs) 

Bureaus, Divisions) are involved with HSIP planning. 

• Districts/Regions 

• Maintenance 

• Traffic Engineering/Safety 

Describe coordination with internal partners. 

Most HSIP projects are designed and administered by staff in the six Iowa DOT Districts. Therefore, the 

Districts are consulted early and often in the HSIP planning process. As described above, approximately 80% 

of the HSIP project funding is designated to "District Initiatives" (between 12-16% per district) which are 

submitted as candidates and selected based on funding availability and alignment with SHSP emphasis areas 

and strategies, most frequently intersections and lane departures. A large majority of funding goes toward 

addressing lane departure crashes through shoulder improvements and associated shoulder and centerline 

rumble strips, most commonly paving existing shoulders. Districts identify projects based on local knowledge 

combined with data-driven methods such as recommendations from the risk-factor based District Road Safety 

Plans and the SPF based Potential for Crash Reduction tool, especially with the recent completion of PCR for 

Primary segments. 

Interstate High Contrast pavement marking projects are coordinated with the DOT Maintenance Bureau, as are 

potential rumble strip shoulder and centerline retrofit projects. DOT Program Management Bureau also reviews 

the HSIP before submittal to FHWA. 

Identify which external partners are involved with HSIP planning. 

• FHWA 

Describe coordination with external partners. 

The State Safety Engineer and HSIP manager meet annually with FHWA Iowa Division personnel to review the 

state's HSIP approval process and update it, if necessary. FHWA Division staff and DOT Traffic and Safety 

Bureau staff also communicate through emails and phone calls throughout the year. 

Program Methodology 

Does the State have an HSIP manual or similar that clearly describes HSIP planning, 

implementation and evaluation processes? 

Yes 

The state HSIP Manual (2019) will will receive minor updates in calendar year 2023. These will address the 

additional tools that have been developed at Iowa DOT such as the Safety Performance Function (SPF) based

Potential for Crash Reduction (PCR) tool that is being further integrated into the project development process 

(discussed in Question 19), as well as the draft Safety Analysis Guide (December 2021) that will be finalized 
2022 Iowa Highway Safety Improvement Program

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

Yes 

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

Iowa is making steady progress for increasing incorporation of the Highway Safety Manual (HSM) in project 

development and design. 

With respect to safety project candidate identification and development, safety performance functions (SPF) 

have been developed by category (and calibrated) forPrimary road segments and for All intersections 

statewide (that have AADT traffic data and at least one paved approach). The next phase will add 

allSecondary road segments, and is nearly complete. This SPF values are then compared with 5-year 

intersection/segment crash data (corrected using empirical bayes methodology) 'corrected' to develop 

Potential for Safety Improvement, referred to for Iowa DOT as "Potential for Crash Reduction" (PCR). This 

PCR tool is incorporated into a GIS webpage and has been updated for 2014-2018 and 2016-2020, with 

continuous 2-year updates anticipated. This is being used by various DOT bureaus as well as local agencies 

and project consultants for data driven network screening and safety project prioritization. 

Once project candidates are identified, intersection and segment crash distribution dashboards are being 

generated to compare individual intersection and segment crash distributions to similar locations within the 

same category, identify crash types that are over-represented, and thus identify potential countermeasures. 
2022 Iowa Highway Safety Improvement Program

Page 9 of 34

Although the state has been using crash modification factors (CMFs) for years, the number of CMFs available 

on the CMF clearinghouse has grown exponentially, and there remain many countermeasures for which a 

good CMF does not exist, or the most appropriate is difficult to select. Therefore, the need for state-specific 

CMFs was identified, and a list of approximately 70 commonly used CMFs was published in August 2019. This 

list will be updated as needed with refined values or new countermeasures, likely on a 2-4 year basis. 

Finally, a consultant has developed a state-specific framework for conducting safety evaluations consistent 

with HSM Part C methods, via a spreadsheet tool. The rural two-lane, rural multilane, and urban/suburban 

arterial versions of the tool have been delivered to the state, and some Districts are current "pilot-testing" this 

tool for Concepts and Alternatives, including for planned Super-2 corridors.

$31,500,000

On July 22, 2022, $17.5 million from FY 2022 and $14 million from FY 2021 (Total $31,500,000) was 

transferred from HSIP to NHP per FMISL11A report.

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

the future.

There is an adequate supply of HSIP project candidates identified by the Districts and the Traffic and Safety 

Bureau. However, impediments to fully obligating programmed HSIP funds include proper estimating and long 

development timelines between HSIP project identification and ultimate project design and bidding. 

Initial cost estimates tend to be high in order to account for project uncertainties and to avoid having to ask for 

more money at a later time. Rapid changes in material availability have affected estimates differently 

depending on when in the year the project was bit. In addition, the high visibility interstate pavement marking 

estimates appear to have been have been overly conservative for this year, but this may not be the case in 

future years with additional material shortages. 

Project development timelines can be affected by multiple external forces including coordination, clearances, 

and unforeseen circumstances. Our goal is to work with project sponsors and project managers to improve the 

accuracy of cost estimates and to minimize time delays in order to obligate HSIP funds to the fullest extent.

Safety Performance Targets 

Safety Performance Targets 

Calendar Year 2023 Targets *

Number of Fatalities:351.4

Describe the basis for established target, including how it supports SHSP goals.
2022 Iowa Highway Safety Improvement Program

Page 23 of 34

A simple trend analysis of historical fatality data was performed. An integrated moving average model was run 

to estimate how much risk would be associated with each set of predictions. Our working group settled on 

using a 75% confidence level. This means we are at least 75% confident the actual 5-year rolling average will 

be less than the target.

Number of Serious Injuries:1398.2

Describe the basis for established target, including how it supports SHSP goals.

A simple trend analysis of historical serious injury data was performed. An integrated moving average model 

was run to estimate how much risk would be associated with each set of predictions. Our working group settled 

on using a 75% confidence level. This means we are at least 75% confident the actual 5-year rolling average 

will be less than the target.

Fatality Rate:1.073

Describe the basis for established target, including how it supports SHSP goals.

A simple trend analysis of historical fatality data was performed. An integrated moving average model was run 

to estimate how much risk would be associated with each set of predictions. Our working group settled on 

using a 75% confidence level. This means we are at least 75% confident the actual 5-year rolling average will 

be less than the target. This target supports the SHSP goal of continuing to reduce the fatality rate to 

1.000 per HMVMT.

Serious Injury Rate:4.264

Describe the basis for established target, including how it supports SHSP goals.

A simple trend analysis of historical serious injury data was performed. An integrated moving average model 

was run to estimate how much risk would be associated with each set of predictions. Our working group settled 

on using a 75% confidence level. This means we are at least 75% confident the actual 5-year rolling average 

will be less than the target. This target supports the SHSP goal of continuing to reduce the serious injury 

rate below 4.300 per HMVMT.

Total Number of Non-Motorized Fatalities and Serious Injuries:134.4

Describe the basis for established target, including how it supports SHSP goals.

A simple trend analysis of historical non-motorized fatality and serious injury data was performed. An 

integrated moving average model was run to estimate how much risk would be associated with each set of 

predictions. Our working group settled on using a 75% confidence level. This means we are at least 75% 

confident the actual 5-year rolling average will be less than the target.

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

safety performance targets. 

The DOT's safety target working group established the methodology for setting the performance targets, using 

the same process as last year and the year before. The chosen targets and a description of the methodology 

were shared with representatives from the Governor's Traffic Safety Bureau for discussion. DOT and DPS 

leadership discussed aspirational targets and resolved to continue with statistically driven target setting. 
2022 Iowa Highway Safety Improvement Program

Page 24 of 34

A draft safety memo outlining the chosen targets and methodology was sent to all MPOs in the state with a 

request for comments. No substantive comments regarding the targets or the methodology were received 

during the comment period.

Iowa DOT and DPS have continued to promote institutional changes in service of an aspirational goal less to 

reduce fatalities to less than 300 fatalities per year. 

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2021 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.

PERFORMANCE MEASURES TARGETS ACTUALS

Number of Fatalities 336.8 335.8

Number of Serious Injuries 1370.8 1374.6

Fatality Rate 0.983 1.026

Serious Injury Rate 4.002 4.192

Non-Motorized Fatalities and 

Serious Injuries

131.0 135.0

The state met its target for the 5-year average number of fatalities. The state did not meet its target for the 5-

year average number of serious injuries (0.28% above), the 5-year average fatality rate (4.37% above), the 5-

year average serious injury rate (4.78% above), or the 5-year average number of non-motorized fatalities and 

serious injuries (3.05% above).

Comparing this 2017-2021 5-year Target and Actual data with the 2015-2019 Baseline data for the forthcoming 

Performance Target assessment, Iowa will have met or made significant progress in 3 of 5 performance 

measures - "Meeting the Target" in Number of Fatalities, and "Better than Baseline" in Number of Fatalities, 

Fatality Rate, and Serious Injury Rate, and slightly worse than Baseline in Fatality Rate (1.024 Baseline vs 

1.026 Actual) and Non-Motorized Fatalities and Serious Injuries (133.4 Target vs 135 Actual).

Two variables that are believed to contribute to this variation between the Target and Actual performance 

measures are reductions in vehicle miles traveled (VMT) during 2020-2021 during the Covid-19 pandemic, and 

the simultaneous increase in risky driver behaviors observed nationwide - such as more drivers speeding over 

the posted speed limit and speeding at higher rates of speed, more distracted and impaired driving, lower rates 

of enforcement, etc. These behaviors result in more fatal and serious injury crashes, and the VMT reductions 

result in higher rates. 

Applicability of Special Rules

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio 

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

the State's program level evaluations. 

As a summary since fiscal year 2001, the state's HSIP expenditures have resulted in a benefit-cost ratio of 

approximately 6 to 1. Some of the highest B-C ratios resulted from extremely low-cost improvements such as 

supplemental roadway signs, lighting, or roadside clearing. 

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

success of the Highway Safety Improvement Program? 

• HSIP Obligations 

• Increased awareness of safety and data-driven process 

• Increased focus on local road safety 

• Organizational change 

• Policy change
