2. Executive Summary

North Carolina recognizes traffic crashes as a significant public safety and health problem that continues 

to challenge the state. In 2015, there were over 270,000 reported traffic crashes that resulted in 

1,386 lives lost and over 120,000 injuries on our roadways. The socioeconomic impact of these crashes is 

severe, resulting in a loss of over $24.2 billion to the economy of North Carolina annually. This impact 

translates to a crash cost to the state of over $2.7 million every hour and approximately $66 million 

every day and a staggering social impact as well. North Carolina has established a vision to have a multidisciplinary, multi-agency highway safety approach to research, planning, investigation, design, 

construction, maintenance, operation and evaluation of transportation systems, which results in 

reduced fatalities, injuries and economic losses, related to crashes. In addition, there is a coordinated 

strategic effort to address emerging safety issues. The Executive Committee for Highway Safety recently 

met to reexamine their goals. The goal of the updated 2014 North Carolina Strategic Highway Safety 

Plan is a 50% reduction in fatalities and serious injuries by 2030 which represents an annual 3% 

reduction.

This “HSIP Report” summarizes North Carolina DOT’s implementation and effectiveness of its Highway 

Safety Improvement Program. These reports satisfy the requirements under Title 23 of the Code of 

Federal Regulations, Part 924 (23 CFR 924). The NCDOT Rail Division is developing the “Railway-Highway 

Crossing Report” as a separate report submission. North Carolina DOT has opted to use the 2015 

Calendar Year as the reporting period for the “HSIP Report”; however, some of our 2016 plans, goals, 

measures, and methods are included in this report.

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 MAP21 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.

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

In North Carolina, the local county governments are not responsible for the maintenance of 

rural highways. The NCDOT highway network covers nearly 80,000 roadway centerline miles 

which includes rural roadways classified as local; municipal governments maintain some 

downtown streets, residential streets and subdivision roads.

Several Pilot Communities including several Planning Organization staff have been formally 

trained in identifying low cost countermeasures with the ultimate goal of reducing fatalities and 

serious injuries in their cities. Technical training included understanding crash data, identifying 

potential treatment locations, preparing collision diagrams, selecting countermeasures, and 

evaluating those countermeasures. Quarterly conference calls are being held to allow city 

representatives to brainstorm ideas and offer feedback on the program. A process was 

established to federally fund some of these projects through the Local Programs Management 

Office (LPMO). By training these municipalities to analyze, identify treatments, and set up and 

evaluate projects, the municipalities should see reductions in the severity and number of 

crashes on their roadways.

NCDOT receives crash data from the Department of Motor Vehicles and has the capability to 

identify potentially hazardous locations on all publicly traveled North Carolina roadways.

5. Identify which internal partners are involved with Highway Safety Improvement Program planning.

6. Briefly describe coordination with internal partners. 

The design, planning, and operations units within NCDOT play a significant role within the 

Strategic Highway Safety Plan. These units utilize safety data during their planning phase in 

many ways. NCDOT's Policy to Projects process uses data regarding pavement condition, traffic 

congestion and road safety, as well as input from local government and NCDOT staff to 

determine transportation priorities. MPO's and RPO's utilize traffic crash data to develop and 

prioritize transportation plans. Many resurfacing projects are utilizing safety edge treatments 

to reduce the potential for overcorrection-type crashes. The Governor’s Highways Safety 

Program oversees a variety of important safety campaigns, including "Booze It and Lose It" and 

"Click It or Ticket It."

7. Identify which external partners are involved with Highway Safety Improvement Program planning.

An update of the Strategic Highway Safety Plan (SHSP) for the State of North Carolina 

was launched in 2015. This SHSP (also referenced herein as the Plan) is an important 

component of North Carolina’s Highway Safety Improvement Program (HSIP). The need for a 

SHSP was established by the federal transportation funding legislation, the Safe, Accountable, 

Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), and 

strengthened by the passage of the Moving Ahead for Progress in the 21st Century Act (MAP21) in July 2012. MAP-21 specifies that the SHSP must be developed based on safety data on all 

public roads, be developed in consultation with stakeholders, employ a multidisciplinary 

approach, describe a program of safety strategies, and consider other highway safety plans and 

processes.

This updated SHSP was developed through the collaborative efforts of diverse safety 

stakeholders representing the users of the North Carolina highway system and encompassing 

the 4 E’s of highway safety—education, enforcement, engineering, and emergency services. 

These safety stakeholders include State, regional, local, and tribal agencies, as well as other 

public and private partners. This Plan presents a statewide, comprehensive, and collaborative 

approach for reducing fatalities and serious injuries on North Carolina’s roadways. Serious 

injuries are those obviously serious enough to prevent the injured person from performing his 

or her normal activities for at least one day beyond the day of the crash. These are also called 

Type A injuries.

The North Carolina SHSP was first developed in 2004 by the North Carolina Executive 

Committee for Highway Safety (ECHS) in support of the American Association of State Highway 

and Transportation Officials (AASHTO) Strategic Highway Safety Plan. The ECHS adopted 

AASHTO’s goal to reduce the statewide fatality rate to 1.0 fatalities per 100 million vehicle miles 

traveled (MVMT). The revised plan of 2006 identified 14 emphasis areas. Significant progress 

was made toward the Plan’s overall goal, resulting in a dramatic decrease in the number of 

fatalities per 100 million vehicle miles traveled (MVMT) over the eight-year period from 2006 to 

2013. The 2015 fatality rate is above 1.2 fatalities per 100 MVMT. Nationally, the fatality rate 

has also declined during the same period, although not as sharply as in North Carolina. 

Evaluations of North Carolina’s engineering safety programs have demonstrated that the 

collaborative and focused statewide efforts of the SHSP in recent years have contributed to the 

reductions in fatalities and serious injuries. Many other factors may also have contributed to 

this decline, such as vehicle enhancements and economic influences.

Although the safety stakeholders implementing the Plan have made significant progress in 

achieving the statewide goal since 2006, there is still work to be done. In 2015, 1,386 people 

died on North Carolina’s roadways, and another 2,423 people were seriously injured. 

Additionally, the downward trend in fatalities and serious injuries has flattened over the last 

few years. The update of the original State SHSP—presents refined goals and objectives, new 

safety emphasis areas, and additional strategies and actions to build on past success and to 

continue to reduce fatalities and serious injuries on North Carolina’s roadways. This document 

can be found on the web at http://ncshsp.org/.

The goals of the Plan will be achieved through the implementation of strategies and actions in 

nine safety emphasis areas. These emphasis areas represent the greatest opportunity for the 

safety stakeholders to focus their efforts to achieve the goals of this Plan. The safety 

stakeholders selected these emphasis areas cooperatively through a data-driven approach, 

noting that many individual crashes can be attributed to more than one emphasis area. For 

example, a crash may involve speeding, intersection safety, and occupant protection. 

Therefore, the following nine emphasis areas provide an opportunity to address crashes from 

multiple perspectives.

-Demographic Considerations

-Driving While Impaired

-Emerging Issues and Data

-Intersection Safety

-Keeping Drivers Alert

-Lane Departure

-Occupant Protection/Motorcycles

-Pedestrians and Bicyclists

-Speed

To achieve the Plan’s goals to reduce fatalities and serious injuries by half and to move North 

Carolina closer to Vision Zero, significant reductions are needed in each emphasis area.

In general, the goal for each emphasis area is to reduce fatalities and injuries by half. Some 

emphasis areas present a greater opportunity to reduce fatalities and serious injuries than 

others. Factors such as trends in exposure rates and the availability of effective strategies are 

different for each emphasis area and affect the opportunity to reduce fatalities and serious 

injuries. For example, several lane departure strategies are known to be effective at reducing 

crashes on North Carolina’s roads; their increased implementation presents an opportunity to 

greatly reduce fatalities and serious injuries. Conversely, because motorcycle ridership is 

increasing in North Carolina, crash reductions from effective strategies must outpace the 

growth in crashes that is attributed to the increased ridership (e.g., exposure).

Overall, the strategies in the emphasis areas work collectively toward the Plan goal, with some 

emphasis areas expected to contribute more reductions in fatalities and serious injuries than 

others.

In 2016, Governor Pat McCrory announced that $50 million would be dedicated to improving highway 

safety and reducing the number of traffic accidents throughout North Carolina. Improvements 

supported by the funds included high friction surface treatments, turn lanes, guardrails and traffic 

signals. The $50 million are state funds advanced to the projects that NCDOT will request 

reimbursement payments through the federal HSIP.

In the fall of 2015, FHWA conducted a national HSIP scan tour. The tour team visited North Carolina, 

because the state was identified as a high-performing state. The scan tour report noted several 

noteworthy practices in North Carolina including:

-Documentation of HSIP Processes

-Coordination with Internal and External Partners

-Understanding the Relationship between the SHSP and HSIP

-Making Data-Driven Safety Decisions

-Addressing Local Road Needs

-Considering All "4E's"

-Identifying Opportunites to Streamline Project Delivery

-Evaluating the Success of the Program

systemic programs to implement wide edge lines, enhanced curve warning signs and safety edge 

treatments.

Highway Safety Improvement Program (HSIP) provides a continuous and systematic

transportation network screening process that identifies, analyzes, investigates, diagnoses and

treats specific traffic safety concerns throughout the state. The goal of the federally required

HSIP is to reduce the number of traffic crashes, injuries, and fatalities by reducing the potential

and the severity of public roadway collisions. The collaboration between HSIP Project Group

Analysts and the Regional Traffic Engineers that research, investigate, recommend treatments,

and develop realistic cost effective safety projects has yielded highly effective safety performance even 

during a time of continued growth in North Carolina.

The emphasis of the state-funded Spot Safety and federally-funded Highway Safety

Improvement Programs is to identify and treat high crash and/or high severity locations with

relatively low cost solutions in order to address safety concerns along NC roadways. These

programs are a vital tool in improving safety at intersections and segments of roadway where

safety needs have been identified by citizens, government officials, internal staff, or through one

of NCDOT’s safety initiatives. With these programs, Regional Traffic Engineers collaborate

with designers and project managers on project scope and prioritization in order to develop

realistic, time-sensitive, and cost effective projects that address safety issues.

The projects developed and constructed under these safety programs are inspected upon

completion to ensure the identified safety issues have been mitigated and the project was

constructed according to the plans. Management of this program by the State Traffic Engineer

and his staff provide statewide consistency in treating areas in a systematic, evidence driven and

needs based approach. These vital safety funding program efforts have shown an average return

on investment of 14:1.

The Alternative Analysis Initiative quantifies the safety performance of different transportation

project alternatives selected for study during the National Environmental Policy Act (NEPA)

process. Using Highway Safety Manual (HSM) predictive methodologies, we compare the

expected safety performance of different alternatives based on the specific design elements

associated with each alternative (curve radius, lane widths, shoulder widths, number of

driveways, grades, intersection features, etc.). The predicted crash numbers give some scale of

the number of crashes to expect, but the percentages give a really good comparison regarding the

effects of the specific design elements on each alternative that are expected to have on safety.

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

overcome this in the future.

NCDOT is responsible for the safety of nearly 80,000 miles of rural and urban highways. Cities, towns, 

other state agencies and federal agencies are responsible for over 26,000 miles of streets; most of this 

mileage is downtown and residential streets. While NCDOT administers HSIP funds, most municipalities 

are hesitant to participate due to the federal guidelines, restrictions and limitations on funding. Local 

governments are unwilling to administer the competitive bidding process. The complex federal safety 

program process and lack of flexibility discourages many opportunities to utilize the HSIP for low-cost 

safety projects. In some cases administrative costs may be higher than the project costs. 

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

progress on which you would like to elaborate.

In an attempt to assess the safety of our roads, the Safety Evaluation Group of the Traffic Safety Systems 

Management Section has evaluated hundreds of countermeasure projects and safety treatments. The 

methodologies used in these evaluations offer various philosophies and ideas, in an effort to provide 

objective countermeasure crash reduction results. This information is provided so the benefit or lack of 

benefit for this type of project can be recognized and utilized for future projects. As the Safety 

Evaluation Group completes additional reviews for these types of countermeasures, we will be able to 

provide objective and definite information regarding actual crash reduction factors. These evaluations 

can be found on our website at: https://connect.ncdot.gov/resources/safety/Pages/SafetyEvaluation.aspx.

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

elaborate.

The N.C. Department of Transportation is committed to measuring and improving performance. 

The department's Organizational Performance Dashboard, which is featured on NCDOT's web 

page, serves as an indicator of how well we are meeting our mission and goals. One major 

NCDOT goal is "Making our transportation network safer". This is defined as the total number 

of statewide fatalities on NC roads per 100 million vehicle miles traveled for the calendar year to 

date. The fatality rate gauge shown on our Performance Dashboard is accompanied by a trend 

chart of the total number of fatalities, crashes and injuries by year. The Performance Dashboard 

can be found at https://apps.dot.state.nc.us/dot/dashboard/

Many staff members within NCDOT have a work performance metric for highway safety 

included in their year-end appraisal.

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

Safety Improvement Program?

Other-Other - Decline in Fatal Rates

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

Other-Many supervisors and managers in NCDOT have a performance metric for crash rates listed in 

their year-end appraisal.

Other-NCDOT engineers will review 1000 miles of secondary roadway with stautory speed limits each 

year. Appropriate speed limits will be determined and posted.

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

The use of safety edge is being accepted by highway operations staff as not simply a safety 

enhancement but also a maintenance enhancement. Safety edge will be required on all contract 

resurfacing that is let by the Central and Division offices. NCDOT has initiated a project to study the 

impacts of wide edge markings on two-lane rural roads. 60% of all highway fatalities in North Carolina 

are a result of roadway departure crashes. 

NCDOT has invested in several systemic programs including upgrading guardrail end units, installing long 

life pavement markings for positive guidance, and funding of vulnerable user projects.

SKIP The Safety Evaluation Group (SEG) evaluates projects in an attempt to assess the safety of our

roads in North Carolina. This information is provided so the benefit or lack of benefit for a

particular type of project can be recognized and utilized for future projects. There are currently

over 1,000 project evaluations on the web page from 45 topic areas. For more information on our completed projects, use the 

following link:

https://connect.ncdot.gov/resources/safety/Pages/Safety-Evaluation.aspx

Safety Program Evaluations

A majority of the reports the SEG has completed evaluate the safety aspects of a location-specific spot safety project or a 

hazard elimination project. These are projects that have been

funded to address a particular documented safety issue or potential safety issue. An overall

evaluation of the NCDOT spot safety program with projects completed through 2007 shows a

benefit-cost ratio of 14:1 using 2005 dollars.

Topic Oriented Safety Evaluations

The SEG also conducts large scale studies using data from locations across the State. As we

complete multiple evaluations for a particular type of countermeasure, we are able to provide

objective and definite information regarding actual crash reduction factors. Some of the topic

areas include: All-Way Stops, Roundabouts, Overhead Flashing Beacons, Flashing Yellow Arrow,

Vehicle Entering When Flashing Signs, Flashers in School Zones, Speed Enforcement Programs,

and Paved Shoulders. The methodologies used in the evaluations offer various philosophies and

ideas. When possible and appropriate, we attempt to use statistical analysis to account for

potential study biases. Numerous topic-oriented safety studies completed by the SEG have been published in peer-reviewed 

journals.

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

which you would like to elaborate. 

The North Carolina Highway Safety Improvement Program (HSIP) is an organized and systematic safety

process developed to identify, analyze, investigate and improve potentially hazardous locations with

concentrations and patterns of correctable crashes. The program is able to determine locations that

exceed minimum warranting criteria that are based on multiple factors that, in most cases, include

severity, frequency, and crash type. The program is presently structured into six distinct phases:

I. Development of warranting criteria

II. Identification of potentially hazardous locations meeting minimum warrant criteria

III. Detailed crash analysis of program locations

IV. Engineering field investigation of program locations and evaluation of potential recommendations

(where appropriate)

V. Project development

VI. Implement countermeasures

VII. Evaluation of countermeasures implemented with HSIP funds

The warrants developed by the Traffic Safety Systems Section (TSSS) have consistently shown the ability

to identify intersections, sections, and bicycle/pedestrian intersections with severe injuries and chronic

crash patterns. The Regional Traffic Engineers utilize thorough investigations, traffic operations and

safety expertise and proven tools such as signal warrant studies, sight distance measurements, Crash

Reduction Factors and Benefit to Cost analysis to ensure that effective projects are developed. Projects

are selected through a competitive Benefit to Cost based program. Evaluations completed by the Traffic

Safety Systems Section have shown that the average project yields a 14 to one return.

In an attempt to assess the safety of our roads, the Safety Evaluation Group of the Traffic Safety Systems Management Section has 

evaluated hundreds of projects. The methodologies used in NCDOT's evaluations offer various philosophies and ideas, in an effort to 

provide objective countermeasure crash reduction results. This information is gathered so the benefit or lack of benefit for this type 

of project can be recognized and utilized for future projects. As the Safety Evaluation Group completes additional reviews for various 

types of countermeasures, we will be able to provide objective and definite information regarding actual crash reduction factors.

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.
