Aurora Project 2005-02 – RWIS Telecommunication Issues and Options

Project Overview

The objective of this project was to investigate the various options for getting RWIS and other data back and forth between remote sites and a central location, while looking for efficiencies of existing and new technologies that reduce costs, ultimately recommending specific technologies and/or methods to reduce telecommunications costs. The benefits of this research include cost savings and performance enhancements as states look to expand the data and services from upgraded RWIS sites.


Public agencies typically operate RWIS, 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 American RWIS. 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 collect by the various sensors deployed to meet the constraints imposed by these collected data products.
