Federal Highway Administration. Road Weather Management ProgramFederal Highway AdministrationOver the past decade, the Federal Highway Administration\u2019s (FHWA) Road Weather Management Program (RWMP)has championed the cause of improving traffic operations and safety during weather events. The program\u2019s currentemphasis is to encourage agencies to be more proactive in the way that they manage traffic operations during badweather. Weather Responsive Traffic Management (WRTM) is a component major element of the program. WRTMinvolves the implementation of traffic advisory, control, and treatment strategies in direct response to or in anticipationof developing roadway and atmospheric problems that result from deteriorating or forecasted weather conditions.WRTM also includes using weather forecasting to provide proactive advisory and control strategies based on forecastsof weather conditions, and not just traffic responses to those conditions.In 2011, the RWMP initiated a project to collate recent developments and best practices in WRTM, identifyimprovements to the strategies, and develop implementable Concepts of Operations. As a follow-on task, threeconcepts were selected for further implementation and real-world deployment. This report documents theimplementation of one of those concepts relating to weather responsive traveler information. This concept focused onan initial implementation of a citizens reporting system and was conducted in partnership with Utah DOT. This reportdocuments the system design, operation, evaluation, findings and lessons learned from the implementation.Considering this was the first opportunity to implement a limited citizen reporting program, the results are encouraging.Fifty-six UDOT employees were trained, 89 of 143 road segments were covered, and 607 reports were submittedduring the 2012/2013 winter season. Report accuracy was very high (over 99%), and they provided increasedsituational awareness for TOC meteorologists and operators. Public response to this program was quite positive.Lessons from this initial implementation will help UDOT further develop and move this program forward and serve as avaluable model for other state DOTs that seek to implement similar improvements
