Abstract:The Department of Transportation and Public Facilities (DOT&PF) has a network of Road Weather Information System (RWIS) environmental sensor stations (ESS) deployed along the road network. Six of the stations do not have access to commercial power and are off-grid. DOT&PF has used power modules with propane generators for these sites for the past 12 years. The generators and electronics have outlived the life expectancies and all of the sites have failed.
New technology was suggested in the “Review of Power Sources for Alaska DOT Road Weather Information System (RWIS): Phase I” final report completed in August, 2014 with the Institute of Northern Engineering. This report documents the installation of a Thermoelectric Generator (TEG) at the Divide Road Weather Information System (RWIS) Located at mile post 11.7 on the Seward Highway.
