Annual Average Daily Traffic

Published by Connecticut Department of Transportation | State of Connecticut | Catalog Last Checked: September 10, 2026 at 06:41 PM | Dataset Last Updated: August 24, 2026
A collection of layers maintained by the Traffic Monitoring Unit. The traffic signal control area polygons were developed by the CTDOT and updated by UConn and VHB. The feature class was developed by digitizing the area that represents the geographic extent of the signalized intersections. Attributes were migrated from the previous system and only the intersection number has been maintained. Long term plans are to remove some of the fields and migrate them to correct geographic asset in the signals data model. This will preserve the asset lifecycle.
