Road Weather Information Systems or RWIS provides invaluable data about road weather and the real-time condition of the roadway during winter events.  When RWIS began to be deployed back in the 1990’s the big question was, and still is 30 years later, how many sensor stations should be installed and where should they go.  The Aurora consortium has been looking at this question and recently completed a project on Optimum RWIS Density, Phase 2.  

Dr Tae Kwon from the University of Alberta describes this work and the results he obtained.   For more information on this project visit the Aurora website at https://aurora-program.org/research/completed/optimal-rwis-sensor-density-and-location-phase-2/
