Traffic Calming

Traffic calming refers to a set of engineered measures to reduce vehicle operating speeds and improve safety for pedestrians, cyclists and residents. The measures are strategically placed to influence driving behaviour and encourage drivers to be more cautious and attentive.

Pilot project

In 2023, the City implemented a variety of traffic calming measures in deliberate locations to evaluate their effectiveness in addressing traffic safety concerns in our community. During the pilot, we identified three different land use locations:

  1. Residential: Ranchlands Boulevard NE (2024) and Eighth Street SE (2024)
  2. Commercial: Third Street SE downtown at Fourth Avenue SE
  3. Institutional: Eight Street NE near St. Francis Xavier School

Before any measures are implemented, emergency response services perform a test scenario to identify any impacts to access and response times.

The following measures were strategically chosen for deployment:

Curb extensions

During the pilot program, we will use delineators to create temporary curb extensions.

They can take various forms, including flexible posts, cylinders, cones or panels and are designed to be sturdy enough to withstand vehicle impacts, while bending or collapsing upon impact to minimize damage to the vehicle and the delineator itself.

Mini roundabouts

Drivers approaching a mini roundabout must yield to the vehicles already in the roundabout.

In addition to physical infrastructure, traffic calming often involves the use of signage, pavement markings, and landscaping elements to create a visual and psychological environment that prompts drivers to reduce their speed and be more aware of their surroundings.

Staff will review the effectiveness of the pilot measures over a two-year period. Results and learnings will be incorporated into the City’s:

  • active transportation strategy,
  • transportation safety strategy, and
  • transportation master plan.

Future implementation of traffic calming measures may be considered at that time.

How is traffic calming introduced? 
We receive numerous service requests relating to transportation safety concerns such as residential speeding and ensuring our road network is safe for emerging trends such as active or multimodal transportation. 
Identify need 
A preliminary review of the location allows us to identify or confirm potential issues and prioritize for further analysis. 
Data collection and analysis 
We follow best engineering practices and industry standards/guidelines established by the Transportation Association of Canada. We have established warrant assessment protocols for posted speed reviews and pedestrian crosswalks. Staff will deploy tools to measure operating speed and traffic volumes. Site visits and visual observation help confirm the need for traffic control and/or traffic calming measures. 
Identify the appropriate tool and technique to meet the desired outcomes 
Appropriate traffic calming measures are assessed on various factors including road classification/design, traffic volumes, vehicle types (heavy truck/dangerous goods), residential impact, and available road right-of-way. If traffic calming is recommended, the location is placed on a prioritized list for implementation.
