This data set is a linear representation of the extents and attribution associated with speed limit as derived from speed zone records as originally created by the Traffic Engineering Division (TED) of VDOT. This data layer was created for Speed Zone application of Roadway Network System by extracting the zone location information for each feature from the speed zone database and then applying this location description to the linear referencing system built for the Virginia roadway network, and then associating the zone business data to the spatially located feature. Over time new speed zones are created that may overlap - supersede an existing zone. This layer uses business rules to calculate the speed limit. A conventional zone and a variable limit may exist at a single selected location. This data set is maintained by RNS application. There are two types of SPZ records first are for "Statutory" zones where signs are erected to mark roads on which the statutory speed limits apply. The second type of zone is "Resolution" in which the VDOT Commissioner approves changes in speed limits based on recommendations from TED following traffic studies at the proposed location. In these cases the speed limit may be set to any recommended value, in 5 mph increments, and with differing speed limits for trucks versus other vehicles, different speed limits based on time of day, etc.

Speed limits for state maintained roads in North Carolina as designated by ordinances and the TEAAS (Traffic Engineering Accident Analysis System) database. Speed limits are controlled by general statutes and local and state ordinances. Within incorporated municipalities, the statutory speed limit is 35 miles per hour unless otherwise ordinanced and posted. The statutory speed limit on roads outside the incorporated municipalities is 55 miles per hour unless otherwise ordinanced and posted. Some highways have speed limits of up to 70 miles per hour on certain sections. However, the speed limit along these routes may drop to 55 miles per hour when they pass through certain areas. Speed limits for P5 were pulled Prioritization 5.0 (P5) and from Road Characteristics (TEAAS). The primary routes were edited throughout the other iterations of Prioritizations and therefore these were used for P6.0 and then overlaid with what was in Road Characteristics for Q1 2019. These changes were made manually by the GIS Department.For the purpose of the Strategic Planning Office of Transportation Prioritization 6.0 project (P6), speed limit data is not updated after July 2019. For the P6 application, speed limit data is helpful in aiding the user in selecting a project speed limit, calculating the travel time savings, and helping to calculate congestion criteria.

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.
