Communication of current road and travel conditions may reduce the number of accidents attributable to winter driving conditions in rural mountain states. During the last 5 years, 61.1% of the total yearly accidents at the study site occurred during the relatively small percentage of time (9.8%) that the road and travel conditions were poor. Use of real-time remote weather information for updating road and travel information was evaluated. Spot speed surveys for different road and travel conditions, road user surveys, snowplow operator reports, and remote weather information system (RWIS) data were analyzed to evaluate the effectiveness of the real-time weather information system. The existing RWIS did not correlate well with the road conditions reported by road users or snowplow operators. An upgrade of the RWIS is needed to improve reliability. The addition of visibility measuring equipment (particle counter) is needed. Additional RWIS sensor location and automatic speed monitoring should also be considered.
