Engineering Services routinely evaluates intersections and roadways to determine if the installation of traffic signals and pedestrian corridors are required. A traffic signal or pedestrian signal warrant procedure is applied to determine the need for new traffic control devices such as traffic signals and pedestrian corridor upgrades.
Traffic signal locations are based on the Canadian traffic signal warrant program. When an intersection exceeds certain criteria and a traffic signal is warranted, the City budgets and plans to have the traffic signal installed. A traffic signal warrant incorporates characteristics such as geometry, operating parameters, local demographics as well as pedestrian and vehicular volumes.
New traffic signals under the Warrant program (2018)
- No new traffic signals are warranted for 2018. The City continues to monitor over 30 intersections for potential traffic signals.
Should an intersection meet the warrant criteria in the current year, the City will budget for and construct a traffic signal in the following year.
Airdrie has several pedestrian corridors marked with signs, overhead signals and in-pavement lights. New signalized locations are selected based on yearly pedestrian control quide studies. The pedestrian control guide considers:
- the number of pedestrians crossing the road and the number of vehicles they must contend with
- the type of road being crossed
- the distance to adjacent protected crossings
- the suitability of the location for this type of control
