For each road segment where a speeding concern is received, a review is first completed to determine if the current posted speed limit is appropriate. This analysis is completed using a set of criteria based on: road geometry (as determined by the Transportation Association of Canada's guidelines), vulnerable neighbouring land use (presence of schools, community centres, parks and trails), history of collisions along the road segment, and observed traffic speeds. Based on this evaluation criteria, recommendations will be made to either maintain or reduce the posted speed limit on each road segment.
After the appropriate speed limit is determined, traffic data is used to determine whether there is a speeding problem on each road using the "85th percentile speed". This value represents the speed that most drivers are comfortable driving at or below. In the urban areas, a speeding problem is considered "confirmed" when the 85th percentile speed is 10 km/h over the speed limit. In rural areas, a speeding problem is considered "confirmed" when the 85th percentile speed is 15 km/h over the speed limit. Where speeding concerns are confirmed, traffic calming measures will be recommended to slow vehicle speeds. These traffic calming measures can include: flexible bollards, digital speed display signs, line painting to narrow travel lanes, and additional speed limit signage.
