Denver--Aurora, CO Urbanized Area Congestion Report
In the line graphs below, FHWA uses Data Collection Year instead of Data Reporting Year to represent snapshot condition/performance at the time the data was collected. More information
The Denver--Aurora, CO Urbanized Area covers parts of Colorado. Targets are agreed upon by several transportation agencies and apply to the entire area.

(Colorado) CDOT coordinated with the Denver Regional Council of Governments (DRCOG) to establish 2- and 4-year targets for PHED in the Denver-Aurora urbanized area (UZA). Targets were established similarly to the travel time reliability targets by using a predictive model. CDOT used a random forest model incorporating data from the National Performance Measure Research Data Set (NPMRDS), Highway Performance Monitoring System (HPMS), FHWA provided occupancy factors, and data from CDOT’s travel demand model. CDOT’s travel demand model includes point data, population data, and long-distance travel estimates. Point data consists of 2015, 2030, and 2045 spatial data which shows the locations of establishments, schools, and homes in the state of Colorado. Population estimates were used at the county level, to ensure we were examining population growth at a more micro level rather than state growth. Long-distance travel estimates were used to factor in travel that originated from outside of the state. After training the model, CDOT tested the results on 2019 data to estimate the performance of the model. CDOT was able to predict known 2019 reliability at accurate levels. Given the accuracy of the model, CDOT forecasted 2023 and 2025 PHED to identify 2- and 4-year targets.

(Colorado) CDOT coordinated with the Denver Regional Council of Governments (DRCOG) to establish 2- and 4-year targets for non-SOV travel in the Denver-Aurora urbanized area (UZA). Targets were established in alignment with DRCOG’s Metro Vision Zero plan, which established an aspirational goal to increase non-SOV travel to 35% by 2040. Using 2020 as the baseline, 2- and 4-year targets were derived by calculating the necessary yearly increase (0.5%) in non-SOV travel to reach the 2040 goal. CDOT and DRCOG used the American Community Survey data set to establish targets.
