Description: This feature class consists of approximately 195,000 features representing over 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 dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. Multi-part geometry is created where routes are noncontiguous (e.g. a valid physical gap exists because another route is the master). The feature class only depicts master routes, those are routes built in the prime direction and on divided roadways where the non-prime direction is the master. Each road centerline record has a master route record assigned.
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).
Purpose:
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.
Note: The overlap and non-prime measures are for reference only and have not been fully validated for accuracy or completeness.
