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, interoperability of the RWIS sites and communications infrastructure, and a 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. |
