A new smartphone app was developed by the Utah DOT (UDOT) to improve the accuracy and timeliness of road weather information collected and disseminated by a statewide traffic operations center (TOC). As an enhancement to a previously deployed traveler information system (UDOT traffic website and 511 phone system) the new app enabled travelers to submit road weather information directly to a Weather Responsive Traffic Management (WRTM) system and generate high frequency updates to forecast travel information (every 3 hours out 24 hours in the future) on 143 roadway links across the state.
The project initiated in September 2012 was operational by January 2013. Two additional staff (meteorologists) were required to handle the increased data management required at the operations center.
