Abstract

Public Agencies typically operate Roadway Weather Information Systems (RWISs), which provide transportation managers and maintenance crews with a key source of timely and accurate weather information for guiding operations during adverse weather events. Jurisdictions employ a variety of local area and wide area communications schemes to centrally collect and aggregate environmental data from spatially-distributed RWIS sensors. We were interested in determining best practices and gaining further understanding of the commonly-deployed communications schemes in use for North America RWIS systems. The objectives of this study were to present and describe the categories of communications systems enabling the transmission of field-collected environmental data to centralized data collection and management facilities; review the types of data collected by the various sensors deployed within participating jurisdictions; and detail the communications requirements and communications solutions deployed to meet the constraints imposed by these collected data products.
