1. Does The City of Calgary have a policy regarding traffic calming?
Yes it does. The policy can be viewed here: Traffic Calming Policy.
2. How do I request a community traffic study?
The City encourages those interested in community traffic studies to review The City of Calgary's Traffic Calming Policy. If, after having reviewed the information you decide to apply for a study, then you must complete the Traffic Issue Reporting Form, found in the appendix of the Traffic Calming Policy, and submit it to Transportation Planning.
Please note that in order for the form submission to be considered complete, you will need to collect signatures from your community association, councillor, police, and from members of your community, as a minimum level of support from the community needs to be demonstrated. The City also encourages you to undertake the community initiatives outlined in Section 3.3 of the policy.
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. The studies are undertaken on a needs basis, determined by an evaluation process and not on a first-come, first-served basis. Community traffic study applications are evaluated in the fall of each year. The Traffic Calming Policy, Section 3.1 provides additional details on the evaluation process.
