Benefit Summary HTML

The Utah Department of Transportation (UDOT) Weather Operations/ Road Weather Information System (RWIS ) program is unique among state departments of transportation nationally, as it assists the DOT operations, maintenance, and construction functions by providing detailed, often customized, area-specific weather forecasts. Staff meteorologists are stationed in the Traffic Operations Center (TOC), providing easily accessible weather information and quality control of weather forecasts. A national survey confirmed the benefits of such customized forecasts, including more accurate forecasts, timely forecasts and access to a forecaster, advanced warning of storm conditions, better response time and improved planning and scheduling of staff, and better use of chemical products.
