Description
Most severely congested corridors on the DRCOG regional roadway system in 2024. DRCOG staff calculates the level of congestion for each segment on the regional roadway system to determine which corridors were most congested. The calculation includes four metrics to determine the severity of congestion: - Severity: How bad does congestion get on the roadway during rush hour? - Duration: How many hours per day is the roadway congested - Magnitude: How many people (traffic volume) are affected by congestion on the roadway? - Reliability: How often do crashes or incidents occur on the Roadway.
Denver Regional Council of Governments (DRCOG) provides data in multiple formats to support a wide range of applications, including Shapefile, GeoJSON, WMS, and KML. Shapefile and KML formats are available as downloadable files. GeoJSON and WMS are provided as URL services. Please note that spatial reference information for GeoJSON and WMS services may need to be adjusted before use in web mapping applications.
