Commonwealth of Virginia Department of Transportation 20190129 Original vector digital data Richmond, Virginia Spatial Intelligence Group | EDM | ITD | Virginia Department of Transportation withheld This feature class consists of approximately 1,750,000 features representing around 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS). Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides route centerline geometry that is segmented at each intersection and supplies key descriptive attribution for each segment (i.e. edge) record. The feature class also depicts overlapping routes (e.g. Interstate 64 and Interstate 95) as two separate collinear features, one on top of the other. Routes built in the prime and non-prime directions are included. Each road centerline record has a master route record assigned. In addition, local Virginia Geographic Information Network (VGIN) street names are attributed to each edge where possible. Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions). Note: The overlap, non-prime measures and street names are for reference only. These measures and street names have not been fully validated for accuracy or completeness. This linear referenced data layer represents roadways that are maintained by the Virginia Department of Transportation and provides the underlying spatially enabled geometric network to which all "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, etc...) can be located. Version Release Documentation: Contained within all Linear Referencing System data release packages are comprehensive release notes (e.g. “LRSx.x Release Notes.pdf”, where the x.x corresponds to the release version). These notes outline pertinent information concerning the release and provide general reference about the LRS. To determine which Linear Referencing layer will best suit your needs, see the appendix portion of the release notes for a Feature Class Application Matrix. 20190129 publication date In work Quarterly -83.656310 -75.344460 39.440930 36.536870 ISO 19115 Topic Category Transportation Virginia Department of Transportation VDOT Linear Referencing System LRS Roadway Network System RNS Roadway Inventory Management System RIMS Spatial Intelligence Group SIG Routes Roads Interstate Primary Secondary Frontage Ramp Edge Overlap Official State Mileage OSM Virginia Commonwealth of Virginia 20190129 LRS Release Version 19.1 Disclaimer: The Virginia Department of Transportation's digital data files are for use in performing the official business of the Commonwealth of Virginia.

Richmond Virginia 23219-2052 USA 804.786.1999 COITDSIG@VDOT.Virginia.Gov 9am - 5pm EST/EDT, M-F This data was created as part of a joint effort between the Geographic Information System Program Office and the Roadway Network System Program, both contained under the Information Technology Division of the Virginia Department of Transportation. It also includes street names from the Virginia Geographic Information Network Master Centerlines. © Copyright 2019 Virginia Department of Transportation - All Rights Reserved Internal VDOT Policy Unclassified 20190129 vector digital data Richmond, Virginia Virginia Department of Transportation Business attribute components for all Virginia Department of Transportation maintained routes are derived and maintained within Roadway Inventory Management System (RIMS). The attributes in Roadway Inventory Management System (RIMS) are field checked when a route is first created by the Maintenance Division or when modifications to existing routes are identified. The Roadway Network System continually reviews business processes and works with the business units to ensure the proper attribution is maintained as changes occur. Mechanisms developed for the business unit allows them to identify attribute incontinences if they should occur. The Linear Referencing System build process analyzes constructed routes determining if they are topologically continuous. Internal business rules dictate all necessary deviation from the aforementioned determination. The Roadway Inventory Management System (RIMS) is the source system of record for this layer. The Roadway Network System (RNS) will replace Roadway Inventory Management System (RIMS) and become the source system of record for this layer. The Roadway Inventory Management System (RIMS) source data is split into two components, a business attribute component and a location component. Business Component: The business attribute component contains all records in the Roadway Inventory Management System (RIMS). Location Component: There is currently a lag between the time a roadway is physically constructed and when it is entered into Roadway Inventory Management System (RIMS) and then ultimately depicted the Geographic Information System Centerline. Computer-Aided Design files and local data are used where necessary. Ortho-rectified imagery is used in the creation and update process to ensure alignment. The Roadway Network System models Roadway Inventory Management System (RIMS) and contains all location information, additional non-prime centerlines for divided primary and secondary routes and urban and street named networks. Currently the Roadway Network System contains most Roadway Inventory Management System (RIMS) routes with a high degree of completeness for each route (95%+). Comparisons between the Roadway Inventory Management System (RIMS) and the Roadway Network System networks will attempt to address all inconsistencies before the Roadway Network System becomes the source system of record. The Roadway Network System is based on creating a measured anchor section for each segment of the route. Detailed comparisons were done in the automated data conversion processes between the Roadway Inventory Management System (RIMS) Link and Node based system and the Roadway Network System Anchor Section and Anchor Point based system to ensure completeness. Manual steps are being developed to handle special cases such as loop and loop back routes that were not possible to automate. Horizontal accuracy for this layer can be defined as the probable error as measured along the linearly referenced route between reference calibration points. Such errors are largely dependent upon the degree of polyline resolution and the spatial alignment of the roadway with the actual centerline. Known reference point locations with known Official State Mileage values are used to ensure calibration of routes. 53 feet +/- 0.01 miles Precision of the mile points in the Roadway Inventory Management System (RIMS) is 53 feet (+/- 0.01 miles). Conversely location information may not have been recorded in the source system of record accurately such that errors of >0.1 miles can exist.
