ALASKA'S ROAD WEATHER INFORMATION SYSTEM : UNIQUE DEPLOYMENT IN A RURAL ENVIRONMENT

Résumé fourni par la source

The Alaska Department of Transportation and Public Facilities (ADOT&PF) is deploying a statewide Road Weather Information Systems (RWIS) network as part of their regional Intelligent Transportation Systems (ITS) architecture, the Alaska Iways Architecture Implementation (AI2). In Phase I, ADOT&PF installed 8 RWIS sites in the Anchorage area as a prototype to establish the type of equipment site construction standards, and operational issues for future RWIS installations. Phase II calls for up to 31 additional RWIS in some of Alaskas most remote and extreme weather prone areas of the surface transportation network. Rural Alaska presents considerable challenges to a RWIS deployment: limited access to communications and power extreme weather and environmental conditions, and long distances from services to support the RWIS sites. These challenges have led ADOT&PF to use innovative procurement and deployment strategies and form partnerships with other agencies in power, communication, data collection and sharing, and web dissemination. These unique methods have enabled ADOT&PF to reduce costs, increase efficiency and maximize usefulness of the RWIS
