In response to concerns raised by local law enforcement regarding unsafe speeds and collision frequency at several intersections, the Calgary Police Service (CPS) has received approval from the provincial government to resume the use of Automated Traffic Enforcement (ATE) at specific locations. 

In December 2024, mandatory restrictions resulted in the removal of ATE on all provincial highways, as well as limiting the use of Intersection Safety Devices (ISDs) for red-light enforcement only on non-provincial roads and connectors. This change also resulted in the removal of speed-on-green ISDs at intersections. 

Law enforcement agencies are permitted to submit a business case exemption request to the provincial government to reinstate the use of ATE at high-risk areas for serious-injury or fatal collisions.

Last year, there were 29 fatal collisions on Calgary roads, a 10-year high. So far this year, there have been 25 fatal collisions in Calgary.

As of Friday, Oct. 3, 2025, ISDs for both red-light and speed enforcement will resume at the following locations:

Both eastbound and westbound 16 Avenue at 68 Street N.E.Both eastbound and westbound Highway 1A at Twelve Mile Coulee Road N.W.

“We thank the provincial government for approving the use of automated traffic enforcement at these locations. They have proven to be dangerous intersections, and we know that implementing this change will make a positive difference for the safety of the community,” says Deputy Chief Cliff O’Brien of the Calgary Police Service. “Automated traffic enforcement has historically played a vital role in the Service’s overall traffic safety enforcement, and we know that speed is a major factor in the severity of collisions. These collisions deeply impact everyone involved, especially the loved ones of those who are killed or seriously injured, as well as the larger community as a whole. As we face another year of increased serious-injury and fatal collisions on Calgary roads, our priority is ensuring everyone’s safety.”

By the numbers

At 16 Avenue and 68 Street N.E.:

There were 37 collisions at this intersection in 2024. Between January and July 2025, the highest recorded speeds at this intersection range from 111 km/h to 192 km/h in the posted 70 km/h zone.

Highway 1A and 12 Mile Coulee Road N.W.:

There were 20 collisions at this intersection in 2024.Between January and July 2025, the highest recorded speeds at this intersection range from 121 km/h to 162 km/h in the posted 90 km/h zone.

The benefits of ATE on all major roadways with high traffic volume, include:

A reduction of the average vehicle speedReductions in total collisions, including injury collisions, fatal collisions and pedestrian collisionsAllowing for adequate and safe traffic enforcement on roads where there is little room for officers to safely conduct traditional speed enforcementMaintaining safer motorist behaviour with the deterrent of fines issues via ATE for driving at dangerous speedsAllowing patrol officers to be available to respond to the already challenging and busy calls for service placed by Albertans on a daily basis

The Calgary Police Service remains committed to working with the province to improve traffic safety and protect all Calgarians on the roads.
