Traffic safety initiatives
Strathcona County has implemented a number of initiatives to improve traffic safety, including driver feedback signs, a flashing beacon pilot project and shark’s teeth yield lines.
Driver feedback signs
Strathcona County uses driver feedback signs to educate drivers regarding their travel speed in our community. Built-in radar is used to determine the speed of an oncoming vehicle, which is then displayed on a lighted board. Only vehicle speeds between a specific minimum and maximum limit are displayed.

The rotational driver feedback sign program is now closed for the winter. It will start again in May 2019.
There are now two permanent driver feedback sign locations that run year round:
- Davenport Drive (Eastbound)
- Darlington Drive (East and Westbound)

In 2010, Strathcona County conducted a pilot project to determine if the signs were effective in reducing traffic speeds in residential areas. Analysis of the data collected during the pilot project found that the signs were effective in decreasing driver speeds for a limited period of time. On average, 72 per cent of motorists corrected their speed once they see the sign.
In the urban area, signs are placed mid-block on streets in areas of concern. Fortis Alberta has agreed to let the County use their light standards to mount the signs and accompanying solar panels. Transportation and Agriculture Services has acquired five mobile trailer units which will give us more flexibility in placement of the signs and will allow us to expand to the rural areas.
Since the pilot project showed that positive change in driver behaviour was only demonstrated for a short time, Strathcona County relocates the driver feedback signs approximately every three weeks from May to October.
Strathcona County places the signs based on a priority score determined by resident complaints, Councillor requests, RCMP requests, historical speed data and the presence of vulnerable road users.
Requests for Driver Feedback signs in your neighbourhood can be made through County Connect.
Flashing beacon pilot project
Rectangular Rapid Flash Beacons (RRFB) are solar powered pedestrian crossings. The beacons have LED lights and display intermittent rapid flashes when activated by a pedestrian.
Transportation and Agriculture Services will be installing flashing beacons at three locations in Sherwood Park as part of a pilot project.
- Sherwood Drive/Broadmoor Boulevard Traffic Circle
- Broadway Boulevard
- Cranberry Drive
Traffic safety for vulnerable road users is a priority for Strathcona County. The purpose of installing flashing beacons is to assess their impact on pedestrian safety and driver compliance at marked crosswalks. We will also be testing the beacons functionality during the winter season.
Transportation Planning and Engineering will report the results of this pilot project when completed.
Shark's teeth yield lines
Strathcona County is introducing shark’s teeth yield lines in our community at the crosswalk on Sherwood Drive, adjacent to Salisbury Composite High School. If they improve pedestrian safety, they will be implemented in other locations.

Yield lines in advance of crosswalks indicate the safest place to stop when yielding to a pedestrian to maximize pedestrian visibility for other drivers. A line of painted triangles, also referred to as “shark’s teeth” yield markings, are used as the yield line at mid-block crossing locations. The advance stop or yield line is supplemented with a “Yield Here for Pedestrians" sign.
A multiple-threat collision occurs when pedestrians have to cross more than one lane in each direction. A motor vehicle in one lane stops and provides a visual screen to the motorist in the adjacent lane. The motorist in the adjacent lane continues to move and hits the pedestrian.
The Transportation Association of Canada recently approved shark’s teeth yield lines as an effective method to reduce the chance of a multiple-threat collision.
