Wyoming Department of Transportation (WYDOT) road condition reporting application for weather responsive traffic management.

Federal Highway Administration’s (FHWA) Road Weather Management Program (RWMP) strives to promote the development and implementation of cutting-edge techniques for maintaining safety, mobility, and productivity of roadways during adverse weather conditions. A particular Weather Responsive Traffic Management (WRTM) strategy developed and described in this report involves mobile data collection and reporting system in Wyoming for road weather information during weather events. A concept of operations and an evaluation plan were developed and utilized in the project. The objectives of the system were to improve the efficiency of road condition reporting and actions taken in the Traffic Management Center (TMC), the timeliness of updated traveler information, and the situational awareness of field maintenance staff. This report documents the implementation and evaluation of the system. Overall, the evaluations indicate improved effectiveness and efficiency of road condition reporting and traffic management center activities during weather events. Furthermore, improvements in the TMC data management systems, frequency of road reports, and field information accuracy were also noted. The report contains the description, development, and implementation of the system; the evaluation approach and results; and conclusions, lessons learned, and recommendations based on the evaluation results.
