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 

2019, there were over 310,000 reported traffic crashes that resulted in 1,474 persons killed and over 120,000 

injuries on our roadways. The socioeconomic impact of these crashes is severe, resulting in a loss of over 

$30.5 billion to the economy of North Carolina annually. This impact translates to a crash cost to the state of 

over $3.4 million every hour and approximately $83 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, there 

is a coordinated strategic effort to address emerging safety issues. In 2019, North Carolina updated the 2014 

Strategic Highway Safety Plan (SHSP) in coordination through the NC Executive Committee for Highway 

Safety. The goals established in the 2019 SHSP are to reduce fatalities and serious injuries by half by 2035 

based on 2018 data and move towards zero by 2050. 

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 “Railway-Highway Crossing 

Report” as a separate report submission. North Carolina DOT has opted to use the 2019 Calendar Year as the 

reporting period for the “HSIP Report”; however, some of our 2020 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 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. 

Each year the Transportation Mobility and Safety Division (TMSD) conducts network screening to identify 

potentially hazardous intersections and sections. Crash data and collision diagrams are compiled for the higher 

ranked locations. These tools are then used to conduct a field investigations of these sites. NCDOT staff also 

conduct numerous field investigations resulting from specific fatal sites and concerns from law enforcement, 

municipalities and citizens. Data from the field investigation is used to determine feasible countermeasures. In 

many cases low-cost countermeasures can be funded by highway maintenance programs. Other 

improvements are developed into projects that compete for state and federal highway safety program funds. 

Selection of projects is determined by a statewide data-driven selection process each quarter. The selected 

projects are approved by the NCDOT Board of Transportation. Project designs are developed and contracts 

are advertised. Contracts are awarded and projects are constructed, then final field inspections are conducted 

by division and/or TMSD personnel to make sure that the project is completed according to the approved plans 

and specifications. All significant safety projects are evaluated individually and once enough projects of a 

particular countermeasure have been implemented, the effectiveness of the countermeasure is evaluated. 

Where is HSIP staff located within the State DOT? 

 Operations

NCDOT’s Traffic Safety Unit has approximately 40 positions dedicated to improving safety and mobility. There 

are also Traffic Engineering staff in the 14 Highway Divisions who are charged with maintaining and improving 

our transportation network. 

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process 

The HSIP program is funded with 90% federal funds and 10% matching state funds. Competing HSIP 

candidate projects are submitted and reviewed quarterly by an interdisciplinary Safety Project review team that 

recommends approval of federally funded safety projects. These projects are prioritized for funding according 

to a safety benefit-to-cost (B/C) ratio, with the safety benefit being based on crash and injury reductions. Once 

programmed HSIP (W-Projects) become part of NCDOT’s State Transportation Improvement Program (STIP). 

NCDOT has also funded systemic Vulnerable User, Pedestrian and Bicycle, and Signal System projects. 
2020 North Carolina Highway Safety Improvement Program

Page 6 of 54

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

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 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. 

We are not aware of any crashes on tribal roads and are not certain if they are required to report crashes. We 

will make a concerted effort to reach out to tribes to determine the number and severity of crashes on their 

roadways, as well as identify potentially hazardous locations. 

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

Bureaus, Divisions) are involved with HSIP planning. 

• Design 

• Governors Highway Safety Office 

• Operations 

• Planning 

• Traffic Engineering/Safety 

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 Strategic 

Prioritization 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. Many resurfacing projects 

are utilizing safety edge treatments to reduce the potential for over-correction 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.". The NCDOT Rail Division and GHSP participate on our safety project selection 

committee. The Transportation Mobility and Safety Division, GHSP, and the State Highway Patrol (external 

partner) have developed a collaborative program to identify and improve rural highway corridors that have high 

fatal and serious injury rates. 

Identify which external partners are involved with HSIP planning. 

• Local Government Agency 

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

• Other-NC State Highway Patrol 
2020 North Carolina Highway Safety Improvement Program

Page 7 of 54

Describe coordination with external partners. 

Planning Organizations utilize traffic safety data to develop and prioritize transportation plans. Members of the 

NC State Highway Patrol and local government transportation agencies also regularly participate in NCDOT's 

Road Safety Audit Program. The NC Transportation Secretary chairs the NC Executive Committee for Highway 

Safety and partner agency representatives are actively involved in the committee. The partner agency 

representatives currently includes members from the following: NC Conference of District Attorneys, UNC 

Highway Safety Research Center, City of Greensboro, NC Association of MPOs, FMCSA, NCSHP, Students 

Against Destructive Decisions (SADD), FHWA, NC Department of Health and Human Services, AARP, AAA 

Carolinas, NC Department of Insurance and Eastern Carolina Injury Prevention Program. 

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

elaborate. 

The North Carolina Strategic Highway Safety Plan (SHSP) (herein referred to as the Plan) is essential to 

addressing highway safety in our State. The Plan is a key component of North Carolina’s Highway Safety 

Improvement Program, a core-Federal-aid program directed at reducing fatalities and serious injuries on all 

public roads. North Carolina’s Executive Committee for Highway Safety first developed the SHSP in 2004. 

Updates in 2006 and 2014 were implementation focused, identifying significant contributing factors in crashes 

and implementation strategies with the most potential to address those crashes. Information about the previous 

Plan, developed in 2014, can be found here . In 2015, the Federally funded legislation Fixing America’s 

Surface Transportation Act continued the requirements that States develop an SHSP that is data- and 

multidisciplinary stakeholder-driven and that analyzes highway safety concerns and identifies opportunities to 

improve safety on all public roads. The 2019 Plan is an update to the 2014 Plan and the fourth iteration of the 

Plan since 2004, and the first 5-year update under recent Federal regulations. 

The North Carolina Department of Transportation updated the SHSP in 2019 through the collaborative efforts 

of diverse safety stakeholders representing the users of State’s 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.

The Plan is organized by Focus Areas, which group Emphasis Areas addressing similar crash types, road 

users, or other characteristics. This framework supports the importance of overlaps and provides a roadmap 

for implementation. Safety partners representing the Emphasis Areas will work together under the umbrella of 

the Focus Area to prioritize and implement the actions in each Emphasis Area Action Plan. The following 

briefly introduces the Focus Areas and corresponding Emphasis Areas. 

• Roadway Infrastructure 

o Intersections 

o Lane Departure 

• Human Behavior 

o Alertness 

o Occupant Protection 

o Substance Impaired Driving 

o Speed 

• All Users 

o Younger Drivers 

o Older Drivers 

o Motorcyclists 

o Pedestrians, Bicyclists, and Personal Mobility 

• Data and Evaluation 
2020 North Carolina Highway Safety Improvement Program

Page 8 of 54

o Emerging Issues and Data 

• Safety Culture 

o All Emphasis Areas 

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. 

Program Methodology 

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

implementation and evaluation processes?

No

The Traffic Safety Systems Section has begun developing an HSIP manual that will detail the multi-step HSIP 

process by the end of 2020. 

The North Carolina DOT maintains several HSIP documents and information on 

https://connect.ncdot.gov/resources/safety/Pages/NC-Highway-Safety-Program-andProjects.aspx. This 

includes mapped HSIP locations from 2015-2019, HSIP Potentially Hazardous Location Detailed Reports by 

county, intersection reports, bike/pedestrian reports, the active spot safety project list, all safety project 

evaluations and the NCDOT Crash Reduction Factor list. 

NCDOT also conducted an HSIP assessment in 2017.

investigated each year. The Traffic Safety Unit from central headquarters also conducts approximately 8 Road 
2020 North Carolina Highway Safety Improvement Program

Page 13 of 54

Safety Audits annually utilizing independent, multi-disciplinary teams (currently, the RSR Program has been 

paused due to COVID-19 safety measures). Also NCDOT staff conduct numerous field investigations resulting 

from concerns of law enforcement, local government officials and citizens. NCDOT traffic engineers can also 

uncover safety issues during their study of traffic operations. Data from the numerous field investigations is 

used to determine feasible safety countermeasures.

Does the State HSIP consider connected vehicles and ITS technologies? 

No

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.

NCDOT's Roadway Safety Management Process uses many HSM techniques for diagnosis, countermeasure 

selection, economic appraisal, project prioritization and safety evaluations. TSU's Alternative Analysis Initiative 

utilizes Highway Safety Manual (HSM) predictive methodologies to compare the expected safety performance 

of different project alternatives based on specific roadway design elements.

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

elaborate.

NCDOT is continuing to develop safety performance functions and will utilize the Interactive Highway Safety 

Design Model (IHSDM) application on future STIP projects. NCDOT is actively working on new 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 
2020 North Carolina Highway Safety Improvement Program

Page 14 of 54

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.

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

Describe any other aspects of the State’s progress in implementing HSIP projects on 

which the State would like to elaborate. 

NCDOT is utilizing and evaluating a variety of methods to improve project delivery times and reduce the overall 

cost of delivering HSIP projects. This includes combining multiple safety improvements in a single contract, the 

use of design-build delivery mechanisms for fast-track project delivery with well-defined scope, and the use of 

on-call contractors to facilitate immediate delivery of identified projects.

Provide additional discussion related to general highway safety trends.

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 yearend appraisal.

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

For the 2021 Highway Safety Improvement Plan (HSIP), the goal is to reduce total fatalities by 4.20 percent 

each year from 1,427.2 (2015-2019 average) to 1,309.9 (2017-2021 average) by December 31, 2021.

Number of Serious Injuries:3656.1

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

For the 2021 Highway Safety Improvement Plan (HSIP), the goal is to reduce total serious injuries by 3.24 

percent each year from 3,905.0 (2015-2019 average) to 3,656.1 (2017-2021 average) by December 31, 2021.

Fatality Rate:1.105

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

For the 2021 Highway Safety Improvement Plan (HSIP), the goal is to reduce the fatality rate by 4.35 percent 

each year from 1.208 (2015-2019 average) to 1.105 (2017-2021 average) by December 31, 2021.

Serious Injury Rate:3.065

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

For the 2020 Highway Safety Improvement Plan (HSIP), the goal is to reduce the serious injury rate by 3.35 

percent each year from 3.281 (2015-2019 average) to 3.065 (2017-2021 average) by December 31, 2021.

Total Number of Non-Motorized Fatalities and Serious Injuries:504.4

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

For the 2021 Highway Safety Improvement Plan (HSIP), the goal is to reduce the total non-motorized fatalities 

and serious injuries by 3.65 percent each year from 543.4 (2015-2019 average) to 504.4 (2017-2021 average) 

by December 31, 2021.

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

safety performance targets. 

Through collaboration with the Governor's Highway Safety Program (GHSP), Metropolitan Planning 

Organizations (MPOs) and the Executive Committee for Highway Safety (ECHS), we continue to work together 

to establish targets for the five safety performance measures. Initially, the safety performance targets were 

discussed, and a direction was set through our ECHS in September 2016. The ECHS includes partners from 

top level agency and department heads from various state and local agencies, including the GHSP. These 

safety champions are key policy and business funding decision makers in the highway safety arena. The 

direction set by the ECHS follows the goals set through our 2014 State Highway Safety Plan (SHSP) 

concerning the reduction of fatalities and serious injuries. Historically, the numbers and rates for the five safety 

performance measures/targets were annually gathered and adjusted in accordance with the 2014 SHSP goal 

of a 50% reduction of fatalities and serious injuries by the year 2030. NCDOT continually provides target 
2020 North Carolina Highway Safety Improvement Program

Page 40 of 54

setting crash data to each of the MPOs so they could establish their 2018, 2019 and upcoming 2020 safety 

performance targets. Our state has completed our 2019 SHSP update and the goal has been adjusted in 

hopes of providing a better opportunity for our state to make significant progress towards meeting our future 

safety performance targets. The goals established in the 2019 SHSP are to reduce fatalities and serious 

injuries by half by 2035 based on 2018 data and move towards zero by 2050.

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2019 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 1214.7 1430.4

Number of Serious Injuries 2490.6 4078.4

Fatality Rate 1.097 1.210

Serious Injury Rate 2.228 3.276

Non-Motorized Fatalities and 

Serious Injuries

403.7 515.0

Based on our data as of 6/25/2020, our state was determined to have not met or made significant progress 

toward the CY 2020 targets. In order to align with the goals of the 2014 North Carolina Strategic Highway 

Safety Plan (SHSP), our state’s Executive Committee for Highway Safety (ECHS) agreed to set our safety 

targets for each of the five safety performance measures so that they will support the reduction of our 

statewide fatalities and serious injuries by half before 2030. Because the safety targets are set based on the 

aspirational 2014 SHSP goal, it will be difficult to make significant progress towards meeting the fatalities, 

fatality rate, and non-motorized fatalities and serious injuries safety performance targets based on the currently 

increasing trends in our statewide fatalities and serious injuries. Additionally, due to the substantial increases in 

historical serious injury trends in September 2016 caused by the national definition change for “Suspected 

Serious Injury (A)”, it will also be difficult to make significant progress towards meeting the serious injuries and 

serious injury rate safety performance targets.

Applicability of Special Rules

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

No

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio 

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

the State's program level evaluations. 

NCDOT has a robust project evaluation program. Every project that is funded through the federal HSIP dollars 

and the NC spot safety dollars are evaluated from a before and after perspective. These evaluations include 

project background, before and after summary data tables, and before and after collision diagrams. The main 

objective of these evaluations is to provide feedback to our field personnel as to whether the project was 

successful. The main thing measured is if the pattern of crashes the safety countermeasure was installed for 

actually reduced in the after period. 

NCDOT also looks at all projects that are completed over a period of time and assesses how many crashes 

were reduced, with a crash cost attached to those crashes, versus the original project costs. Upon reviewing 

approximately 600 projects, the benefits of crashes reduced resulted in a 14:1 benefit cost. Our field personnel 

also have an annual expectation for developing safety projects and getting those projects on the ground. 

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

success of the Highway Safety Improvement Program? 

• # RSAs completed 

• Increased awareness of safety and data-driven process 

• Increased focus on local road safety 

• More systemic programs 

• Policy change 

• Other-Reduction in Target Crashes

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. Completed project evaluations can be 

found at the link below: https://connect.ncdot.gov/resources/safety/Pages/Safety-Evaluation.aspx 

Describe any other aspects of HSIP effectiveness on which the State 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: 

• Development of warranting criteria and Identification of potentially hazardous locations meeting minimum warrant criteria 

• Detailed crash analysis of program locations 

• Engineering field investigation of program locations and evaluation of potential recommendations (where appropriate) 

• Project development 

• Implement countermeasures 

• 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.

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. 

There are approximately 107,000 miles of public roads in the State of North Carolina. Of those, the NCDOT maintains approximately 80,000, which equates to approximately 75% of all public roadways in the State. It is important to note 

that for the purposes of this plan, when referencing State and Non-State in terms of what the State collects it refers to ownership/maintenance; when referencing Non-Local and Local in terms of the MIRE FDE, it refers to functional class. 

The Operations Program Management Unit is responsible for collecting and maintaining the roadway inventory, and the GIS unit is responsible for the line work. ESRI Roads and Highways is used to maintain the LRS and many roadway 

inventory elements. A roadway characteristics file is published every quarter. Anyone can access the roadway inventory GIS files; they are available on the Connect NCDOT website, (https://connect.ncdot.gov/resources/gis/Pages/GISData-Layers.aspx).

The Division of Highways has the authority/responsibility for determining the improvements needed to achieve compliance with the MIRE FDE requirements. These decisions are made jointly between Safety, GIS, and the Operations 

Program Management Unit, with safety driving the need for new elements. 

NCDOT completed a gap assessment in January 2017 comparing their roadway inventory to the FDE listing. The gap assessments results are summarized in this section. 

Non-Local Paved Roads 
2020 North Carolina Highway Safety Improvement Program

Page 51 of 54

Segments

NCDOT collects and maintains all of the segment elements on all State-owned Non-Local Paved roads. NCDOT collects and maintains almost all of the segment elements on all Non-State owned, Non-Local Paved roads. The exceptions 

are Surface Type, Median Type, Access Control, One/Two Way Operations, and Type of Governmental Ownership.

Intersections

The largest gaps in the FDEs for NCDOT are for Intersection data elements. NCDOT does not currently have the majority of the intersection FDEs on Non-Local Paved roads. 

Interchange/Ramp

Of the 11 Interchange/Ramp elements on non-local paved roads, NCDOT maintains 7 on both State and Non-State roads. The 4 missing elements are Interchange Identifier, Location Identifier for Beginning Ramp Terminal, Roadway 

Type at Beginning Ramp Terminal, and Interchange Type.

Local Paved Roads

Of the nine (9) FDEs on Local Paved Roads, all but one (1) (AADT) are collected on all State Roads; and all but 4 (Surface Type, Number of Through Lanes, AADT, and Type of Governmental Ownership) are collected on all Non-State 

roads. 

Unpaved Roads 

NCDOT intends to opt out of collecting FDEs on unpaved roads. NCDOT understands: no HSIP funds can be spent on these roadways; they must consult with affected Indian tribes; and they must notify their FHWA Division Office via 

letter to the Division Administrator.

Appropriate Data Collection Methodology

For the MIRE FDE currently collected, the elements are updated as new roads are added. The GIS group updates the line work annually based on snapshots provided by the Counties. 

There are business edits and data checks built into the system to help ensure the quality of the data, however there are no additional formal QA/QC processes. NCDOT is looking into developing performance measures to help formalize 

their quality practices.

There are two current pilot projects underway to help NCDOT fill the two biggest data gaps – Intersection elements and AADT. NCDOT conducted a pilot to collect data at 3,000 intersections, with the goal of developing a framework for a 

larger scale data collection effort. With regard to AADT, NCDOT has contracted with the University of North Carolina Charlotte on a research effort to develop a process for developing AADT on all public roads. The project is scheduled 

for completion in calendar year 2020. 

NCDOT is currently working on an interchange inventory that will satisfy MIRE requirements for interchanges. It is anticipated that this work will be completed within calendar year 2020. NCDOT has also begun work on developing an 

intersection inventory. It is anticipated that the identification of intersections will be complete within calendar year 2020. Once the identification is complete, the work to begin attributing the intersections will begin.

NCDOT also became a member of the Applications of Enterprise GIS for Transportation, Guidance for a National Transportation Framework (AEGIST) pooled fund study in 2020. This pooled fund study will develop standards for a 

national transportation dataset as well as document best practices for linear referencing systems to maximize data quality and interoperability. One of the initial focuses of the group will be to evaluate preferred methods for managing 

intersection data in a linear referencing system. MIRE accommodations are a large part of this effort.

Coordination with Other Agencies

The largest data gaps exist on Non-State roads. NCDOT plans to analyze the mileage and ownership for the roadways with missing FDEs. Once that effort is complete, NCDOT can determine where there are the largest data gaps and 

what outreach mechanism might be most effective to working with those local agencies. This will help NCDOT determine if they can utilize information already being collected by local agencies, or if a State sponsored data collection effort 

is needed to obtain the data on these roadways. 

Prioritization Criteria for Collection MIRE FDE on All Public Roads

The FDE collection priorities are as follows:
2020 North Carolina Highway Safety Improvement Program

Page 52 of 54

• Short-term: Interchange elements and Non-Local Paved Roads Segment elements, as well as AADT on all public roads. 

• Mid-term: Intersection elements, and any other remaining Non-Local paved road elements. 

• Long-term: Remaining needed Local Paved Roads elements. 

The data will be collected using a variety of tools including deriving elements from existing data, collecting from video logs, utilizing current pavement collection efforts to determine what else might be able to be collected at the same time, 

and utilizing data already being collected from local agencies. This includes exploring what additional information might be collected when the annual linework is collected from the Counties and what additional mechanisms might need to 

be put in place to be able to obtain these data. NCDOT is also exploring if the E911 effort might be able to be utilized to obtain additional data. NCDOT will also explore utilizing the available FHWA technical assistance programs, primarily 

the Roadway Data Extraction Technical Assistance Program (RDETAP), to help fill in data gaps. 

The Safety Group will be responsible for the data collection effort, with support from the Operations Program Management Unit. The data will be integrated into the existing GIS system and be made available through the same portal as 

other roadway inventory data. The update cycle will vary based on element. 

Costs and Resources for Data Collection 

NCDOT has not yet developed any cost estimates, but recognizes that this is one of the next steps needed to be conducted. NCDOT will review the FHWAMIRE Fundamental Data Elements Cost-Benefit Estimation report as a starting 

point, 

https://safety.fhwa.dot.gov/rsdp/downloads/fhwasa16035_051916v10.pdf . 

As mentioned above, NCDOT will also explore utilizing the available FHWA technical assistance programs, namely the RDETAP, to help fill in data gaps, as well as utilizing available TRCC funds for data collection efforts.
