Executive Summary

The purpose of the North Carolina Highway Safety 

Improvement Program (HSIP) is to provide a continuous and 

systematic procedure that identifies, investigates and 

addresses specific safety concerns throughout the state. The 

ultimate goal of the HSIP is to reduce the number of traffic 

crashes, injuries, and fatalities by reducing the potential for and 

the severity of these incidents of public roadways. 

North Carolina recognizes traffic crashes as a significant 

problem that continues to challenge the state. In 2013, there 

were over 240,000 reported traffic crashes that resulted in 

1,264 persons killed and over 100,000 injuries on our roadways. 

The socioeconomic impact of these crashes is severe, resulting 

in a loss of over $10.1 billion to the economy of North Carolina 

annually. This impact translates to a crash cost to the state of 

over $1 million every hour and approximately $28 million every 

day and a staggering social impact as well. North Carolina has 

established a vision to have a multi-disciplinary, 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, 
2014 North Carolina Highway Safety Improvement Program

2

there is a coordinated strategic effort to address emerging 

safety issues. In January 2008 the Executive Committee for 

Highway Safety met to reexamine their goals. The committee 

agreed to adopt a 2.5% reduction in annual fatalities each year 

over the next 20 years as the new goal.

This “HSIP Report” describes 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 “RailwayHighway Crossing Report” as a separate report submission. 

North Carolina DOT has opted to use the 2013 Calendar Year as 

the reporting period for the “HSIP Report”; however, some of 

our 2014 plans, goals, 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 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.

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

highways. NCDOT highway network covers nearly 80,000 roadway miles which includes rural roadways 

classified as local; municipal governments maintain some downtown streets, residential streets and 

subdivision roads.

As a future goal, NCDOT is currently working with the UNC Highway Safety Research Center (HSRC) to 

develop a low cost safety improvements training course that will focus on municipalities. NCDOT is 

hopeful that the low cost safety improvements training course will help municipalities gain confidence

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.

Briefly describe coordination with internal partners. 

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

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 and towns 

are responsible for over 21,000 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. Local governments are unwilling to administer the competitive bidding process. The 

complex federal safety program process discourages many opportunities to utilize the HSIP for low-cost 

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

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. 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:

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.

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. The Traffic Safety Systems Section is working with all 14 

highway divisions to systemically treat hundreds of identified curve locations with enhanced warning 

signs.

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 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.
