Title:

Road Weather Information System: Phase I (Alaska)

Abstract:

The Alaska Department of Transportation & Public Facilities (ADOT&PF) initiated the first eight environmental sensor stations (ESS) in the Anchorage area, called the Road Weather Information System (RWIS) Phase I. The ESS are used to detect road weather conditions. ADOT&PF maintenance & operations (M&O) use RWIS information to make winter maintenance decisions on snowplowing, snow blowing, deicing and anti-icing. The RWIS information is also made available to the public via roadweather.Alaska.gov or 511.Alaska.gov. ADOT&PF selected a private-sector vendor in October 1999 to complete the following tasks: define user needs; create concept of operations; draft a Request for Proposal to purchase and install ESS equipment; identify existing data sources; complete a vendor reconnaissance; conduct system and field site Plans Specification & Estimates (PS&E), and create a site selection plan. (Project Timeline, pg 3) The ADOT&PF used a site selection plan as a starting point to select Phase I ESS locations (Appendix A).
