Abstract: As far back as 25 years ago, sensors were developed to determine the temperature and condition of road surfaces. Unfortunately, not a lot was known (or thought) about the road environment and sensors were not wisely placed. Also, the early sensors were unreliable. In the last 15 years or so, a great deal of effort has gone into developing reliable sensors. Along with, and in some cases paralleling sensor development, (far-sighted) meteorological practitioners and road authorities recognized future knowledge of the weather and perhaps more importantly road conditions, might allow snow-and-ice control decision makers to do their job better. I'm happy to report that because of the work of a few individuals in both camps, the technology is here. We are seeing a new term ... Road Weather Information Systems (RWIS). What is the RWIS technology, who can use it, and why should anyone use it? This paper will describe the role of a Strategic Highway Research Program (SHRP) project which was designed to answer those questions. Following an introduction to SHRP, the project's objectives will be presented. Next, the paper will describe the current project status, including findings to date, future work, and products to be delivered will be discussed. Finally, other research will be discussed.
