Executive Summary

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

strategic approach targeted to infrastructure improvements administered by Federal Highways 

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 of these rates, 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 the preventable fatalities and serious injuries 

with federal support.

The collaborative working efforts between Strategic Highway Safety Plan (SHSP) with Highway 

Safety Improvement Program (HSIP), Highway Safety Plan (HSP), Commercial Vehicle Safety 

Plan (CVSP), Statewide Transportation Improvement Plan (STIP) - Long Range plan with 

metropolitan level is envisioned to provide consistency of data collection and management, 

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

safety performance assessment. This coordination of safety programs helps IDOT to prioritize 

safety in planning and programming stage to utilize limited funding with safety improvement 

potentials to set effective goals, targets with safety performance matrix and assessments in 

future.

HSIP is administered and monitored by the Illinois Department of 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. 

Overall the program has seen a plateau in fatalities over the last few years, but 2014 has shown 

an approximately 7% decrease compared to this time last year. Detailed crash data analysis has 

shown that fatalities and severe injuries on the state route system continue to steadily 

decrease year after year. The local system fatalities and severe injuries have decreased 8% to 

9% over 5 years from 2010 to 2014, indicating the significance of the Illinois Safety Program 

Local Roadways Initiative focusing on county wide data analysis, Local Roads FIVE PERCENT 

analysis and the development of County Strategic Highway Plans. The funding split between 

state and local routes remains the same as last year, 80/20, while IDOT continues to work with

local agencies to increase obligation rates for HSIP projects approved. Illinois continues to 

monitor progress, evaluates programs and modifies the screening, project identification and 

project approval approach to achieve Zero Fatalities on Illinois roadways.

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 MAP-21 Reporting Guidance dated February 13, 2013 and consists 

of four sections: program structure, progress in implementing HSIP projects, 

progress in achieving safety performance targets, and assessment of the 

effectiveness of the improvements. 

Program Structure

Program Administration

How are Highway Safety Improvement Program funds allocated in a State? 

Central

Describe how local roads are addressed as part of Highway Safety Improvement Program.

Twenty percent of the HSIP roadway funding is allocated to local roadways. Prior to SAFETEA-LU, local 

agencies received less than $1 million annually; in recent years, that amount has been increased to 

between $12 - $15 million annually. 

Each Illinois Department of Transportation (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 regular meetings with the MPOs to discuss safety performance targets and county SHSP 

development and implementation.
2016 Illinois Highway Safety Improvement Program

Road Safety Assessments (RSAs) are provided to local agencies free-of-charge at the request of local 

agencies. IDOT Bureau of Safety Programs and Engineering (BSPE) coordinates team members and 

facilities, provides technical analysis, presents the kick-off and team findings and prepares the RSA 

reports. 

The IDOT Bureau of Safety Programs and Engineering (BSPE) is an active participant of 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. 

After identifying increased fatalities on the local roadway system, the IDOT increased focus on local 

roadways by launching the Local Road Safety Initiative. The Local Road Safety Initiative is a multipronged approach to provide the tools and data along with program training and facilitation to organize 

local transportation safety committees. The participation continues to grow and the quality of 

applications have improved significantly Each county is provided with County Strategic Highway Safety 

Plans (SHSP) Elements that include crash data trees, Emphasis Area tables, heat maps and effective 

countermeasures and strategies to address the potential safety improvements. The county SHSPs have 

been completed for 37 counties so far. These counties represent the majority of the fatalities and 

serious injuries on Illinois roadways. 

In early 2014, IDOT developed the FIVE PERCENT location list for the local system to address high 

priority locations and support system-wide initiatives. 

In 2013, IDOT also embarked on a pilot program for nine (9) counties in the use of usRAP for county 

routes. 

The DOT coordinates safety 4E workshops that encourage coordination and training locals on HSIP best 

practices. Based on the technical support provided, local agencies apply for HSIP funds for 

implementation. The HSIP applications are reviewed by the IDOT Central Office traffic safety committee 

to approve projects, recommend changes or refinements and consult with local agencies to ensure 

safety investments address program goals.

curves. This information is provided to the Districts and local agencies through avenues such as the 

Safety Portal. 

Each District has a safety committee comprised of representative in design, planning and operations. 

This committee reviews the Safety Tier locations, systemic analysis results, performs safety data analysis 

and field reviews, and identifies potential HSIP projects based on priority and safety needs. The 

Districts review local HSIP applications and provide input and recommendations prior to submitting 

applications to IDOT Central Office.

IDOT BSPE utilized the HSIP SharePoint site to coordinate internally with Districts, Office of Planning and 

Programming and Office of Budget and Fiscal Management and other IDOT Offices, including FHWA 

Illinois Division Office. 

IDOT Bureau of Safety Programs and Engineering (BSPE) leads a Transportation Safety Committee in 

Central Office that review and approve, deny or make recommend changes to all statewide HSIP 

projects. The committee includes members of IDOT BSPE, IDOT Bureau of Design and Environment, IDOT 

Bureau of Local Roads and Streets and FHWA.

Describe any other aspects of Highway Safety Improvement Program Administration on which you 

would like to elaborate.

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

approval by a Central Transportation Safety Committee. Since 2013, the IDOT Districts have taken a 

more 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 the best and most appropriate use of HSIP funds to 

maximize results.

place in both the use fo the HSM, greater use of RSAs and systemic applications such as curves, rumble 

strips and flashing yellow arrow at intersection.

Describe any other aspects of the Highway Safety Improvement Program methodology on which you 

would like to elaborate. 

The HSIP process continues to improve each year. One area that continues to evolve is multi-year 

programing that allows Districts to establish program priorities and needs over multiple years. This helps 

to administer the program an ensure smooth and efficient use of funds on effective safety 

improvements.

FHWA published the older population in thousands 

(http://www.fhwa.dot.gov/map21/guidance/guideolder.cfm) for all the states from 2008 to 2014. As a 

result of this reporting year, the 5-year rolling average can be done for 3 years: 2012 (2008 - 2012), 2011 

(2009 - 2013), and 2014 (2010 - 2014). The bar charts shows those 3 years for 5-year rolling average.

Assessment of the Effectiveness of the Improvements (Program 

Evaluation)

What indicators of success can you use to demonstrate effectiveness and success in the Highway 

Safety Improvement Program?

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

measures by emphasis area and District

What significant programmatic changes have occurred since the last reporting period? 

None

Briefly describe significant program changes that have occurred since the last reporting period. 

Illinois has been developing and maintaining databases that will be used for project and program 

evaluation. This will supplement the statewide performance metrics that are being used to manage and 

track program successes and make changes as needed.

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g. 

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data-driven, 

collaborative process. 

Highway safety improvement project means strategies, activities and projects on a public road that are 

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location 

or feature or addresses a highway safety problem. 

HMVMT means hundred million vehicle miles traveled.

Non-infrastructure projects are projects that do not result in construction. Examples of noninfrastructure projects include road safety audits, transportation safety planning activities, 

improvements in the collection and analysis of data, education and outreach, and enforcement 

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and 

pedestrians over the age of 65 in a State increases during the most recent 2-year period for which data 

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated 

February 13, 2013. 

Performance measure means indicators that enable decision-makers and other stakeholders to monitor 

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation 

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into 

classes, or systems, according to the character of service they are intended to provide.

Strategic Highway Safety Plan (SHSP) means a comprehensive, multi-disciplinary plan, based on safety 

data developed by a State Department of Transportation in accordance with 23 U.S.C. 148. 

Systematic refers to an approach where an agency deploys countermeasures at all locations across a 

system.

Systemic safety improvement means an improvement that is widely implemented based on high risk 

roadway features that are correlated with specific severe crash types. 

Transfer means, in accordance with provisions of 23 U.S.C. 126, a State may transfer from an 

apportionment under section 104(b) not to exceed 50 percent of the amount apportioned for the fiscal 

year to any other apportionment of the State under that section.
