Executive Summary

The Highway Safety Improvement Program is administered and monitored by the Illinois Department of 

Transportation Bureau of Safety Engineering. 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 15% 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 increased slightly, 

sparking 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.

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

After identifying increased fatalities on the local roadway system, the Illinois Department of 

Transportation increased focus on local roadways by launching the Local Road Safety Initiative. The Local 

Road Safety Initiative is a multi-pronged approach to provide the tools and data along with program 

training and facilitation to organize local transportation safety committees. Each county is provided 

with County Strategic Highway Safety Plans 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 with the remaining 65 

plans targeted for completion in 2015. IDOT has identified site specific improvements using the FHWA 
2014 Illinois Highway Safety Improvement Program

3 

Systemic Tool for 8 counties to date. In early 2014, IDOT prepared the FIVE PERCENT location list for the 

local system to address high priority locations. In 2013, IDOT also embarked on a pilot program for 8 

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 in IDOT Central Office to approve projects. The 

participation continues to grow and the quality of applications have improved significantly.

Governors Highway Safety Office

Other: Other-Local agencies

Briefly describe coordination with internal partners. 

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

This committee reviews crash data, performs 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 Bureau of Safety Engineering leads a Transportation Safety Committee in Central Office that 

review and approve, deny or make recommend changes to statewide HSIP projects. The committee 

includes members of IDOT BSE, IDOT Office of Planning and Programming, IDOT Bureau of Local Roads 

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.

Discuss impediments to obligating Highway Safety Improvement Program funds and plans to 

overcome this in the future. 

IDOT programs HSIP funds several years in advance where possible to allow lead time for planning, 

design and implementation. At the local level, funds must be obligated within two years to avoid 

unspent funds. IDOT is preparing county safety plans and hosting local safety workshops to improve the 

quality and quantity of HSIP involvement at the local level. IDOT continues to grow awareness of

funding and program implementation at the local level and IDOT Districts are increasing their 

participation and support for local agency HSIP projects. 

Describe any other aspects of the general Highway Safety Improvement Program implementation 

progress on which you would like to elaborate.

The systemic approach continues to be a growing and integral part of the HSIP program. IDOT has tied 

targets and safety analysis data more directly to projects and implementation outcomes. The use of 

HSM and quantitative decision making is becoming more prevalent in project programming decisions 

related to freeways and interchanges.

Describe any other aspects of the general highway safety trends on which you would like to elaborate. 

Illinois has prepared trend lines and performance metric setting for each of the SHSP emphasis areas. 

Based on the results, Illinois has identified priority Emphasis Areas. Priority One is roadway departure, 

unrestrained, impaired, and intersections. Priority Two is speeding/ aggressive, heavy vehicle, younger 

driver, older driver, pedestrian and motorcycle. Priority Three is work zone, pedacyclist, train and 

distracted/ drowsy/ fatigue. For each of the areas, Illinois has identified trends and key strategies. For 

example, crashes on curves represent roughly 10% of all fatalities and approximately 30% of all roadway 

departure crashes. As a result, Illinois DOT has conducted a statewide study to identify the top 50 curves 

per district for additional analysis and safety enhancements such as lighting, high friction surface 

treatments and delineation.

Describe any other aspects of the overall Highway Safety Improvement Program effectiveness on 

which you would like to elaborate. 

Overall, the fatalities and severe injuries in Illinois have continued on a downward trend. The downward 

trend has been more significant for the state roadway system versus the local roadway system and for 

roadway departure. Systemic treatments have been very effective for rural areas with few severe crash 

clusters.
