To ensure safer driving conditions on highways, state highway agencies are exploring the use of new technologies that will improve the flow of information about hazardous road conditions. These technologies are called Road Weather Information Systems (RWIS). The objective of this paper is to provide a systematic methodology for highway agencies to evaluate the costs and benefits associated with implementing RWIS. This objective was achieved through the development of a life cycle cost-benefit model for RWIS. This analysis tool provides highway agency decision makers with a methodology through which different RWIS implementation alternatives can be evaluated from economic, qualitative, and environmental perspectives. A case study demonstrating the use of the RWIS cost-benefit model also is included. The purpose of the case study is to evaluate whether or not it is cost-beneficial to implement an RWIS on Interstate 20 near Abilene, Texas. The model determined that it was cost-beneficial to implement this system.
