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 

2017, there were over 300,000 reported traffic crashes that resulted in 1,400 persons killed and over 120,000 

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

$26.8 billion to the economy of North Carolina annually. This impact translates to a crash cost to the state of 

over $3.0 million every hour and approximately $73 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. The Executive Committee for Highway 

Safety established a goal to cut the fatalities and serious injuries in North Carolina in half based on the 2013 

figures, reducing the total annual fatalities to 630 fatalities and the total serious injuries to 1,055 serious injuries 

before 2030.

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 2017 Calendar Year as the 

reporting period for the “HSIP Report”; however, some of our 2018 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.

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.

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 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.

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.

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.

Yes

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

An update of the Strategic Highway Safety Plan (SHSP) for the State of North Carolina was launched in 2014.

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 (SAFETEALU), and strengthened by the passage of the Moving Ahead for Progress in the 21st Century Act (MAP-21) in 
2018 North Carolina Highway Safety Improvement Program 

Page 8 of 60

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 (suspected serious 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 2017 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 2017, 1,400 people died on North Carolina’s 

roadways, and another 4,602 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.

1. Demographic Considerations

2. Driving While Impaired

3. Emerging Issues and Data

4. Intersection Safety

5. Keeping Drivers Alert

6. Lane Departure

7. Occupant Protection/Motorcycles
2018 North Carolina Highway Safety Improvement Program 

Page 9 of 60

8. Pedestrians and Bicyclists

9. 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, North Carolina dedicated $50 million 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:

I-Documentation of HSIP Processes

II-Coordination with Internal and External Partners

III-Understanding the Relationship between the SHSP and HSIP

IV-Making Data-Driven Safety Decisions

V -Addressing Local Road Needs

VI -Considering All "4E's"

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 

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.

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.

Does the State want to elaborate on any other aspects of it’s progress in implementing HSIP projects?

Yes

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.

The 2017 North Carolina traffic volume by functional classification was not available by August 22. Thus it was 

assumed that the traffic volumes across all classifications increased by the same rate from 2016 to 2017.

The revised national definition for Suspected Serious Injury crashes (Type A) has caused a significant increase 

in the number of North Carolina crashes reported as Serious Injury.

Are there any other aspects of the general highway safety trends on which the State would like to 

elaborate?

Yes 

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 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. In addition, we had a Safety Target Setting 

Coordination Training Workshop in March 2017 with the MPO’s where FHWA and NHTSA staff covered 

FHWA’s Safety Performance Management Measures and NHTSA’s Safety Performance Measure 

requirements and provided participants with an understanding of Federal safety performance requirements for 

carrying out the Highway Safety Improvement Program (HSIP) and the Highway Safety Plan (HSP). During this 

workshop, the state presented their methodology to the MPO’s and discussed a coordination and collaboration 

process between the State DOT (HSIP and HSP) and MPO’s. The numbers and rates for the five safety 

performance measures/targets are annually gathered and adjusted in accordance with the SHSP goal of a 

50% reduction of fatalities and serious injuries by the year 2030. NCDOT continually provides target setting 

crash data to each of the MPOs so they could establish their 2018 and 2019 safety performance targets.

Evaluation

Program Effectiveness

How does the State measure effectiveness of the HSIP?

Benefit/Cost Ratio

Enter additional comments here to clarify your response for this question or add supporting information.

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 evaluations help determine if the targeted crash pattern decreased after the safety 

countermeasures were installed.

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?

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.
2018 North Carolina Highway Safety Improvement Program 

Page 48 of 60

NCDOT conducted four RSAs in 2017. The NCDOT Road Safety Audit (RSA) Program is designed and 

managed to reduce crashes and injuries by generating safety projects/actions, assist field staff in addressing 

persistent safety problem areas, and improve collaboration amongst stakeholders. NCDOT conducts RSAs in 

an effort to support HSIP project origination and project development. NCDOT RSAs are conducted with 

Department-wide support to ensure perspectives of trained personnel who understand NCDOT policy and 

procedures. Local stakeholders can bring RSA requests forward for both State-maintained and non-State 

maintained roadways and NCDOT will assist in either case. NCDOT conducts RSAs on corridors with multiple 

HSIP locations, and they also query the Field Engineers and Field Division staff for locations where RSAs 

could lead to potential HSIP projects. Staff from regions throughout the State participate in the RSAs in other 

regions, ensuring an outside perspective is obtained in the RSA process.

Safety benefits is now part of the Stragetic Mobility Formula. The Strategic Transportation Investment (STI) 

established the Strategic Mobility Formula, which allocates available revenues based on data-driven scoring 

and local input. The STI is used to develop NCDOT's State Transportation Improvement Program, which 

identifies the transportation projects that will receive funding during a specified 10-year period.

Are there any significant programmatic changes that have occurred since the last reporting period?

The NCDOT Safety Evaluation Group (SEG) 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 recent 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 countermeasure-oriented 

safety studies completed by SEG have been published in peer-reviewed journals.

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

Are there any other aspects of the overall HSIP effectiveness on which the State would like to elaborate?

Yes

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:

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

2. Detailed crash analysis of program locations 

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

4. Project development 

5. Implement countermeasures 

6. 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.

For (79) and (80), these fields are not explicitly stored but can be derived.

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 106,500 miles of public roads in the State of North Carolina. Of those, the NCDOT maintains approximately 79,600, which equates to approximately 75% of all public roadways in the State, ( 

https://connect.ncdot.gov/resources/State-Mapping/Documents/OfficialStateMileage.pdf ). 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 Transportation Asset Analysis Group 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 publish the characteristics file. Anyone 

can access the roadway inventory GIS files; they are available on the Connect NCDOT website, ( https://connect.ncdot.gov/ ). 

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 Transportation 

Asset Analysis Group, 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 

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. 
2018 North Carolina Highway Safety Improvement Program 

Page 57 of 60

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 two (2) (Number of Through Lanes, 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.

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. In 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 set to begin in 

August 2018 and be completed within two years.

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.

The FDE collection priorities are as follows:

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

• Mid-term: Non-Local Paved Road Interchange 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 Transportation Asset Analysis Group. 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. 

NCDOT has not yet developed cost estimates but recognizes this is one of the next steps needed to be conducted. NCDOT will review the FHWA MIRE 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.
