Viewing the Data
How currently use it • Deicing efforts • Mobilize faster • Proactively treat roads • Target problem areas • Alert travel public via CMS • Internal alerts • Reduce speed limit in VSL zone • Data provided to public via NWS and News Stations
How could we use it? • Change timing plans • Better predicting and understanding of roadways • Fog alerts • Hydroplaning alerts • Hurricane evacuation
Challenges • GDOT Perception • Alert Oversaturation • Data Comprehension • Personnel Access • Data trust • Public Perception • CMS Messaging • Date Comprehension
Moving Forward • Data sharing with neighboring states • RWIS Expansion • GDOT • Local Agencies • Provide scaled down RWIS for intersection use
