1. Does The City of Calgary have a policy regarding traffic calming?

Yes it does. The policy can be viewed here: Traffic Calming Policy. The current policy is under review in conjunction with the Residential Speed Limits review​.

2. How do I request a community traffic study?

The City of Calgary is currently undertaking a review of residential speed limits, a key factor in how we assess, prioritize, and design traffic calming measures. The outcomes of the review are expected to address many of the concerns that community members regularly raise through the Community Traffic program and Traffic Study applications and may result in traffic calming measures being installed in many locations across the city. As such, we are currently not accepting any new Traffic Study applications until a decision has been made by Council on the Residential Speed Limit Review in Q4 2019.

Though we are not currently accepting new traffic calming inquiries, we are still actively working to:

  • Eliminate sidewalk gaps or missing links that exist in our sidewalk network
  • Enable safe travel for students to and from school (Safe and Active Routes to School program)
  • Assess spot improvements for traffic safety

Citizens are still encouraged to identify locations of concern in their community for these items by contacting 311. Submitting a formal application with resident signatures is not required. To report a traffic safety concern, please complete the following online form, call 311 or 403-268-CITY (2489) if calling from outside Calgary.

3. What is the difference between speed bumps, speed humps, speed tables, and speed cushions?

They all refer to physical measures. These measures vary in shape and size depending on the requirements and function of a particular street for which they are recommended. The table below provides a summary of these measures. Further information is available in Section 4.1 of The Traffic Calming Policy.

4. What is a curb extension?

Curb extensions are curbs that extend into the existing road to narrow it. The narrowed roadway results in a shortened crossing distance for pedestrians.

5. Who is paying for this work?

The City of Calgary funds community traffic calming measures from general tax revenues. The traffic calming plans will not increase property taxes in affected communities.

6. Who decides in which community the next study is undertaken?

A number of communities have requested studies and are on the Community Traffic Study Evaluation List, which is administered by Transportation Planning. While the Residential Speed Limits Review is underway, no new community traffic studies will be initiated. Community members who have already applied for a community traffic study will receive an update from The City in the coming weeks as to the status of their application.
