Executive Summary

In July 2017, the Illinois Department of Transportation (IDOT) updated its Strategic Highway Safety Plan 

(SHSP) with the ultimate goal of reaching zero fatalities and serious injuries on all Illinois roads by the year 

2034. One of the strategies mentioned in the plan, was the Federal Highway Administration’s (FHWA) Highway 

Safety Improvement Program (HSIP).

HSIP in Illinois is a data-driven program whose purpose is to provide funding for proven countermeasures to 

reduce fatalities and serious injury crashes on Illinois roadways. IDOT’s Bureau of Safety Programs and 

Engineering (BSPE) oversees the program and HSIP Committee while working with other safety partners such 

as the FHWA, IDOT’s Bureau of Operations, IDOT’s Bureau of Local Roads, IDOT districts, and local agencies 

and MPOs. Currently, IDOT districts may apply for HSIP funds year-round, while local agencies and MPOs 

may apply for projects only once a year.

The HSIP Committee approves projects based on several factors such as historical crash data, appropriately 

chosen countermeasures based on the crash history, and the benefit/cost value. In recent years, the HSIP 

Committee has been trying to encourage IDOT districts and local agencies to consider alternative strategies as 

suggested by the FHWA such as innovative intersections or utilizing systemic approaches.

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. 

IDOT has an HSIP policy which identifies the process for data analysis, project application, project review, and 

approval and can be accessed via. IDOT is currently still in the process of updating the HSIP Policy and 

creating an HSIP Evaluation Tool. 

Illinois' HSIP is overseen by IDOT's Bureau of Safety Programs and Engineering (BSPE). IDOT districts are 

allowed to submit applications throughout the year for the HSIP Committee to review at their monthly meetings. 

Local agencies are able to submit once a year when the application period is open. Both state and local are 

reviewed based using a data-driven and proven countermeasure approach. 

Where is HSIP staff located within the State DOT? 

 Other-Bureau of Safety Programs and Engineering

How are HSIP funds allocated in a State? 

20% is allocated for local use, 20% is allocated for statewide safety initiatives, and remaining is divided 

between districts based on fatality rates. 

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

Each year there is a period in which local agencies and MPOs are able to apply for funding for local projects. 

When the window to apply begins, BSPE hosts a webinar for local agencies and MPOs to inform them of the 

HSIP process and provide examples of HSIP applications are likely to be approved or denied. Through 

coordination with IDOT’s Bureau of Local Roads, local applications are received and then reviewed. Local 

HSIP applications are reviewed with the same criteria as state applications. A history of crashes must be 

shown, a countermeasure selected to address the crashes, and the benefit/cost analysis. 

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

Bureaus, Divisions) are involved with HSIP planning. 

• Design

• Districts/Regions 

• Local Aid Programs Office/Division 

• Operations 
2020 Illinois Highway Safety Improvement Program

Page 6 of 43

• Traffic Engineering/Safety 

Describe coordination with internal partners. 

IDOT's HSIP Committee (formerly referred to as the Central Traffic Safety Committee in previous online 

reports) is comprised of several IDOT members from various bureaus within IDOT. Most are from the Bureau 

of Safety Programs and Engineering (BSPE), but there are also members from the Bureau of Operations and 

Bureau of Design and Environment and one IDOT district who have their own unique perspective and area of 

expertise. 

The HSIP Committee also works closely with IDOT districts on HSIP applications. Even if an application is 

denied, the HSIP Committee will provide a reason for the denial and suggestions for the district to reapply 

using a different and more appropriate countermeasure based on the observed crash data. The HSIP 

Committee also encourages an open dialogue with the districts and ensure they're welcome to reach out to the 

HSIP Committee on any possible projects. 

One instance featured a district unsure of support for a roundabout. The HSIP Committee reviewed the data 

and agreed to meet with the district in which the HSIP Committee agreed with the proposed roundabout. An 

application followed shortly after which the HSIP Committee approved. 

Each year when the submittal window for Local HSIP projects is open, the HSIP Committee works closely with 

the Bureau of Local Roads (Local Aid) in coordinating the submittal of Local HSIP applications. The Bureau of 

Local Roads works with the HSIP Committee in reviewing and approving or denying Local HSIP applications. 

Identify which external partners are involved with HSIP planning. 

• FHWA 

• Local Government Agency 

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

• Other-Local Agencies 

Describe coordination with external partners. 

Besides IDOT employees, the HSIP Committee includes FHWA staff. Should a question arise about funding or 

the eligibility of projects, the HSIP Committee will reach out to their external partners at FHWA. 

Similar to how the HSIP Committee encourages IDOT districts to reach out with any questions regarding HSIP, 

the HSIP Committee encourages local agencies and MPOs to reach out and provides feedback and comments 

on Local HSIP applications. The HSIP Committee ensures they have access to the latest BSPE tools such as 

the safety tiers, data trees, emphasis area tables and graphs, crash data, and crash analysis tool, and putting 

them into contact with the IDOT safety contact from their respective IDOT district. 

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

elaborate. 

HSIP in Illinois is administered by the HSIP Committee. The HSIP Committee is overseen by IDOT’s Bureau of 

Safety and Programs (BSPE)’s Safety Design Unit Chief. The HSIP Committee is made of members from 

BSPE, IDOT’s Bureau of Operations and Bureau Design and Environment, and FHWA. All projects are 

approved based on the 90/10 split, with 90% of the project cost being paid for by HSIP funds and the 

remaining 10% paid for by either the district or local agency requesting the HSIP funding. 
2020 Illinois Highway Safety Improvement Program

Page 7 of 43

Once a month, The HSIP Committee reviews new HSIP applications for projects on state roadways. Any of the 

nine IDOT districts can submit an HSIP application through the HSIP SharePoint site. Each application must 

include the five most recent years of available crash data for the location, a detailed cost sheet, a project 

description, and a completed copy of Illinois’ benefit/cost tool spreadsheet which is available via IDOT’s 

website. Ideally, the application will have supporting documentation such as plans, photos of existing 

conditions, and the location. At the monthly meeting the HSIP Committee then decides to approve or deny 

each application. Applications may be reviewed with partial funding, or denied, but encouraged to resubmit 

based on feedback from the HSIP Committee. 

The HSIP Committee also works with members from IDOT’s Bureau of Local Roads in administering HSIP 

projects on local roads. Local agencies and MPOs can apply once a year for local HSIP projects. The 

requirements for local HSIP applications are the same as state applications. 

After applications are approved, the district or local agency are then notified so they can continue with the next 

steps of programming and constructing their project. For the HSIP Committee to perform an evaluation on the 

effectiveness of the project, they require five years of after data.

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.

The HSM was used as a basis for developing Illinois calibrated safety performance functions (SPFs). These 

SPFs have been used in the development of Illinois’ safety tiers and other tools which assist in HSIP 

identification and approval process. Each HSIP application requires a benefit/cost analysis using proven, highquality countermeasures from the CMF Clearinghouse and HSM. HSIP projects completed from 2007 – 2015 

were evaluated using methods found in the HSM.

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

the future.

They are several obstacles to the obligation of HSIP funds such as the obtainment of right of way, compliance 

with the federal National Environmental Policy Act, and Buy America. Purchasing right of way can sometimes 

be a tedious and drawn out process depending on the roadway owner and purchase amount. The National 

Environmental Policy Act can cause issues at site locations by prohibiting or limiting what construction can take 

place. Buy America has caused issues with several recent projects as the requested equipment to be 

purchased—moveable barrier wall to be used in construction zones, and a pavement striper to be used for 

striping unmarked rural roads—as every single piece of the equipment could not be guaranteed to be made in 

America.

To combat these issues, the HSIP Committee takes them into consideration before approving funding for such 

projects. While they might believe it’s a good project based on the data and chosen countermeasure, if the 

likelihood of having an obligation issue is high (such as Buy America) then they unfortunately cannot approve 

the project. Other options include working with the district or local agency to avoid or plan for unexpected 

obstacles such as in the case of right of way and the National Environmental Policy Act.

2019 crash data is still provisional and subject to change. Road type for 2019 was taken from crash reports, 

whereas for 2015 - 2018 crashes were located to roads. Given the provisional nature of 2019 data and limited 

time, that wasn't possible. Additionally, some of the roadway classification types have changed over the years.

Safety Performance Targets

Safety Performance Targets

Calendar Year 2021 Targets *

Number of Fatalities:1000.0
2020 Illinois Highway Safety Improvement Program

Page 30 of 43

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

The target was established based on a 5-year rolling average using crash data from 2015 – 2019 (as of July 8, 

2020) and a 2% reduction. IDOT’s overall goal as outlined in its SHSP is 0 fatalities and hopes that a 2% 

reduction each year will result in ultimately reaching that goal. Implementing HSIP projects is just one of the 

ways in which IDOT can meet its goal.

Number of Serious Injuries:11566.4

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

The target was established based on a 5-year rolling average using crash data from 2015 – 2019 (as of May 

28, 2020) and a 2% reduction. It should be noted that as serious injuries were not yet finalized at the time of 

analysis for 2019, they have been estimated. In addition to reaching 0 fatalities, the SHSP also calls for 0 

serious injuries, and by reducing serious injuries 2% each year, IDOT hopes to reach that goal. Implementing 

HSIP projects is just one of the ways in which IDOT can meet its goal.

Fatality Rate:0.930

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

The target was established based on a 5-year rolling average using crash data from 2015 – 2019 (as of July 8, 

2020) and a 2% reduction. As mentioned before, IDOT’s SHSP’s overall goal is 0 fatalities and hopes that a 

2% reduction each year will result in ultimately reaching that goal. Implementing HSIP projects is just one of 

the ways in which IDOT can meet its goal.

Serious Injury Rate:10.790

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

10.79 is the 2% reduction rate. It was established based on a 5-year rolling average using crash data from 

2015 – 2019 (as of May 28, 2020) and a 2% reduction. It should be noted that as serious injuries were not yet 

finalized at the time of analysis for 2019, they have been estimated. In addition to reaching 0 fatalities, IDOT’s 

SHSP also aims to reach 0 serious injuries, and by reducing serious injuries 2% each year, IDOT hopes to 

reach that goal. Implementing HSIP projects is just one of the ways in which IDOT can meet its goal.

Total Number of Non-Motorized Fatalities and Serious Injuries:1517.6

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

1517.6 is the 2% reduction rate. It was established based on a 5-year rolling average using crash data 

(pedestrian, bicyclist, and other cyclist) from 2015 – 2019 (as of July 8, 2020) and a 2% reduction. It should 

also be noted that as 2019 crash data was not yet finalized at the time of analysis, serious injury data has been 

estimated. While the majority of crashes involve motorists, IDOT still has concern for nonmotorized fatalities 

and serious injuries, and therefore has a 0 goal of fatalities and serious injuries for them as well in its SHSP. 

Implementing HSIP projects is just one of the ways in which IDOT can meet its goal.

Last year NHTSA wanted progress (met or unmet) toward a whole year’s worth of data. This year they 

changed it and wanted progress toward meeting the State’s 2020 Safety Performance Targets. This was a 

radical change. We ended up sending in Year to Date data for 1/1/2020-6/30/2020.

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

safety performance targets. 

IDOT is currently discussing with stakeholders about modifying its methodology next year. IDOT will review 

FARS and state crash data, schedule meetings with MPOs, FHWA, NHTSA, IDOT districts, SHSP and the 
2020 Illinois Highway Safety Improvement Program

Page 31 of 43

Executive Committee for discussions on current performance and future methodology. IDOT will discuss the 

impact of data-driven only targets versus a mix of data-driven and aspirational targets. IDOT will first work 

together to develop a plan and then will involve above mentioned stakeholders to receive feedback and 

constructive criticism. IDOT will consider recommendations and will present the final plan to the IDOT 

Executive Committee. The final methodology will be presented to all stakeholders. 

In the past year, targets were provided to MPO’s and BSPE provided assistance to their staffs as requested.

Past methodology involved developing using linear regression to develop statistical relations for each 

performance measures including a five-year average, ordinary least squared and exponential smoothing 

models to assess their fit with safety performance historic trends and account for future indications and 

influences. First state targets were set, followed by working with MPOs and local agencies to set targets 

specific to them and their needs. 

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. 

PERFORMANCE MEASURES TARGETS ACTUALS

Number of Fatalities 977.5 1008.8

Number of Serious Injuries 11727.4 11448.6

Fatality Rate 0.920 0.946

Serious Injury Rate 11.040 10.746

Non-Motorized Fatalities and 

Serious Injuries

1431.7 1545.0

The only two performance measures Illinois met was the number of serious injuries (11727.4 target, 11448.6 

actual) and serious injury rate (11.04 target, 10.746 actual). Illinois did not meet the number of fatalities target 

(977.5 target, 1008.8 actual), fatality rate (0.92 target, 0.946 actual), or non-motorized fatalities and serious 

injuries (1431.7 target, 1545 actual). 

In regards to the fatality and fatality rate, IDOT believes that zero is the only acceptable number for fatalities 

and serious injuries and therefore set an aggressive ideal 2% reduction rate rather than a realistic reduction 

rate like other states have. IDOT still believes that 0 is the only acceptable number, but is in talks with other 

stakeholders to perhaps adjust the targets making them more realistic instead of aggressive in hopes that 

IDOT can do a better job at meeting them. 

As for non-motorized fatalities and serious injuries, Illinois has seen an increase in pedestrian fatalities, 

particularly in urban areas such as Chicago, where the majority of non-motorized fatalities and serious injuries 

occur. In the past, IDOT completed the Pedestrian Corridor Analysis to help districts identify intersections and 

segments where there has been a pattern of pedestrian fatal and A-injury crashes. BSPE had been hoping to 

conduct a pedestrian RSA in Chicago over several blocks this summer. Unfortunately, the COVID epidemic put 

it on hold, although there's still hope to conduct it next year working with IDOT District 1, CMAP and Chicago 

DOT. Additionally, the recently completed 2020 State Safety Tiers now include fields to show overrepresented 

crash types for each location, including pedestrian and pedalcyclist to further help districts identify locations for 
2020 Illinois Highway Safety Improvement Program

Page 32 of 43

pedestrian and pedalcyclist improvements. BSPE also spoke at Bike Illinois Safety Summit on the HSIP 

application process, in an effort to encourage more HSIP applications aimed pedalcyclist or pedestrian 

improvements. 

Applicability of Special Rules

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

Yes

As seen in Question 23, $6,048,546 was programmed and $6,048,546 was obligated for HRRR funding during 

the fiscal year.

Provide the number of older driver and pedestrian fatalities and serious injuries 65 

years of age and older for the past seven years.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio 

• Change in fatalities and serious injuries 

• Other-naive before-after studies for specific projects 

• Other-Statewide fatal and serious injuries, local route fatal and serious injuries and performance 

measures by emphasis area 

• Other-Empirical Bayes (EB) methods for projects and the program 

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

the State's program level evaluations. 

While BSPE's consultants did develop an HSIP Evaluation Tool, as of the time of this report, evaluations based 

on more recent crash data has not been completed since the last report due to a lag in crash data completion, 

and BSPE's desire for at least five years of post data for analysis. Last year's evaluation found on average, 

fatalities were reduced by 20%, A-Injuries were reduced by 18%, B-Injuries were reduced by 5%, and KAB 

injury crashes were reduced overall by 10% at treated locations. 

BSPE acknowledges that program evaluation is important and an area BSPE should be working to improve on. 

BSPE has received grant funding to upgrade and replace its current HSIP SharePoint Site. Among the desired 

outcomes for the new site, is for it to be to communicate with other databases to access construction updates 

on projects, as this is something that is currently not available and makes it hard for BSPE to know if or when a 

project has gone to letting. Once an application is approved, BSPE is not informed if or when the project 

moves to letting and construction and sometimes approved projects can sit for years before moving forward 

on, which also makes it difficult to perform program evaluations. 

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
