Abstract:In an effort to make road and weather information more readily available to travelers and maintenance personnel, Montana is implementing the Greater Yellowstone Regional Traveler and Weather Information System (GYRTWIS). GYRTWIS replaces the existing *ROAD service (which is a non-interactive, recorded message system) with #SAFE, which will be interactive and which will use better weather models, including a new Pavement Thermal Model (PTM). The PTM is a computer model that receives regional weather and information and forecasted weather condition information and generates a location-specific prediction of pavement conditions. The PTM information will be integrated at the #SAFE Operations Center and be disseminated to travelers and maintenance personnel. The road condition and weather forecasts will be available through landline or cellular phones via a 511 telephone system and will ultimately be linked to neighboring states. This evaluation builds upon and complements the ongoing Greater Yellowstone Regional Traveler and Weather Information System (GYRTWIS) evaluation being conducted by Western Transportation Institute/Montana State University (WTI/MSU). The WTI/MSU evaluation of GYRTWIS examines traveler perceptions of system accuracy, availability, usefulness, and understandability, the accuracy and usefulness of the information for maintenance operations, and perceptions of project success.
