CTDOT Historical Traffic Monitoring Data
The CTDOT Historical Traffic Monitoring GIS Data is a curated geospatial dataset integrated into the agency’s enterprise platforms, including the TED Portal and Open Data Hub. It supports transportation planning and safety analysis by providing historical traffic volumes and patterns across Connecticut’s roadway network. Managed by the Enterprise GIS Unit, the data is structured for internal use via ArcGIS Enterprise and selectively published to the public-facing Open Data Portal. It is actively maintained and synchronized through automated replication processes, although recent updates indicate occasional export issues requiring manual intervention. The dataset is also referenced in strategic planning tools and dashboards, and plays a key role in initiatives like the Highway Safety Road Map and the SMART grant application for connected infrastructure.
