Executive Summary

The Missouri Coalition for Roadway Safety and the Missouri Department of Transportation (MoDOT) are 

dedicated to improving safety of roadway users through education, engineering, enforcement and emergency 

medical services initiatives. Safety is one of MoDOT's core values: "Be Safe." This message is also reinforced 

in the Department’s Practical Design Guide that states, "Safety will not be compromised. Every project we do 

will make the facility safer after its completion." Additionally, "keeping our customers and ourselves safe" is a 

MoDOT Tangible Result and is regularly tracked and reviewed in MoDOT’s performance management system. 

Missouri's Highway Safety Improvement Program (HSIP) is driven by the state's Strategic Highway Safety Plan 

(SHSP). In October 2020, Missouri introduced its fifth edition of the SHSP and established a highway safety 

goal of ZERO fatalities by 2030. Show-Me ZERO: Driving Missouri Toward Safer Roads guides the State’s 

safety initiatives and addresses safety from a comprehensive standpoint including engineering, enforcement, 

education, emergency medical services, technology and public policy solutions. The SHSP focuses on 

implementing strategies that will reduce both fatal and serious injuries on Missouri roadways. 

Evidenced-based decision-making is paramount to a sound safety program. Data analysis is a critical part of 

identifying overrepresented crash types, locations, driver age, driver gender, and driver behaviors. These 

findings guide the deployment of effective and appropriate strategies to improve safety on the entire system. 

Efforts are made to analyze fatal and serious injury crashes to help discern where limited safety funding should 

be applied so that maximum safety benefits are attained. 

Missouri experienced 1,016 fatalities in 2021, which is the highest number since 2006. This spike may have 

been influenced by the COVID-19 pandemic and the increase in speeding and aggressive driving seen 

throughout the state. While the overall fatalities did rise, the benefits of Missouri's HSIP helped to mitigate this 

increase in severe crashes. This can be attributed to the systemic initiatives and high benefit spot treatments 

being deployed, as well as other efforts to change the safety culture of Missouri's motorists, such as the Buckle 

Up/Phone Down campaign.

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 overall HSIP is administered by MoDOT's Highway Safety and Traffic Division. However, the division does 

not typically identify individual projects as part of this process. Instead, HSIP funds are distributed to each of 

MoDOT's seven districts based on a three-year average of the number of fatalities and serious injuries 

occurring their areas. From there, each district identifies how their share of HSIP funds will be programmed in 

accordance with Missouri's SHSP and the latest safety research and guidance. The districts carry out the 

projects to completion. Occasionally, statewide safety projects may be carried out by the Highway Safety and 

Traffic Division. While Missouri's HSIP is led by MoDOT, each project goes through a robust planning process 

and allows input from various stakeholders. Additionally, these projects are tied to strategies identified in the 

SHSP, which involved collaboration with various partners throughout the state. 

Where is HSIP staff located within the State DOT? 

 Planning

MoDOT's Highway Safety and Traffic Division leads the HSIP reporting effort. MoDOT's District Traffic Offices 

facilitate the selection of HSIP projects and implement the HSIP program. 

With the goal that every MoDOT project makes the facility safer after completion, Design and Planning staff 

also consider safety in their efforts. 

How are HSIP funds allocated in a State? 

• Formula via Districts/Regions 

MoDOT's Highway Safety and Traffic Division also have some HSIP funds distributed to them. In January of 

2018, the Missouri Highways and Transportation Commission approved the use of a new formula for 

distributing safety funds to MoDOT's Districts. This new formula places more focus on areas where fatalities 

and serious injuries are occurring. This new distribution took effect in SFY 2021. Additionally, in past years the 

funding distribution was for a partial amount of the full HSIP funding available to Missouri. This year the 

Commission approved the full programming of HSIP funds.

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

Crash data on local roadways are included in the Missouri Statewide Traffic Accident Records System 

(STARS) managed by the Missouri State Highway Patrol (MSHP). MoDOT uses this data to evaluate all 

roadways in the state and places emphasis where severe crashes are occurring. This analysis is performed for 

both intersections and non-intersection locations. This analysis method places weight towards locations 

experiencing a higher frequency of severe crashes and identifying them as locations of higher interest. Most 

locations are on state system roadways, but there are local roadways identified on these lists as well. While the 

majority of the severe crash problem is located on the state system, non-state system needs are also 

investigated. MoDOT also communicates the locations of interest to planning entities such as the Metropolitan 

Planning Organizations and Regional Planning Commissions.

More than half of non-state system fatalities occur in four counties (Jackson, St. Louis City, St. Louis County, 

and Greene). In total, there were 305 non-state system fatalities. However, these four counties accounted for 

176 or 58% of the fatalities. In previous years, local strategic highway safety plans (SHSP) were developed for 

the top counties experiencing severe crashes. The local SHSPs identified systemic countermeasures and 

projects. 

The Missouri Coalition for Roadway Safety has a subcommittee focused on infrastructure improvement. In this 

subcommittee, several local agencies discuss implementation of key SHSP strategies, promote road safety 

assessments and local road safety plans, and share information on the latest safety research. Missouri now 

has three Vision Zero cities, which are Columbia, Kansas City, and Kirkwood.

Missouri's LTAP center continues to move safety forward. MoDOT has begun piloting a Safety Circuit Rider 

program through the LTAP center. This program provides a safety expert to work with local agencies that may 

not have the staff required for the development of a local road safety plan or identification of safety 

countermeasures for issues in their community.

Additionally, MoDOT facilitates the Transportation Engineering Assistance Program (TEAP) which allows local 

public agencies (LPAs) to receive engineering assistance for studying traffic engineering problems. 

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

Bureaus, Divisions) are involved with HSIP planning.

• Design

• Districts/Regions

• Governors Highway Safety Office

• Maintenance

• Operations

• Planning

• Traffic Engineering/Safety

There is some overlap in these selections with the way MoDOT is structured. Traffic engineering/safety could 

be included under operations. However, operations is more inclusive in other traffic areas, so both were 

selected. 

Describe coordination with internal partners.

MoDOT has focused for some time on system-wide safety solutions. Collaboration continues to take place with 

the Design Division to update MoDOT's Engineering Policy Guide, the Maintenance Division to improve 

roadsides, and the Planning Division to better evaluate and select safety needs for improvements. Training 
2022 Missouri Highway Safety Improvement Program

Page 7 of 53

opportunities are offered to the internal partners mentioned previously, in topics such as the Highway Safety 

Manual (HSM), Complete Streets, and Safe Transportation for Every Pedestrian (STEP). FHWA's Resource 

Center continues to provide training support in these subjects. Additionally, we work daily with the Highway 

Safety office to evaluate and monitor the crash types. It is vital that all areas in our department work together 

and focus on safety improvements.

MoDOT has also established a process to report the safety benefits of all projects utilizing HSIP funds as part 

of an ongoing internal assessment of Missouri's HSIP program. This assessment is used as part of an 

evaluation process for safety projects planned to be incorporated into the State Transportation Improvement 

Program.

In an effort to continue furthering safety, MoDOT's Highway Safety and Traffic division has created the SAFER 

document. The intent is for SAFER to be used to promote more safety conversations throughout the project 

development process. 

Identify which external partners are involved with HSIP planning.

• Academia/University

• FHWA

• Governors Highway Safety Office

• Law Enforcement Agency

• Local Government Agency 

• Local Technical Assistance Program

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

• Other-National Highway Traffic Safety Administration

• Other-Federal Motor Carrier Safety Administration

• Other-Emergency Services, Department of Revenue, etc

Describe coordination with external partners.

Missouri's Strategic Highway Safety Plan (SHSP) is the umbrella document that identifies emphasis areas and 

prioritizes strategies for reducing fatalities and serious injuries on all Missouri roadways. The development of 

the SHSP utilized significant involvement from external stakeholders throughout the state, including 

metropolitan planning organizations and local government agencies.

MoDOT also works with Missouri's LTAP center to continue to move safety forward. MoDOT sees benefit in 

continuing the Safety Circuit Rider program through the LTAP center. The Safety Circuit Rider helps to assist 

local public agencies in the analysis of safety issues on locally owned roads and help determine possible lowcost solutions to improve safety.

Each project in Missouri has engagement with local agencies through MoDOT’s planning framework, starting 

with locals identifying and prioritizing projects through MoDOT’s regional process for programming into the 

STIP. MoDOT also collaborates with planning partners through monthly webinars, which include a safety 

update in each webinar. This is used to let partners know about safety issues, legislation, tools, challenges, 

opportunities, resources, up to date status on fatalities and trends, as well as safety target coordination.

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

elaborate. 

Safety impacts are assessed for any project utilizing HSIP funds. These are tracked in MoDOT's internal 

project management system. This system has been updated to incorporate data required for the annual HSIP 

report, including items such as improvement category, subcategory, and SHSP relationship. This will 
2022 Missouri Highway Safety Improvement Program

Page 8 of 53

streamline the annual HSIP reporting process. Additionally, this internal project management system is being 

enhanced to collect more detailed information for any project improving safety regardless of the use of HSIP 

funds programmed on that project.

Program Methodology

Does the State have an HSIP manual or similar that clearly describes HSIP planning, 

implementation and evaluation processes?

No

MoDOT has an Engineering Policy Guide (EPG) article published online that outlines safety program 

guidelines.

All the countermeasure identification processes listed here are applicable to MoDOT's countermeasure 

selection, although they vary depending on how the safety need was identified (Systemic, Spot, RSA).

Does the State HSIP consider connected vehicles and ITS technologies? 

Yes

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

Missouri's Strategic Highway Safety Plan, Show-Me ZERO: Driving Missouri Toward Safer Roads, highlights 

several strategies to reduce severe crashes. One of these strategies is to take advantage of technology 

solutions to reduce the likelihood of crashes. This includes:

• Use intelligent transportation systems to detect and warn of high-risk or adverse conditions.

• Support ongoing implementation of crash avoidance systems in vehicles by maintaining retroreflectivity 

levels for signs and markings and by sharing traveler information and traffic control data with mobile 

providers.

MoDOT is also actively pursuing the use of autonomous Truck Mounted Attenuators (TMAs) for mobile work 

zones. A pilot project is currently underway testing an autonomous TMA that follows a lead vehicle. This pilot 

testing is just beginning its field testing stage.

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.

By MoDOT policy, any project that is funded with HSIP funds must calculate the anticipated reduction in fatal 

and serious injury crashes. This information is then used to justify and prioritize projects, to maximize the value 

of these limited safety funds. 

MoDOT is attempting to expand our use of the HSM to be performed on any project impacting safety, 

regardless of use of HSIP funds. One method that being implemented to promote this at MoDOT is the SAFER 

document. 

Additionally, MoDOT developed systemic evaluation tools for commonly used safety countermeasures. These 

tools provide information regarding the anticipated value that the systemic improvement may have, based on 

identified risk factors.
2022 Missouri Highway Safety Improvement Program

Page 20 of 53

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

elaborate.

MoDOT uses data driven safety analysis to identify the top crash types occurring in Missouri and developed a 

list of strategies focused on addressing these crash types. Additionally, MoDOT develops lists of various 

locations of interest that identify where there may be safety concerns based on various criteria, such as:

- High Severity Locations (Intersections/Range)

- Run Off Road Crash Locations (Curves and No Shoulders)

- Wet Crash Locations

- Crossed Centerline Crash Locations

Details regarding MoDOT's Safety Program can be found in MoDOT's Engineering Policy Guide 907.1.

Totals $42,440,000 $79,210,675 186.64%

One of the reasons for the difference between the total programmed funds and obligated funds is due to 

MoDOT's retroreflectivity striping and guardrail upgrades programs. Estimates for these programs were not 

included in the programmed numbers above. However, they are included in the obligated number above. 

Another item of note is the programmed and obligated 154 penalty (open container) funds. Given the fact that 

the federal fiscal year ends in September and the state fiscal year ends in June, there are some safety projects 

programmed with open container funds that could be obligated in the following state fiscal year. 

State and Local Funds were assumed to be 10 percent of the HSIP funds if other federal funds were included 

on projects for non-safety purposes.

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

the future.

MoDOT actively practices asset management to ensure the maintenance of the existing transportation 

network. Implementing new safety improvements that will add to the transportation system can be a challenge 

to fund in Districts that are unable to meet their asset management goals. It has been proposed to include 

HSIP projects into MoDOT's asset management process to ensure the safety improvements constructed will 

be able to be maintained into the future.

MO Crash data does not indicate these levels of detail in ownership of roadways at crash locations. MoDOT 

can only identify State or Other ownership. 

Provide additional discussion related to general highway safety trends.

While Missouri had been making progress in reducing the number of fatalities and serious injuries over the last 

few years, last two years saw a significant spike in severe crashes. The impact of the COVID-19 pandemic 

likely had an influence on this increase, particularly as is relates to speeding and aggressive driving. 

There have been over 100 non-motorized fatalities each year, over the last 6 years and last year alone 

Missouri experienced 135 fatalities. MoDOT has partnered with FHWA to organize Safe Transportation for 

Every Pedestrian (STEP) workshops to promote pedestrian safety initiatives.

Safety Performance Targets

Safety Performance Targets

Calendar Year 2023 Targets *

Number of Fatalities:948.2

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

Targets are based on an annual reduction needed to reach Zero fatalities by 2030. This reduction assumes 

larger decreases in future years as new safety technologies are implemented, such as autonomous vehicles. 

This target is in line with the SHSP to reduce the number of fatalities on Missouri's roadways. 

Number of Serious Injuries:4848.7

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

Targets are based on an annual reduction needed to reach Zero serious injuries by 2040. This target is in line 

with the SHSP to reduce the number of serious injuries on Missouri's roadways. 

Fatality Rate:1.212

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

The fatality rate was calculated by taking a 5-year rolling average of historical and forecasted annual fatality 

rates. Historical fatality rates were derived from observed fatality totals and estimated Annual Vehicle Miles 

Traveled (VMT). Forecasted rates were determined by using the number of fatalities performance target and 

dividing by the estimated Annual VMT. The VMT dropped significantly in 2020, by nearly 10%. In 2021 the 

VMT rebounded more than anticipated such that it is just slightly higher than 2019. It is anticipated that the 

typically estimated 1% growth per year will be sufficient moving forward. This target is in line with the SHSP to 

reduce the number of fatalities on Missouri's roadways. 

Serious Injury Rate:6.205

Describe the basis for established target, including how it supports SHSP goals.
2022 Missouri Highway Safety Improvement Program

Page 40 of 53

The serious injury rate was calculated by taking a 5-year rolling average of historical and forecasted annual 

serious injury rates. Historical serious injury rates were derived from observed serious injury totals and 

estimated Annual Vehicle Miles Traveled (VMT). Forecasted rates were determined by using the number of 

serious injuries performance target and dividing by the estimated Annual VMT. The VMT dropped significantly 

in 2020, by nearly 10%. In 2021 the VMT rebounded more than anticipated such that it is just slightly higher 

than 2019. It is anticipated that the typically estimated 1% growth per year will be sufficient moving forward. 

This target is in line with the SHSP to reduce the number of serious injuries on Missouri's roadways. 

Total Number of Non-Motorized Fatalities and Serious Injuries:499.2

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

The non-motorized fatalities and serious injuries performance target was based on the performance targets for 

number of fatalities (Zero by 2030) and number of serious injuries (Zero by 2040). An exception is made for 

instances where the baseline 5-year rolling average (2017-2021) is less than the calculated target. In this 

instance, the baseline is less than the calculated performance target, and so the baseline was used as the 

target. This target is in line with the SHSP to reduce the number of fatalities and serious injuries on Missouri's 

roadways. 

Performance Measures for Fatalities, Fatality Rate, and Serious Injuries were set based on what was reported 

in the Highway Safety Plan. 

Performance Measures for Serious Injury Rate and Non-Motorized Fatalities and Serious Injuries were set 

based on crash data available in August 2022 for use in the Highway Safety Improvement Program Annual 

Report. 

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

safety performance targets. 

Missouri's Highway Safety Office is located within MoDOT which promotes a collaborative environment 

between engineering and safety staff. MoDOT updated its Strategic Highway Safety Plan (SHSP) using a 

collaborative, team approach. The team included external partners from emergency management, FHWA, 

FMCSA, hospitals, law enforcement, Missouri Department of Revenue, MPOs, NHTSA, Regional Planning 

Commissions (RPCs), and universities. Revisions to the SHSP were shared periodically with the MPOs and 

RPCs. 

Extensive coordination occurred between FHWA, MoDOT, MPO, and NHTSA staff when setting the Safety 

Targets. Missouri safety data was reviewed for trends, along with assumptions and challenges. MoDOT 

conducts monthly calls with planning stakeholders. In 2016, a target coordinating process was presented with 

feedback and consensus from the MPOs. In March, MoDOT calculated statewide and MPO data trends for 

each safety performance measure. This information was shared and discussed with MoDOT's Executive 

Team, MPOs FHWA, and NHTSA. After review of feedback from partner groups, the methods and 

assumptions used to develop the performance targets were finalized in April. MoDOT then applied the agreed 

upon methodology to develop the safety performance targets and communicated them with the partners. 

Does the State want to report additional optional targets? 

No
2022 Missouri Highway Safety Improvement Program

Page 41 of 53

Describe progress toward meeting the State’s 2022 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 871.6 947.4

Number of Serious Injuries 4463.9 4829.2

Fatality Rate 1.119 1.236

Serious Injury Rate 5.829 6.297

Non-Motorized Fatalities and 

Serious Injuries

462.2 504.0

Based on the data available at the time of reporting, the actual 2021 performance was worse than the 2021 

targets, for each of the safety performance targets. This is primarily due to an increase in fatalities and serious 

injuries which occurred within the 5 year average reporting period. This is consistent with what was 

experienced nationally during this timeframe, meaning there were external factors, beyond the HSIP program, 

that were influencing the increase in fatalities. One of the major external factors is that of the COVID-19 

pandemic.

Although the last two years (2020 and 2021) saw increases in fatalities and serious injuries the trend is looking 

to be more positive this year (2022), as Missouri is currently seeing a decrease in sever crashes. However, this 

has still not recovered to the point that the severe crashes are below what was seen before 2020. These still 

elevated numbers, most likely, can be attributed to the increase in speeding and aggressive driving observed 

throughout the state. Additionally, Missouri's Fall 2020 state legislature repealed a helmet law for motorcyclists, 

which can be correlated to an increase in motorcycle fatalities. 

MoDOT will continue to work with the Missouri Coalition for Roadway Safety to attempting to change the safety 

culture of Missouri's motorists, specifically as it relates to the 4 emphasis areas identified in Missouri's SHSP: 

Occupant Protection, Distracted Driving, Speed and Aggressive Driving, and Impaired Driving.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio 

• Change in fatalities and serious injuries 

• Lives saved 

• Other-Evaluation of individual HSIP projects and programs 

MoDOT reports on the safety benefits, such as benefit/cost ratio and lives saved, for all projects utilizing HSIP 

funds as part of an internal assessment of their HSIP program. This assessment is used as part of a vetting 

process for planned safety projects to be incorporated into the State Transportation Improvement Program. 

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

the State's program level evaluations. 

MoDOT will evaluate specific HSIP projects to assess their effectiveness at reducing fatal and serious injury 

crashes. This information is then used to promote or discourage the use of a particular safety countermeasure. 

For systemic improvements, MoDOT tracks the change in the number of fatalities as the amount of a safety 

improvement is further deployed. This allows MoDOT to monitor the safety benefits returned on its continued 

investment of a systemic strategy. One systemic strategy evaluated was the implementation of chevrons on 

curves where advisory speeds are at least 15 mph less than posted speeds. Between 2014 and 2019, 

horizontal curve fatalities and serious injuries on minor roads decreased from 622 to 474. 

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

success of the Highway Safety Improvement Program? 

• HSIP Obligations 

MoDOT's planning office tracks the programming of safety funds to ensure they do not lapse on HSIP funds. 

There are other success indicators that MoDOT has seen some improvement, but they are not currently being 

reported on. These indicators include: 

· Increased awareness of safety and data-driven process 

· Increased focus on local road safety 

· More systemic programs

*Based on Functional Classification (MIRE 1.0 Element Number) [MIRE 2.0 Element Number]

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. 

MoDOT will use multiple methods over the next several years to meet the requirements for the collection of FDE’s on all public roads. MoDOT will prioritize these needs by addressing the Non-Local Paved roads data gaps first. 

Surface Type/Number of Lanes/one-two way operations/access control/Median Type – These data items will be addressed through the cooperative program we have with our local authorities that ensures we have complete and correct 

geospatial network. As we continue these reviews in the future, we will ask them to provide these additional four items. Also, much of this data can be collected through other sources such as aerial photography and video logging. The 

targeted completion data for the collection and storage of this data is December 31, 2023. 

The second priority will be the Local Paved Roads. 

Surface Type/Number of through lanes – These items will be collected at the same time they are collected on Non-Local Paved roads. Since geospatial reviews include all public roads, this data will have already been collected.

AADT – It is estimated that an additional 80,000 traffic count locations will be needed to fulfill this requirement. MoDOT has attempted to work with several local agencies to share traffic data, but there has been little success. Few 

agencies collect traffic data in a manner that allows the calculation of AADT. Local governments collect traffic data, often one time only, for specific purposes like signal timing. Local agencies do not have permanent sites or a history of 

short term counts available to create AADT data.

Glossary

5 year rolling average: means the average of five individuals, 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.
