Traffic Congestion

Traffic Congestion

Travel Time Delay is the ratio of peak-period travel time to free-flow travel time for the afternoon peak period (5:00 PM – 6:00 PM) for critical corridors in Arapahoe County, excluding I-25, I-225, and I-70.

Assesses the vehicle congestion that Arapahoe County residents and corridor users will encounter during their afternoon peak-period commutes. Efficient travel is important for quality of life and fostering a safe and vibrant County.

Low – Travel Time Delay is one measure of congestion, which is a reflection of usage during peak hours on the corridor.  Improvement in this index will require a multi-pronged approach that will take into consideration physical, programmatic, operational, and mode shift/opportunity factors and will require the involvement of and coordination with various entities.

The TTI is down from the previous year due the COVID-19 response implemented by the Denver Metro area.
