Dumfries Avenue Traffic Calming Review

1. What is traffic calming?

Traffic calming refers to measures that reduce traffic speeds and/or cut through traffic. Traffic calming measures are designed to reduce the negative effects of motor vehicle use, help alter driver behavior and improve conditions for all street users notably vulnerable street users like pedestrians and cyclists.

2. What are the different approaches to traffic calming?

Traffic calming approaches are divided into three categories of passive, moderate and restrictive approaches. 

Passive traffic calming measures generally do not affect the physical geometry of a roadway but can help increase awareness. Some examples include signage, textured pavement and roadway painting. Passive traffic calming approaches are low in cost but studies show that they typically are less effective than moderate or restrictive approaches.

Moderate traffic calming measures include horizontal and vertical measures which cause a vertical or horizontal deflection of the vehicle. Studies show that moderate traffic calming measures reduce through traffic volume and speed. Some horizontal traffic calming measure examples include chicanes, median islands, curb extensions, traffic circles and pedestrian refuge islands. Examples of vertical traffic calming measures include raised crosswalks, speed cushions and speed humps. 

Speed bumps as found in locations such as parking lots are not installed on city streets. The city uses speed humps which are less abrupt and are designed to calm traffic to speeds between 30-40 km/h.  

Restrictive traffic calming is effective in eliminating through traffic volume by limiting/making changes to roadway access. Some examples include partial road closure, full road closure, diverters and one-way roadways. Restrictive traffic calming approaches have medium to high installation costs and are not typically considered on major collector roadways or roadways that are identified as emergency response routes or transit routes.

3. Why is Dumfries Avenue being considered for traffic calming?

• Ranked 1st on The City's warranted traffic calming priority list with 52 points; 
• Designated as a Minor Collector roadway with a posted speed limit of 40 km/h; 
• Recorded 85th percentile speed (at which drivers travel at or below): 56 km/h;
• Recorded AADT (average annual daily traffic): Approximately 2938 vehicles;
• Identified concerns include speeding and traffic volumes, which can be addressed through the traffic calming review.

4. What is the required level of residents’ support for a traffic calming plan to be initiated and implemented?

Initiation Support 

Impacted residents must demonstrate 25% support to initiate the traffic calming study. At this stage, we survey residents to vote on whether or not they would like to see the review initiated. Your feedback is an important first step. Please take our five-minute survey to let us know what you think.

Implementation Support

There will be a second survey near the end of the traffic calming review to determine if there is support to implement the preferred plan developed by staff and residents. This final survey requires that 50% of residents respond, with 60% in support of the preferred plan before work can proceed.

5. What factors will be considered for selecting traffic calming measures?

Resident feedback, current traffic conditions such as speed, volume and collision history, potential impacts on other adjacent roadways, possible inconvenience to residents, potential impacts on emergency services and public transit, potential impacts on maintenance operations (snow removal), construction cost and maintenance cost are some of the factors considered when selecting the traffic calming measures.

6. Can an all-way stop control be used as a traffic calming measure?

It depends on traffic volumes for each of the intersecting streets. All-way stop controls are meant to safely alternate the right-of-way to opposing traffic flows. Based on the Ontario Traffic Manual, in order for an all-way stop control to be warranted, a significant amount of traffic must exist on both streets. If there is little traffic on the side street, drivers who regularly use the major streets will start anticipating that they will not have to yield to anyone and may disobey the stop signs. Unwarranted all-way stop controls are more often disobeyed by drivers and as a result pedestrian safety can be compromised.

7. Can more police enforcement be used as a traffic calming measure?

Many residents across the Region request police enforcement as a mean of traffic calming. City of Kitchener (and other Waterloo Region municipalities) work with Waterloo Regional Police Services (WRPS) in order to help identify areas with persistent traffic concerns. We flag priority streets to the WRPS for the Selective Traffic Enforcement Program (STEP) on a quarterly basis. WRPS will attempt to provide these areas with added enforcement over each quarter of the year.

8. What are the steps involved in the review?

We will survey residents who are affected by the traffic calming review to vote whether or not they would like to see the review initiated. City staff will review and summarize the resident feedback and the current traffic conditions. Assuming residents voted to move ahead with the review, a design concept will be developed based on the results to date. The design concept will be presented to the residents at a Public Information Centre (PIC). The design will also be circulated to affected agencies such as operations, waste management, emergency services and transit. 

Based on the feedback received, a preferred plan will be presented to residents. Residents will then be surveyed to vote on the preferred traffic calming plan to determine if there is support to carry out the plan. The results of the traffic calming review including voting results will be presented to Council. If approved by Council, the design will be implemented. A follow up review will be completed at least one year after the plan to measure effectiveness and neighborhood satisfaction.
