Abstract:Weather-responsive management strategies (WRMS) help transportation agencies manage and operate their system in challenging road weather conditions. Anti-icing, plow routing, variable speed limits (VSL), and variable message signs (VMS) are examples of WRMS. Effective WRMS require sufficient information on traffic and weather conditions and development of infrastructure and systems to support implementing the chosen strategies. Federal Highway Administration’s (FHWA) Road Weather Management Program (RWMP) has worked to advance WRMS in programs directed at fixed sensor and connected vehicle (CV) data collection, strategy development, decision support systems, and agency implementation support. In addition, analysis, modeling, and simulation (AMS) tools have been used by FHWA and agencies to assess the effectiveness of these data sets, strategies, and methods in improving the operational response. This project evaluated existing AMS tools and researched agencies that use or plan to use CV data for WRMS and want to evaluate their existing and enhanced practices. Site recommendations depended on the availability of CV data, WRMS in use, and calibrated AMS tools for those sites. Agencies and sites considered for this effort were currently implementing weather-responsive management strategies, collecting CV or mobile data, and using or interested in using an AMS tool for evaluation. AMS tools must also be applicable to the particular strategies and fully implementable on the agency’s transportation network. Using these considerations, the RWMP partnered with Wyoming Department of Transportation (DOT), University of Wyoming, and City of Chicago DOT. This flyer summarizes these case studies and results.
