VirtualRWIS (VRWIS) service uses advanced software analytics to make highly accurate virtual observations about ground-level weather conditions at specific roadway locations. The datasets VRWIS offers address the same weather variables typically monitored by the physical Environmental Sensor Systems used by most state Departments of Transportation.
VRWIS uses data from multiple public and commercial sources as inputs to its proprietary road weather software algorithm to generate real-time weather conditions data without relying on physical sensor installations.
