Traffic improvement projects
Calgary is growing both in population and in infrastructure, and with this growth comes impacts to traffic on our roadways. To address this issue, The City has developed the Traffic Operational Improvements program (TOI).
The program evaluates various intersections across Calgary that require operational improvements for a variety of reasons like traffic congestion and safety issues. Once an intersection meets the necessary criteria of the TOI program, a temporary traffic pilot or, in some cases, permanent traffic measures will be proposed for installation. Traffic pilot and/or permanent traffic measures could include:
- Changes to signal timings
- Temporary roadway restrictions
- Additional permanent turning lanes
Traffic improvement projects
Auburn Bay - Mobility safety improvements
In the summer of 2024, temporary traffic calming measures will be put in place to improve safety along two corridors: Auburn Shores Way S.E. and Auburn Sound Manor S.E. These safety improvements are being considered in response to findings from a recent safety and operational review looking at operational speed and collisions in the area.
Proposed changes include:
- Installation of temporary curb extensions along the two corridors
- Median extensions.
- Crosswalk enhancements.
- Painting shoulder lines along the corridors to reduce travel lane width.
- Installing temporary speed humps in select locations.
Cranston Avenue S.E. - Mobility safety improvements
In the summer of 2024, temporary traffic calming measures will be put in place to improve safety along Cranston Avenue S.E. These safety improvements are being considered in response to findings from a recent safety and operational review looking at operational speed and collisions in the area.
Proposed changes include:
- Installation of temporary curb extensions along the corridor
- Reducing the posted speed limit to 40 km/h.
- Crosswalk enhancements.
- Painting shoulder lines along the corridor to reduce the width of travel lanes.
Hidden Valley - Mobility safety improvements
In the summer of 2024, temporary and permanent traffic calming measures will be put in place to improve safety along three corridors: Hidden Creek Drive N.W., Hidden Creek Boulevard N.W. and Hidden Creek Way N.W.
Proposed changes include:
- Installation of temporary curb extensions along the three corridors
- Reducing the speed limit to posted 40 km/h
- Installing temporary speed humps in select locations
- Converting existing temporary roundabout to permanent in the summer/fall 2024
This is in response to feedback from the community. A recent safety and operational review of the three corridors indicated that the changes are expected to improve safety by reducing incidents and near-misses involving motorists, cyclists, and pedestrians.
Heritage Meadows Way and T&T Supermarket/ Real Canadian superstore Entrance – Northbound and southbound left turn bays
The lack of northbound and southbound left turn bays at this intersection has raised safety/operation concerns since the traffic signal was installed in 2020.
These issues include:
- Very long southbound queue of traffic, backing up to Heritage Drive at times.
- Last second northbound/southbound lane switching maneuvers due to a lack of turn bays.
To address these issues:
- Northbound and southbound left turn bays will be constructed.
- A southbound signalized left turn arrow will be added to reduce the risk of traffic backing up to Heritage Drive.
With these operational improvements, the overall intersection delay will be reduced by approximately 30% in peak hours on weekdays and 50% on weekends.
Kensington Road from Crowchild Trail to 14 Street N.W. – Safety improvements
In the summer of 2023, temporary measures were put in place to improve safety along Kensington Road from Crowchild Trail to 14 Street N.W.
Changes include:
- Reducing to a single lane in each direction.
- Extending curbs along the corridor and most crosswalks.
- Installing rapid flashing beacon lights at crosswalks.
- Extending the existing 40 km/h speed limit.
This is in response to findings from a recent collision review and traffic assessment of the area. The changes are expected to reduce incidents and near-misses between motorists, cyclists and pedestrians.
Sarcee Trail - 112 Avenue N.W. to Stoney Trail – Three southbound through-lanes
Thorough analyses on collision history, operations, and geometric design along Sarcee Trail from 112 Avenue to Stoney Trial, various operational and safety issues have been identified.
To address these issues:
- Three southbound through-lanes will be constructed between 112 Avenue and the Stoney Trail boundary,
- The eastbound right turn yield at 112 Avenue will be converted to a free flow right turn movement,
- A second southbound left turn lane will be constructed at the Beacon Hill Shopping Centre intersection with a protected-only operation for both north and south bound left turns.
With these improvements:
- The risk of eastbound/southbound right turn collisions at 112 Avenue is expected to be reduced significantly,
- The eastbound free flow right turn movement at 112 Avenue will enhance operations for trucks entering Sarcee Trail,
- The increased southbound capacity will improve corridor operations for future traffic growth.
