CDOT Expands Use of Trip Travel Time Signs in the Denver Area

August 25, 2011 - Denver Metro Colorado/CDOT Region 6 - DENVER - The Colorado Department of Transportation (CDOT) recently added trip travel time messages to two new variable message boards and added a destination to two existing trip travel time signs to provide additional real-time travel information that will help motorist plan ahead.

The following trip travel time information is now available at the following locations:

  • Southbound I-25 at 84th Avenue: This existing variable message sign now displays trip travel times to Speer Boulevard as well as the I-25/I-70 interchange.
  • Southbound I-25 at 58th Avenue: This is an existing variable message board that will now display trip travel times to Speer Boulevard.
  • Eastbound I-70 near 32nd Avenue: This new variable message board will display trip travel times to Wadsworth Boulevard.
  • Eastbound C-470 near Alameda Avenue: This new variable message board will provide trip travel times to US 285.

All of CDOT’s trip travel time signs provide real-time travel information, allowing drivers to estimate how long their trip will take based on present traffic conditions.  It also is useful for comparing normal travel times with the current estimated travel time, allowing drivers to consider the use of alternate routes, if necessary, to help avoid traffic congestion.

All of the trip travel time systems collect data from side-fire speed sensors and toll transponders.  Speed, volume, and road segment travel data is calculated and then the estimated travel time is displayed.  CDOT does not have access to any personal or identifying information on a vehicle and information is deleted from the system within two hours.

Travel times are not predictive but provide a snapshot of current highway traffic and conditions.  Travel time messages and information will not be available during times traffic is stopped or a major incident results in a highway closure.

CDOT currently is displaying travel time data on electronic signs on I-70 west of Denver, in the Denver area along C-470 and 6th Avenue and to the south between Colorado Springs and Lone Tree.  Over the next year to two years, CDOT will continue to expand trip travel time information on I-25 from 84th Avenue to Lone Tree.  The signs will slowly roll out from 84th Avenue and from Lone Tree.
