Southmore Drive East Traffic Calming Study

On this page
Project status


The City of Ottawa has completed a traffic calming study for Southmore Drive East between McCarthy Road and Walkley Road in response to traffic concerns raised by residents. The purpose of this study was to recommend permanent roadway modifications intended to improve safety, primarily by reducing vehicular speeds.  

This study focused on key locations and potential recommendations within the means of the Neighbourhood Traffic Calming (NTC) program. Traffic calming is the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behaviour, and improve conditions for non-motorized street users.


Virtual Public Meeting

A virtual public meeting was held on March 9, 2022. An overview of the study and proposed concept design was presented, followed by a questions and answers period.

Community Feedback

An online survey was conducted between February 15 and March 18, 2022 to seek community feedback on the proposed concept design. Survey respondents demonstrated strong support towards the proposed traffic calming measures. However, almost a quarter of the respondents felt there should be some modifications to the plan. The main concerns respondents expressed regarding this study area were pedestrian safety, cyclist safety, vehicle speeds, and limited visibility at certain locations.

Final Functional Design Plan

Based on traffic data, coordination with various stakeholders, public feedback and other project constraints, City staff are recommending to proceed with the measures proposed in the February/March 2022 concept plan, plus a few additional measures.

The final recommended functional design plan for Southmore Drive East includes:

  • 4 sets of speed cushions to slow vehicular traffic as it travels along Southmore Drive East.
  • Edge lines on both sides of the street to visually narrow the roadway.
  • Raising the existing crosswalk across Southmore Drive East at Walkley Road to improve pedestrian visibility and address drainage issues.
  • A short sidewalk segment on the west side of Southmore Drive East from Walkley Road to Garwood Avenue. The sidewalk is planned to narrow the roadway to:
    • assist in reducing speeds, and
    • minimize the impact to the front lawns of 2908 and 2918 Southmore Drive East.
  • Removal of on street parking adjacent to the new sidewalk as the available road width will be reduced by about 2 metres.
  • Removal of on-street parking on the inside of the curve near Linton Road to improve visibility.

Renewal of the pedestrian landing pads at the McCarthy/Southmore intersection is also planned to be implemented in conjunction with the traffic calming measures on Southmore Drive East (though this work will be funded through a separate program).

Next Steps

The approved traffic calming plan is now in the  detailed design and construction phase. Construction timing is to be confirmed but is currently anticipated to be in 2024.

Frequently asked questions (FAQ)

Below are project-specific questions and responses that were received during a pre-consultation meeting held by the Community Association. General FAQ about traffic calming can be found online.

If you have other questions, please reach out to the City contact below.

Can a continuous sidewalk be added to Southmore Drive East as part of this project?

Adding a continuous sidewalk is outside of the scope and available budget of the Neighbourhood Traffic Calming Program. The City has separate programs which review and prioritize sidewalk requests. 

Through collaboration with another City program, this project was however able to add the short sidewalk segment from Walkley to Garwood, where the greatest degree of concern for pedestrians was identified.

Can implementation of this project be accelerated?

The City will attempt to accelerate the timeline as much as possible, however there are several factors that contribute to the schedule including stakeholder input, resource availability, design processes, construction seasons, nearby projects, funding, etc.

Are speed cushions effective at reducing speeds?

The degree of effectiveness of traffic calming measures including speed cushions vary depending on many factors such as the context and width of the road, existing speed, etc. Vertical measures (speed cushions/humps/tables) are amongst the most effective measures at reducing speeds and are also cost-effective.

Further information on traffic calming measures.

How is winter maintenance affected by speed cushions?

Road maintenance crews may need to use more salt on the speed cushions and run more passes, however there are no major requirements/challenges reported to date.

Are the speed cushions accessible for all users travelling on the roadway, considering that there are not continuous sidewalks along Southmore Drive East?

The speed cushions will be constructed within the City’s Accessibility and AODA guidelines. The slopes will be no steeper than an accessible ramp.

How are bicycles affected by the speed cushions?

Bicycles can navigate the speed cushions easily - they can go over them or in-between. A speed cushion is designed such that the impacts on vehicles, including bicycles, is low if the speed of the vehicle is equal to or less than 30km/h. Cyclists are encouraged not to ride bicycles at speeds higher than 30km/h.

Accessibility is an important consideration for the City of Ottawa. If you require special accommodation, please contact the City of Ottawa Project Manager.
