LRS Road Intersections

<p>SDE_VDOT_INTERSECTION_W_XY - Latitudinal and Longitudinal Junction Coordinates - Generalized placement of event data.</p><div>&nbsp;</div><div>Abstract: This feature class consists of approximately 445,000 features representing roadway intersections throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Roadway Inventory Management System (RIMS), the source system of record for road inventory. The Linear Referencing System (LRS) data contained within this feature class consists of Latitudinal and Longitudinal coordinate points portraying at-grade intersections, single/divided centerline geometry transitions and jurisdiction boundary changes on Virginia Department of Transportation maintained roadways. The data layer also provides a cross-reference between Roadway Inventory Management System (RIMS) "nodes" and the current Linear Referencing System (LRS) "junctions". This intersection extract has latitude and longitude coordinate attribution derived from the "FROM" and "TO" junctions where a valid INTERSECTION_ID (i.e. HTRIS node) exists.&nbsp;</div><div>&nbsp;</div><div>Purpose: This linear referenced data layer provides the junction point geometry for the underlying spatially enabled geometric network and a method to locate "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, turns, etc...) relative to Linear Referencing System junctions.</div>
