Executive Summary 

The Highway Safety Improvement Program (HSIP) is a data-driven, performance based, strategic approach 

targeted to infrastructure improvements administered by the Federal Highway Administration (FHWA). Illinois 

has set its target to reduce the frequency of fatalities and serious injuries, as well as the exposure rates of 

fatalities and serious injuries per million vehicle miles traveled. In addition to these rates, the Illinois 

Department of Transportation (IDOT) has identified and prioritized safety emphasis areas where performance 

measures are also narrowed down by functional class of roadways to understand the safety problems and 

implement appropriate countermeasures to curb preventable fatalities and serious injuries with federal support.

The collaborative working efforts between the Strategic Highway Safety Plan (SHSP; FHWA approved on 

7/28/2017) HSIP, Highway Safety Plan (HSP), Commercial Vehicle Safety Plan, and Statewide Transportation 

Improvement Plan (STIP) are envisioned to provide consistency of data collection and management, integrated 

safety initiatives, and identification of data-driven performance measures with safety performance assessment. 

The implementation of the SHSP was kicked off in early 2018 and has involved over a hundred stakeholders 

representing multi-disciplinary areas. There are nine working groups that represent 16 IL SHSP emphasis 

areas. Each of the EA working groups are meeting on a regular basis to develop and implement IL SHSP EA 

action plans. The action plans are coordinated with and endorsed by the Executive Safety Committee. This 

coordination of safety programs helps IDOT prioritize the safety in planning and programming stage and use 

limited funding with safety improvement potential to set effective goals, targets with safety performance matrix, 

and assessments in the future. IDOT also recently established the Fatality Reduction Task Force to bring 

additional attention and focus to the reduction of fatalities on Illinois roadways. As part of this effect, Illinois is 

hosting the first Distracted Driving Summit on October 30, 2018.

HSIP is administered and monitored by the IDOT Bureau of Safety Programs and Engineering (BSPE). IDOT 

works with safety partners to direct limited program dollars to areas with the greatest potential for safety 

improvement on the transportation system. IDOT uses safety performance functions and the systemic 

approach for identifying areas of improvement. Projects are selected based on their potential to reduce fatal 

and severe crashes economically using the IDOT benefit-cost evaluation tool. Illinois has made significant 

progress in tracking HSIP projects through planning, design and construction to develop databases and tools 

for evaluating treatments and the effectiveness of the overall HSIP program. Evaluation tools utilize both naïve 

and empirical bayes methods to account for data variations. While analysis results are preliminary, these 

efforts support the development of sustainable evaluation processes that will be will be integral to achieving 

optimum safety performance.

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 Illinois HSIP policy identifies the process for data analysis, project application, project review, and 

approval. See the IDOT website for details (http://www.idot.illinois.gov/transportation-system/localtransportation-partners/county-engineers-and-local-public-agencies/funding-opportunities/highway-safetyimprovement-program).

The policy is being updated and will include analysis tools and resources as well as improved guidance to 

direct the program to projects that will have the greatest opportunity to reduce fatalities and serious injuries 

with additional focus on locally owned roadways.

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

Twenty percent of the HSIP roadway funding is allocated to local roadways. Prior to the Safe, Accountable, 

Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), local agencies received less

than $1 million annually; in recent years, that amount has been increased between $12 to $15 million annually. 

Each IDOT District has a traffic safety committee that coordinates with the IDOT Bureau of Local Roads and 

local agencies to provide technical support. Illinois leads meetings with the Metropolitan Planning 

Organizations (MPOs) to discuss safety performance targets and county SHSP development and 

implementation. The IDOT BSPE is an active participant in the Illinois Association of County Engineers Traffic 

and Safety Committee to discuss the SHSP, HSIP, data issues, and ways to advance transportation safety in 

Illinois on local roadways.

The Local Technical Assistance Program is part of the Local Aid Programs office.

Describe coordination with internal partners.

The Central Office Traffic Safety Committee is responsible for reviewing, recommending changes and/or 

approving or declining HSIP applications. The Central Office Traffic Safety Committee includes members from 

BSPE, Design, Planning, Local Aid, and the FHWA Division Office.

The Local Aid office works with each of the District Local Aid offices and local agencies to develop, review, and 

submit HSIP applications to BSPE.

District traffic engineering and safety staff develop state route HSIP applications by using BSPE safety analysis 

tools to evaluate the roadway network, identify priority locations, assess crash data and contributing factors, 

determine recommended proven strategies, and prepare the HSIP application including benefit-cost 

assessment. District traffic engineering and safety staff conduct basic evaluation assessments for HSIP 

projects and coordinate with district design, operations and maintenance during the planning process.

District staff work closely with local agencies to develop their safety program and the District Local Aid office 

submits the applications to Central Local Aid office.

Local agencies conduct analysis and utilize BSPE-provided tools to support HSIP project development and 

applications. Local HSIP applications are submitted to the District Local Aid office for submittal to the Central 

Local Aid office. In some cases, the MPO supports local agency data analysis, application development, and 

evaluation after implementation. BSPE manages the HSIP program and leads the coordination with all 

partners.

Describe coordination with external partners.

The state of Illinois is committed to achieving a safer transportation system for the public. Stakeholder 

involvement and commitment is crucial. Stakeholders represent the 4E areas - engineering, enforcement, 

education, and emergency medical services and include multi-modal federal and state agencies, MPOs, 

regional safety coalitions, and local agencies. Stakeholders have provided input on the crash trends, locations 

with potential improvement and strategies based on their knowledge and current initiatives.

The FHWA Illinois Division office partners with Illinois on various safety initiatives, including review of HSIP 

applications for funding approval.

The Illinois DOT meets with MPOs regularly to support the safety program The MPOs work with local agencies 

to provide leadership and technical expertise.

Have any program administration practices used to implement the HSIP changed since the last reporting 

period?

No

Are there any other aspects of HSIP Administration on which the State would like to elaborate?

Yes

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

The Districts submit HSIP applications through the HSIP SharePoint site and the local agencies submit paper 

copies for review and approval by a Central Office Traffic Safety Committee. Since 2013, the IDOT Districts 

have taken an active role in supporting the local roadway safety program. If there are large HSIP funding 

requests or longer term projects, the committee may recommend that a Road Safety Assessment be 

conducted to identify low cost safety improvements that could be implemented quickly along with verification of 

the longer term, high cost projects to ensure appropriate use of HSIP funds. The HSIP policy is being updated 

to improve project submittals and to encourage the use of highway safety tools such as Safety Tiers, the 

Highway Safety Manual and the Illinois State and Local Strategic Highway Safety Plans. Additional emphasis 

has been placed on project and program evaluation. The HSIP program database includes project letting, 

locations, project type and cost along with before and after crash data to be used for evaluation. Additional

Does the State HSIP consider connected vehicles and ITS technologies? 

Yes

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

ITS strategies are considered for safety improvements. These may include changeable message signs, Smart 

Work Zones, improved communication to reduce secondary incidents among other proven and effective 

strategies. Connected vehicles and their safety impact are being considered throughout the Department, but 

much of the focus has been on addressing current needs through low cost proven effective safety treatments.

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.

HSM safety performance functions are used to develop safety tiers for planning and programming of projects. 

Districts utilize the HSM to diagnose and analyze crash data to identify potential countermeasures. 

Countermeasure effectiveness is determined using the CMF Clearinghouse and projects are assessed using 

the benefit-cost approaches outlined in the HSM. Many of the projects are evaluated after implementation 

using HSM analysis approaches.

Are there any other aspects of the HSIP methodology on which the State would like to elaborate?

Yes

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

The HSIP Policy Memorandum references a safety analysis process for HSIP candidate projects that should 

be similar to the RSA/RSR process. An RSA/RSR is a data-driven systematic process that applies crash data 

and identified contributing factors in tying the target severe crashes to each countermeasure. The RSA/RSR 

safety analysis process has become a more prominent aspect for many HSIP submittals when larger dollar 

amounts would be involved. IDOT has a draft RSA Policy Memorandum in place that supports HSIP.

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

Local agencies have a variety of challenges that delay obligating federal funds, such as scoping and design 

and the overall federal aid process. When federal funds are involved, the engineering agreement and joint 

funding agreement processes severely hamper the timeline for federal HSIP projects. Depending on the 

complexity of the project, the federal National Environmental Policy Act process for environmental review can 

impact the project timeline. Again, depending on the complexity of the project, obtaining some required permits 

can impact the project timeline. The Department is experimenting with a revised signature process for approval 

of project agreements, which should simplify and expedite this process. We are always looking for ways to 

expedite the environmental review process, when required.

For locally owned roadways, the GATA process and requirements have been challenging. In many cases, it is 

also difficult for local agencies to meet the ten percent HSIP match requirement. 

Does the State want to elaborate on any other aspects of it’s progress in implementing HSIP projects?

No

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

targets. 

Executive meetings and coordination sessions were held with the stakeholders to discuss the safety 

performance and set targets for the measures. Each of the MPOs has taken a different approach to target 

setting. Many of the MPOs support the statewide targets, while others have added a bicycle and pedestrian 

safety measure and a few MPOs are working on integrating performance setting and performance measures 

into the decision making process for planning and programming projects.

Does the State want to report additional optional targets?

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 

Enter additional comments here to clarify your response for this question or add supporting information.

IDOT is in the process of developing and refining procedures, databases and calculations to track HSIP 

projects through approvals, planning, design and construction for evaluation of treatments and HSIP program 

effectiveness. Projects currently included in the tool reflect HSIP projects constructed between 2007 and the 

present on state and locally owned roadways. Evaluation tools utilize both naïve and empirical bayes methods 

to account for data variations.

Based on the measures of effectiveness selected previously, describe the results of the State's program 

level evaluations.

The results include: 1) The number of fatalities and serious injuries, the percent change of fatalities and serious 

injuries. 2) Naive before-after studies for HSIP program investment. 3) Empirical Bays studies for program 

investment 4) Benefit - cost analysis for program and project investment 5) Crash Modification Factor (CMF) 

for specific treatments 

Evaluation results of the HSIP program and specific treatments are being reviewed and will be provided in the 

next reporting cycle.

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

Highway Safety Improvement Program?

Crash data is currently being collected for HSIP projects tracking and evaluation. Before and after evaluations were performed for projects implemented in 2011 and 2012 using crash data from 2008 to 2015. The number of fatal and 

serious injury crashes decreased by nearly 9 percent for projects on all routes, and it decreased by 15 percent for projects on state routes only. On all routes, the number of fatal and serious injury crashes showed a reduction of over 21 

percent for roadway departure projects.
