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 motor vehicle related fatalities and serious injuries, as well as the fatality and 

serious injury rates 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; last updated 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 updated SHSP was kicked off in early 2018 and has involved over a hundred 

stakeholders representing multi-disciplinary areas. 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.

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 serious crashes economically using the IDOT benefit-cost evaluation 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 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.

Where is HSIP staff located within the State DOT? 

 Other-Bureau of Safety Programs and Engineering

How are HSIP funds allocated in a State? 

• Other-Central Office via Statewide Application Process

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

Twenty percent of the HSIP roadway funding (or $12M to $15M annually) is allocated to local roadways. 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 regular 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.

• Operations

• Planning

• Other-Safety Programs and Engineering

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, Operations, 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 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.

Identify which external partners are involved with HSIP planning. 

• FHWA

• Local Government Agency 

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

• Other-Local Agencies

• Other-NHTSA

• Other-NACE

Describe coordination with external partners. 

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.

Describe HSIP program administration practices that have changed since the last 

reporting period. 

IDOT continues to improve processes to make it easier and more effective to allocate funds appropriately to

local agencies to reduce fatalities and serious injuries on all public roadways. In particular, IDOT lead a pilot 

study to identify corridors that had an overrepresentation of run-off-the-road serious crashes and would have a 

positive benefit-cost for shoulder widening. Corridors were identified and discussed with several local 

agencies. Based on local agency discussions, if the local agency wanted to proceed with improvements IDOT 

helped to develop the project and allocate HSIP funds for implementation. IDOT has also been reviewing 

serious injury crashes at signalized intersections and signal phasing projects at key locations to encourage 

signal phasing changes from permissive and permissive / protected to protected only left turn phasing.

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 

data is now required to develop project and program level evaluation assessments to maximize the program 

and achieve the greatest results.

What is the justification for this program? 

Run off the road cashes are the leading severity crashes on the Local System. The State of Illinois was also in 

non-compliance for High Risk Rural Roads. Many downstate counties have not been submitting HSIP Projects 

when funds are available. The pilot of was to help counties identify corridors that have significant number of 

run off the road crashes and cost effective solutions to address those crashes. 

Methodology?

Pilot Counties were given a county wide map identifying ROR Corridors. A table was with the map showing 

crash data, miles, recommended countermeasures and estimated B/C.

What percentage of HSIP funds address systemic improvements? 

 30

 HSIP funds are used to address which of the following systemic improvements? 

• Add/Upgrade/Modify/Remove Traffic Signal
2019 Illinois Highway Safety Improvement Program

Page 13 of 47

• Cable Median Barriers

• High friction surface treatment

• Horizontal curve signs

• Install/Improve Signing

• Pavement/Shoulder Widening

• Rumble Strips

What process is used to identify potential countermeasures? 

• Crash data analysis

• Data-driven safety analysis tools (HSM, CMF Clearinghouse, SafetyAnalyst, usRAP)

• Engineering Study

• Road Safety Assessment

• SHSP/Local road safety plan

• Stakeholder input

Does the State HSIP consider connected vehicles and ITS technologies? 

No

Although HSIP funds aren't used for these items, IDOT has been implementing changeable message signs, 

Smart Work Zones and improved communication to reduce secondary incidents at high priority locations.

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. Statewide projects that have utilized HSIP funding and were 

completed between 2007 and 2015 were evaluated using simple before and after analysis, similar to those 

outlined in the HSM. 

Describe program methodology practices that have changed since the last reporting 

period. 

IDOT and FHWA-IL conducted a joint process review on the HSIP application process for local agencies, to 

identify areas for growth. As part of the process, IDOT has improved and streamlined processes to support 

HSIP on local roadways. One example new program is the run-off-the-road pilot study which will be expanded 

statewide to assist local agencies in identifying candidate locations and countermeasures to reduce serious 

ROR crashes.

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 Road Safety Assessment (RSA) process. An RSA 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 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. 

IDOT Districts and 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 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 and obtaining right-of way can also be time consuming and impact the 

project delivery schedule. Depending on the complexity of the project, obtaining required permits can impact 

the project timeline. Obtaining community approval and acceptance of some treatments has been a focus. 

Education of flashing yellow arrows, roundabouts and rumble strips in advance of construction have been 

helpful for increasing public understanding and acceptance of safety countermeasures.

Effective, July 24, 2015, Illinois Grant Accountability and Transparency Act (GATA) was signed into law to 

require the adoption and implementation of a comprehensive set of standards that mandate accountability and 

transparency throughout the entire life cycle of a grant. Illinois is the first and only state to provide such 

legislation in the nation. GATA requires local agencies to provide project information in advance of HSIP 

approvals and continue to provide project financial reporting from planning to construction. Some local 

agencies have indicated that the GATA process and meeting the ten percent HSIP match have been 

challenging. For additional information on GATA see https://www2.illinois.gov/sites/GATA/Pages/default.aspx

Provide additional discussion related to general highway safety trends. 

From 2013 to 2017, there was a 10% increase in fatalities (991 in 2013 to 1090 in 2017). In contrast, there was 

a 2.3% decrease in serious injuries (12,300 in 2013 to 12,023 in 2017) from 2013 to 2017.

Safety Performance Targets

Safety Performance Targets 

Calendar Year 2020 Targets *

Number of Fatalities:985.0

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

Total traffic fatalities in Illinois are a main concern and reduction of total fatalities remains the primary 

goal of the Department as stated in the SHSP. Data from 2010-2018 were utilized to create a fiveyear rolling average for each year. For example, the rolling average for 2013 was computed by 

averaging 2009, 2010, 2011, 2012, and 2013. A rolling average is commonly used to smooth out 

short-term fluctuations and highlight longer-term trends or cycles. To project performance targets for 

Illinois, a two-percent reduction was utilized. The goal for 2019 was computed by reducing 2018 by 

two-percent and 2020 was computed by reducing 2019 by two-percent. A two-percent reduction was 

used due to the fact the five-year rolling averages from 2014 to 2018 have an upward linear trend as 

seen through the linear regression line. The goal for Illinois is to reach zero fatalities per year and 

using a two-percent reduction will enable the state to reach its goal. The mission of the SHSP is to 

develop, implement and manage a data-driven, integrated, multi-stakeholder process to reduce 

traffic-related deaths and life-altering injuries on all public roads in Illinois. Each of the emphasis 

areas are prioritized and based on the greatest opportunity to reduce fatalities and serious injuries.

Number of Serious Injuries:11668.7

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

For Total Serious Injuries in Traffic Crashes, five-year rolling averages were created for each year 

from 2013-2017 since 2018 was not yet available. 2018 was then estimated through the use of a 

trendline and the total average of 2014 through 2018. Although this resulted in a downward trend, the 

reduction of fatalities by 2020 was not sufficient to be greater than two-percent; therefore, a twopercent reduction was used which sets a target of 11,668.7 total serious injuries in 2020. Reducing 

serious injuries is a goal set in the SHSP along with the reduction of fatalities. The mission of the 

SHSP is to develop, implement and manage a data-driven, integrated, multi-stakeholder process to 
2019 Illinois Highway Safety Improvement Program

Page 34 of 47

reduce traffic-related deaths and life-altering injuries on all public roads in Illinois. Each of the 

emphasis areas are prioritized and based on the greatest opportunity to reduce fatalities and serious 

injuries.

Fatality Rate:0.910

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

Similar to previous target selection methods, five-year rolling averages were used from 2014-2018 for 

the Total Traffic Fatality Rate. Since the 2018 Vehicle Miles of Travel (VMT) data from FHWA were 

not available, the 2018 state VMT data published by IDOT were used to calculate the fatality rate. 

Like the Total Traffic Fatalities, the data show an upward trend. To move toward the goal of zero 

fatalities, a two-percent reduction is applied annually resulting in the projected rate of 0.91 per 100 

million VMT in 2020. Reducing the fatalities and the fatality rate in Illinois are a main concern and a 

primary goal of the Department as stated in the SHSP. The mission of the SHSP is to develop, 

implement and manage a data-driven, integrated, multi-stakeholder process to reduce traffic-related 

deaths and life-altering injuries on all public roads in Illinois. Each of the emphasis areas are 

prioritized and based on the greatest opportunity to reduce fatalities and serious injuries.

Serious Injury Rate:10.800

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

For Total Serious Injury Rate per 100M VMT, five-year rolling averages for Total Serious Injuries (as 

previously shown) were divided by five-year rolling averages for VMT for 2014 through 2018. Since 

Federal VMT was available for all years except 2018, state VMT was used for 2018. Linear 

regression for the projected values of 2019 and 2020 only show a slight downward trend in the 

reduction of Total Serious Injury Rate by 2020 of 11.07 per 100 M VMT. Instead, a two-percent 

reduction was used, bringing the target to 10.80 per 100 M VMT in 2020. Reducing the serious 

injuries and the serious injury rate in Illinois are a main concern and a primary goal of the Department 

as stated in the SHSP. The mission of the SHSP is to develop, implement and manage a data-driven, 

integrated, multi-stakeholder process to reduce traffic-related deaths and life-altering injuries on all 

public roads in Illinois. Each of the emphasis areas are prioritized and based on the greatest 

opportunity to reduce fatalities and serious injuries.

Total Number of Non-Motorized Fatalities and Serious Injuries:1456.2

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

For the Number of Nonmotorized Fatalities and Serious Injuries, five-year rolling averages were 

created for each year from 2013-2017 since 2018 was not yet available. Next, a trendline was created 

based on the data from 2013-2017. Using the trendline, the value for 2018 was calculated. 2018 was 

further estimated by taking this trend value for 2018 and averaging it with the total average of 2014 

through 2018. This resulted in an upward trend, moving Illinois away from the goal of reaching zero 

fatalities so a two-percent reduction was used. This sets the target to 1,456.2 Nonmotorized fatalities 

and serious injuries in 2020. The mission of the SHSP is to develop, implement and manage a datadriven, integrated, multi-stakeholder process to reduce traffic-related deaths and life-altering injuries 

on all public roads in Illinois. Each of the emphasis areas are prioritized and based on the greatest 

opportunity to reduce fatalities and serious injuries.

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

safety performance targets. 

The IDOT Bureau of Safety Programs and Engineering lead safety performance target setting coordination and 

concurrence efforts. BSPE initiated the process by developing statistical relationships for each performance 

measure using linear regression, linear regression with 5 year averages, ordinary least squared and 

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

indicators and influences. Outside indicators considered include trends related to population, population by 

age, licensing by age and geography, mode shift, oil futures, pending legislation, funding and budgets for 

enforcement, education and engineering. In addition to historic trends and outside influences, Illinois 

considered long term goals and the vision of achieving zero fatalities on all public roadways. In addition to 

statewide metrics, BSPE developed initial safety performance calculations for each of the MPOs statewide for 

their use in target setting.

BSPE convenes meetings with the Highway Safety Office and HSP program managers, Districts and MPOs to 

discuss the initial findings and safety target recommendations. After obtaining input, BSPE met with the SHSP 

Executive Committee to share findings and recommendations. The SHSP Executive Committee provided 

feedback and concurrence on the safety targets. After state targets were set, IDOT Districts worked with MPOs 

to set local safety performance targets. A majority of the MPOs supported the state targets but some MPOs 

opted for tailored performance measures related to non-motorized or specific crash types.

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2018 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. 

Fatalities: IDOT set targets to decrease fatalities by two percent annually, despite indicators and an increasing 

trend for years 2015, 2016 and 2017. While targets may not be met for 2018, the state is making progress as 

seen in fatality reductions between 2018 and 2019. The longer term trajectory appears to be decreasing. 

Efforts have been made to specifically focus on implemented projects and adjustments to the program to 

address system needs. 

Serious Injuries: IDOT set targets to decrease serious injuries by two percent annually, despite indicators and 

an increasing trend for years 2015 and 2017. There were decreases in 2014 and 2016. 2018 data will be 

needed to assess impacts relative to targets. 

Fatality rate: IDOT set targets to decrease fatality rate by two percent annually, despite indicators and an 

increase in years 2015 and 2017. There were decreases in 2016 and 2018. 

Serious injury rate: IDOT set targets to decrease serious injury rate by two percent annually, despite indicators 

and an increase in years 2015 and 2017. There were decreases in 2016 and will need to monitor 2018 to 

determine the impact on targets.

Non-motorized fatalities and serious injuries: IDOT set targets to decrease non-motorized fatalities and serious 

injuries by two percent annually, despite indicators and an increase in years 2015 and 2017. There were 

decreases in 2016 and will need to monitor 2018 to determine the impact on targets.

Applicability of Special Rules 

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

No 

As directed by the FHWA, "...States triggers the HRRR Special Rule if the fatality rate on the rural roads in the 
2019 Illinois Highway Safety Improvement Program

State increases over the most recent 2-year period for which data is available." The two most recent, complete, 

and available years of FARS data for Illinois are 2016 and 2017. Also, the guidelines provided by FHWA 

indicates that "...HRRRs are limited to the functional classifications of rural major and minor collectors and rural 

local roads...". The source for both of these statements can found in the following link: 

https://safety.fhwa.dot.gov/hsip/hrrr/

After considering this guidance, the High-Risk Rural Road (HRRR) calculations for the State of Illinois are 

listed below (note: this is for the 2019 reporting period). 

Since the 2017 HRRR fatality rate is lower than the 2016 HRRR fatality rate, Illinois does not fall into the 

penalty category for the 2019 reporting period.

For 2016:

Fatalities on Rural, Minor Collector: 8

Fatalities on Rural, Major Collector: 117

Fatalities on Rural, Local Road or Street: 87

Sum of fatalities on these three Functional Classes: 212

HMVMT on Rural, Minor Collector: 5.52

HMVMT on Rural, Major Collector: 40.66

HMVMT on Rural, Local Road or Street: 32.73

Sum of HMVMT on these three Functional Classes: 78.91

2016 HRRR fatality rate: 212 / 78.91 = 2.68

For 2017:

Fatalities on Rural, Minor Collector: 8

Fatalities on Rural, Major Collector: 109

Fatalities on Rural, Local Road or Street: 62

Sum of fatalities on these three Functional Classes: 179

HMVMT on Rural, Minor Collector: 5.38

HMVMT on Rural, Major Collector: 39.96

HMVMT on Rural, Local Road or Street: 32.57

Sum of HMVMT on these three Functional Classes: 77.91

2017 HRRR fatality rate: 179 / 77.91 = 2.29

Evaluation

Program Effectiveness

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio

• 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

The State measures the effectiveness of the HSIP program using two primary methods:

1. Executive Level using Benefic Cost Ratios (BCR): The BCR is calculated as total benefit divided by 

total project cost in today’s dollars. The total benefit is defined as the difference between the average 

crash cost between before and after periods over the service life of the project. A statewide HSIP 

program evaluation study was performed for projects awarded in 2007 and after and completed by 

2015. These projects were evaluated using crash data from 2005-2016 and at least two years of before 

and two years of after data for each project. For the study crash costs are considered as ~$6M for fatal, 

~$300K for A injury, and ~$120K for B injury crashes and results were presented at the aggregate 

program level. 

2. Treatment Level using Actual Crash Reduction: While the BCR provides an executive overview of the 

HSIP performance, the actual crash reductions provide a more detailed assessment of the performance 

for each treatment by crash types and/or IL SHSP Emphasis Area. The actual crash reductions are 

defined as the ratio of the average crash frequency in the after period by before period. The actual 

crash reductions are naïve CMFs and depending on the sample size, provide an estimate of the safety 

performance of the treatments. 

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

the State's program level evaluations. 

HSIP projects awarded after January 1, 2007 and completed before January 1, 2015 include more than 370 

contracts, over 2100 miles of roadway, over 500 intersections, and more than 260M HSIP dollars. The 

estimated safety benefit of these investments is estimated between $3.5B and over $7B depending on the 

crash cost source. $3.5B is based on the 2010 HSM comprehensive crash costs grown to the 2016 annual 

equivalent costs of $6.2M for fatal crashes, $336k for serious injury crashes (A type injury severity) and $123k 

for evident injury crashes (B type injury severity). Over $7B is based on 2019 National Safety Council 

Comprehensive Costs of $10.5M for fatal crashes, $1.1M for serious injury crashes (A type injury severity) and 

$318k for evident injury crashes (B type injury severity).

The overall safety benefit is based on the observed reduction in crash frequency for the treated sites over the 

service life of the projects which is equivalent to a BCR of greater than 9. In addition to BCR which provides a 

measure of effectiveness on an executive level, IDOT also uses the actual crash reductions to track the overall 

impact of HSIP funds on treated sites. Based on the evaluation results, in average, treated sites have observed 

20% reduction in their K crashes, 18% reduction in A injury crashes and more than 5% reduction in B injury 

crashes or a 10% overall reduction on KAB injury crashes.

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

success of the Highway Safety Improvement Program? 

• Other-Improving and coordinating infrastructure and behavior strategies to maximize benefits

In addition to measures of effectiveness described in Q40 and Q41, IDOT tracks the total KAB crashes and 

fatalities statewide, by land use, jurisdiction, emphasis area, crash type, crash cause, crash time, vehicle type, 

and more to identify trends. The identified trends will be further studied, and proper actions will be made to 

mitigate them.

*Based on Functional Classification

Describe actions the State will take moving forward to meet the requirement to have complete access to the MIRE fundamental data elements on all public roads by September 30, 2026. 

Illinois has all the required MIRE fundamental data elements. Based on the results of the Illinois roadway Data improvement program (RDIP) assessment that was completed in early 2018, Illinois is one of the few states where the MIRE 

fundamental data elements are collected.

Did the State conduct an HSIP program assessment during the reporting period? 

No

IDOT is continuously assessing the HSIP program and making adjustments to improve effectiveness and streamlining processes. These efforts will continue through 2019 and policy changes are anticipated in 2020.

When does the State plan to complete its next HSIP program assessment.
