Crowfoot Valley Road traffic control visioning

Crowfoot Valley Road map with Sapphire Pointe, Diamond Ridge, Timber Canyon, Knobcone intersectionsAs the Town grows and traffic volumes increase on Crowfoot Valley Road, we know that you care about the safe and efficient travel along the roadway. The Town has developed an initial traffic control vision to meet the goals the community values.

The Town values community input and is seeking feedback. There are a few options that best accommodate this growth at each intersection along Crowfoot Valley Road: Sapphire Pointe Boulevard, Diamond Ridge Parkway, Timber Canyon Drive and Knobcone Drive.

Summary of Input

Thank you for your feedback; the input form is now closed. Staff has reviewed all of the written and verbal input received through the public process. The key themes are:

  • concerns about vehicle speeds on Crowfoot Valley Road
  • feedback that Crowfoot Valley Road needs to be widened sooner than later, 
  • keeping right turn lanes now and after the road is widened
  • safety of the northbound left turn lane at Diamond Ridge Parkway
  • various opinions about what the best traffic control option is for each intersection

In addition, answers to frequently asked questions can be found below. Staff will be reviewing the public input along with any proposed changes to the recommended capital plan for Crowfoot Valley Road with Council on April 20, 2021, for feedback and direction. 

Traffic control options

The following traffic control options are being considered based on the future traffic volumes on Crowfoot Valley Road and the existing intersecting streets:

Traffic signal: This type of control works the best when the volume of vehicular traffic on the main street is much higher than the intersecting streets, and is consistently heavy throughout the majority of the day. The drawbacks to a signal is that they are not efficient during the majority of the day if traffic volumes ebb and flow. Signals can generate increased noise and vehicle emissions due to the regular start and stopping of vehicles. Speeds remain unchanged on the main street. Signals must also meet engineering criteria to support their installation, which means that they cannot be constructed prior to certain conditions. This is because signals that are installed outside of these conditions can actually contribute to certain types of accidents.

Roundabout: This type of control works best when the volume of vehicular traffic on the main street is high, but not constant throughout the day. They work well at transitions between land uses (rural to urban) as they slow traffic down on the main street. Because of decreased speeds through the roundabout, accidents that do occur are typically limited to vehicle damage, versus fatalities or injuries. Roundabouts reduce vehicle emissions and noise due to reducing the number of vehicles that must stop and idle. Roundabouts are not effective on steeper roadway grades due to larger vehicles being subjected to tipping incidents if heavily loaded.

Two-way stop: This is where the intersecting street(s) must stop for traffic on the main street (current for all four intersections). This control works well when there are sufficient gaps in traffic along the main street to allow for turning vehicles to safely enter the main street traffic.  When gaps decrease during certain periods, and vehicles have to wait longer, the risk of accidents increases. The safety and efficiency of two-way stops can be improved through the use of an acceleration lane, or by restricting certain turn movements if options to accommodate these movements nearby exist.
