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.
Traffic volumes in 2023 have continued to increase from the significant decrease during the pandemic. The Travel Time Index is still performing well below the 2019 levels and can be partially be attributed to the change of travel behavior. Although traffic volumes have increased, the time vehicle trips occur are more evenly distributed over the hours between 7 AM to 6 PM.
