About the research
The Aurora Pooled Fund program public road agency partners have a need to better plan for on-going costs associated with Road Weather Information Systems (RWIS). This project will develop guidelines for determining RWIS long-term, life cycle costs and will ultimately help answer questions such as: 1) What is the optimal point for agencies to replace RWIS components? 2) What level of RWIS replacement funding on a per site basis is needed each year to achieve a corresponding target class age over a 3, 4 or 5 year period? 3) How should agencies address and fund the replacement or repair of components where the technology is constantly changing (such as communications)? Life cycle cost considerations will include capital costs (such as hardware and software) and future costs (such of ongoing operations, maintenance, rehabilitation, communications and replacement costs). Life cycle RWIS costs will be provided per site as well as for individual RWIS components, if possible.
