The Causes of Congestion tool automates the process of identifying and quantifying the causes of congestion in eight primary categories: (1) Recurrent (2) Weather, (3) Work Zones, (4) Incidents, (5) Signals, (6) Holiday Travel, (7) Multiple Causes, and (8) Unclassified. Within the interactive interface, users can explore causes of congestion patterns at the National, State, and County levels.
