This service provides a quarterly snapshot of the North Carolina state-maintained road network centerlines. Here, the route network is divided into three layers with symbolized Route Classifications listed below.State Maintained RoadsInterstateUS RouteNC RouteSecondary RouteRampsRest AreasOther State Agency RouteState Maintained Roads - Primary RoadsInterstateUS RouteNC RouteState Maintained Roads - InterstatesInterstateNorth Carolina’s route network is comprised of Interstate, US, NC, Secondary Roads, Ramps, and non-state maintained and projected roads required for federal reporting purposes. Route attributes include Route Class, Route Qualifier, Route Inventory, Route Number, Route Name, and County name. The Route ID attribute is an 11-digit composite route number, the identifier for the Dominant Route. It uniquely identifies routes statewide and should be used as the route identifier when performing LRS analysis using route/milepost referencing.NCDOT adopted the road centerline based Linear Reference System (LRS) Network as it’s official Enterprise LRS, to which multiple road inventory attributes are referenced along measured routes throughout North Carolina. These routes are classified as either System or Non-System routes. System routes are routes within the state-maintained road network, and are comprised of Interstates, US Routes, NC Routes, Secondary Routes, Ramps, and Non-System Routes. Non-System routes are routes that are typically not maintained by NCDOT, but instead by a local agency (county, city or MPO/RPO). The local agency is the source for updating these Non-System routes in NCDOT’s LRS. The collection of routes, System and Non-System, is the NCDOT LRS Network referred to as MilePoint.MetadataThe metadata for the contained layers of the NCDOT State Maintained Roads service is available through the following links:NCDOT Route ArcsPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the State Maintained Roads data.

This service provides lines representing posted speed limits along centerlines of North Carolina state-maintained roads. This data comes from traffic ordinances governing speed limit; where there is no ordinance, the speed limit is 35 within municipalities and 55 outside. The N.C. Department of Transportation sets the speed limit for all state-maintained roads, including access-controlled highways, which are highways with medians that require drivers to enter or exit only at interchanges with bridges, inside the town or city limits. For other state-maintained roads within the municipal limits, NCDOT and the town or city must concur before changing the speed limit. Roads are designed for a specific speed. NCDOT may review the speed limit for various reasons, such as part of a study to improve highway safety, or for proposed new developments. Citizens and local officials may also request NCDOT to conduct a speed zone study to determine whether a road has the appropriate speed limits and signage.The department considers several factors when adjusting the speed limit, such as:Alignment of the roadwayTypes of development along the roadwayThe density, or number, of driveways on a corridorHow far one can see the roadCrash historyVarious speed dataOne of the most common types of speed data NCDOT uses is based on the speed at or below which 85 percent of drivers are traveling. NCDOT uses the 85th percentile to help avoid posting speed limits that are artificially low, which can become difficult to enforce. In the absence of strict enforcement, most people drive at the speed they are comfortable with, regardless of the speed limit.MetadataThe metadata for the contained layer of the NCDOT Speed Limit Service is available through the following link:Speed LimitPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the Speed Limit data.

An arc layer for visual representation of the state road system where each arc/record is split at each state maintained road intersection. This is a digital file of the North Carolina Department of Transportation's Linear Referencing System that represents the routes and attributes of the NCDOT state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes and Ramps. This layer also includes some non-state maintained and projected roads that are required for reporting purposes. This layer also contains some additional routes to meet the Federal Highway Administration's (FHWA) data requirements for the Highway Performance Monitoring System (HPMS). HPMS is a national level highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the Nation's highways. States are required to submit an HPMS report to FHWA annually. The additional routes include: Projected Routes - generalized locations of projected routes that will become part of the National Highway System (NHS) when they are built. Non-state maintained roads - generalized locations of roads that are owned by local, state and federal entities. Only non-state maintained roads that are eligible for federal aid are included. Currently there is no connectivity enforced between the state-maintained roads and the non-state maintained roads. Data quality is tracked using the revision document fields (REVDOC_TYP_CD and REVDOC_NUM). Legacy data are coded as not verified. These data are updated on an ongoing basis to improve data quality and the revision document fields are updated accordingly. As new data are added the geometry and spatial location are verified with the most current information available.

This service provides lines representing statewide road centerlines on publicly accessible roads segmented by a subset of road characteristics for the state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps. Each arc/record is split where road characteristics change along a route. This data supports the Federal Highway Administration's (FHWA) data requirements for the Highway Performance Monitoring System (HPMS). HPMS is a national level highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the nation's highways. States are required to submit an HPMS report to FHWA annually. This data also contains projected routes, generalized locations of routes that will become part of the National Highway System (NHS) when they are built. The non-system roads are consumed and conflated from authoritative sources, including local (i.e., county), state (i.e., parks) and federal (i.e., Forest Service) entities.This data is updated quarterly, usually February, May, August, and November.MetadataThe metadata for the contained layer of the NCDOT Road Characteristics Service is available through the following link:Public Road CharacteristicsPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the Road Characteristics data.

These data depict Road Segment Centerlines and attributes for roads that are managed and maintained by the National Park Service. Road data are used for many purposes including planning and management, mapping and condition assessment, routing and navigation, public information, emergency response, and research. A current, accurate representation of park roads is needed for national reporting and a variety of mapping requirements at all levels of the National Park Service and the general public. A National-level dataset allows the NPS to communicate a consistent and high-quality roads database to NPS staff, partners, visitors, and entities that produce maps and location-based services of park units. The collection, storage, and management of road-related data are important components of everyday business activities in many Federal and State land-managing agencies, road organizations, and businesses. From a management perspective, road data must often mesh closely with other types of infrastructure, resource, and facility enterprise data. For the public using paper maps, the internet, GPS or other instrumentation, standard data formats enable users to consistently and predictably identify specific trails and a core set of corresponding information. Today, digital road data are a necessity throughout a road data management life-cycle, from road planning through design, construction, operation, and maintenance. Automating, sharing, and leveraging road data through this widely accepted standard can provide a variety of important benefits: Efficiency – creating and gathering road data that are standardized and readily usable. Compatibility – compiling data from one project or discipline that can be compatible with other applications; Consistency – using the same standards, meshing data produced by one organization with that developed by another; Speed – hastening the availability of data through a reduction in duplicative efforts and lowered production costs (Applications can be developed more quickly and with more interoperability by using existing standards-compliant data); Conflict resolution – resolving conflicting road data more easily if compliant to the same standards; Reliability – improving the quality of shared road data by increasing the number of individuals who find and correct errors; and Reusability – allow maximum reuse across agencies and support objectives of EGovernment (E-Gov) initiatives and enterprise architecture.

Used to identify city and state maintained streets within the City of Charlotte. Annually, the State Street-Aid Program (Powell Bill) allocates monies to incorporated municipalities who maintains their own streets (GS 136-41.1 thru 136-41.3). Funding for this program comes from a 1-3/4 cent tax per gallon of motor fuel. The amount distributed to each municipality is a factor of population and mileage of publicly maintained streets. Allocations are usually disbursed on or before October 1. Powell Bill funds shall be expended only for the purposes of maintaining, repairing, constructing, reconstructing or widening of local streets that are the responsibility of the municipality.

The STIP is a multi-year capital improvement document which denotes the scheduling and funding of construction projects across the state over a minimum 4 year time period as required by Federal law. North Carolina’s STIP covers a 10 year period, with the first six years referred to as the delivery STIP and the latter four years as the developmental STIP. Per 23 CFR 450.216 & 23 U.S. Code § 135 STIP’s must also:Be submitted to Federal Highway Administration (FHWA) & Federal Transit Administration (FTA) for approval at least every 4 yearsBe fiscally constrained by yearInclude all capital and non-capital projects using Title 23 USC or Title 49 USC funds, other than certain safety, planning, and research fundsInclude metropolitan TIPs (Transportation Improvement Projects) from Metropolitan Planning OrganizationsProvide public comment opportunity on STIP documentAnd include the following information:Project description and terminiEstimated total cost (NCDOT includes Utility, R/W, and Construction costs)Federal funds to be obligatedResponsible agency (such as municipality)The STIP contains funding information and schedules for transportation modes and programs including: Highways, Aviation, Bicycle and Pedestrian, Ferry, Public Transportation, Rail, Governor’s Highway Safety and statewide related programs.The transportation program in the STIP is organized by the 14 transportation divisions. Each Division section includes a funding source reference table and is divided between highway and non-highway project schedules. Projects are also listed by county within each division. This results in some duplication since transportation projects frequently extend across county and division lines. When this duplication occurs, a project is listed in each county in which it is found.Projects are further subdivided by category: interstate, rural, urban, bridge, municipal bridge, bicycle and pedestrian, congestion mitigation, highway safety improvement program, ferry, passenger rail, and roadside environmental. Interstate, rural, urban, bridge, and ferry projects are described by route number. Municipal bridge, bike and pedestrian projects are listed by city or county. Congestion mitigation and passenger rail projects are listed alphabetically by city or county. Highway safety improvement program projects may be listed by route, city, or county. The Public Transportation program list projects first by the transportation partners and providers then by identification numbers.Projects are also listed by the STI category they are funded from, i.e., by Statewide Mobility, Regional Impact, or Division Needs. The phases of projects (such as Right of Way (R), Utility relocation (U), and Construction (C) are listed by Fiscal Year along with their costs and anticipated funding sources.All projects require extensive planning, environmental impact and design studies. The location and exact type of improvements are subject to refinement and modification during the planning and design phases.North Carolina’s STIP is updated every two years and developed in concert with federal and state revenue forecasts, North Carolina Department of Transportation’s (NCDOT’s) Strategic Prioritization process, preconstruction and project development timetables, and in adherence with federal and state laws. North Carolina state law requires Board of Transportation (BOT) action to approve the STIP.For complete information: https://connect.ncdot.gov/projects/planning/STIPDocuments1/NCDOT%20Current%20STIP.pdf

From 2019, the method of testing and assessing the condition of the roads of the unlicensed national road network, also known as the “iQRndemarch”, has evolved to take into account the latest technological and methodological developments. The new version of the iQRn based on innovative technologies and methodologies represents a drastic change in road condition assessment methods and makes it difficult to compare the new data obtained with those obtained under the old evaluation method.

The new iQRn approach makes it possible, specifically concerning the consistency of the roadway, from a lidar survey of the pavement surface, software tools for automatic degradation detection and classification algorithms, to calculate new indicators and to define new classes of pavement condition: — BE = pavement in good condition, not requiring work or requiring ad hoc maintenance work — MS = average pavement, requiring generalised surface maintenance work — Me = pavement in poor condition, requiring structural maintenance work. — Nd = roadway in which the condition has not been determined.

This new classification was applied to sections of roads with homogeneous geometric characteristics and a maximum length of 5 km. For each section, the percentage of area corresponding to each state class shall also be specified.

Each section of the route is defined by: — the name of the road; — its length (in metres); — its beginning (D) and end (F) coordinates expressed in Lambert93 (X, Y, z=0) coordinates or a road tracking system consisting of 4 attributes: — PR = Road Marking Point — dePPR = department where the PR is located — concessionPr = indicates whether the PR is on a conceded section (C) or not (N) — ABS = absciss or distance (in metres) separating the point of the PR to which it relates — rating = specifies whether the section is located on a separate right (D) or left (G) or single pavement road (I) — year = year of measurement of road condition — Theoretical surface, calculated from the length of the section, its number of track and a width of 3,5 metres per track.
