There have been two implementations of Roadway Weather Information Systems in Arizona, known as RWIS Phase 0 and Phase 1. Each Phase has met with limited success and has on-going issues that need to be addressed before new RWIS sites are implemented. This Research Project provides a Communications Plan for Phase 2 and addresses the basic communications problems previously encountered. These include a lack of reliable communications links in rural locations, interchangeability of the RWIS sites and communications infrastructure, and publication of the RWIS data to all interested ADOT personnel. NTCIP standards, newer commercially available communication equipment, and Internet-based publication methods will be used to successfully meet these challenges. Also, a single contractor has been chosen to upgrade existing RWIS sites and install new RWIS sites; thus ensuring a consistent implementation approach and equipment interoperability.
