Measure for Weather: Non-Intrusive RWIS Sensors are Now, Quite Literally, Hitting the Road

In this article the authors describe the implementation of new non-intrusive road weather information systems (RWIS) sensors to be used in roadway applications. In lieu of sensors embedded in the road surface, newer RWIS use laser spectroscopy that provides information such as road surface conditions (whether the roadway is wet, dry, snowy, or icy), ice thickness should ice be present, as well as snow or water-lay thickness. The Virginia Department of Transportation (VDOT) is taking steps to implement semi-permanent RWIS sensors. Also described is the implementation of such sensing equipment in a mobile platform- a possibility not open to earlier forms of RWIS as they depended upon information gathered by embedded sensors. Finnish engineers have developed such a mobile platform and began testing in 2006, with the instrumentation array mounted at the rear of a vehicle transmitting collected data to an on-board computer.
