Fort Saskatchewan Peace Officers are justifying the use of red light cameras.
They say the cameras have had a sizeable impact on traffic safety in the city.
In September 2016 on Highway 15, in one direction, there were over 241,000 vehicles that travelled through the intersection. 99.8 per cent of those vehicles obeyed the posted speed limit and traffic lights.
"Between 2009, when we first installed the first two intersection safety cameras and 2016, we had 71 per cent fewer red light violations per week across all of our cameras," said Brad Ward, director of protective services.
Fatal and injury-causing collisions in 2009 were 3.989 per 1,000 residents. That number saw a 46 per cent reduction leading up to 2015 to just 2.16 collisions per 1,000 residents.
The number fell dramatically again, by 24 per cent, between 2015 and 2016.
"Our emphasis is always, 'how can we make this intersection safer,'" explained Ward. "We do a lot of analysis looking at how many vehicles are travelling through those locations."
The busiest intersection by far in the city is the Highway 15 and 21 intersection.
Police and Peace Officers urge the public to continue to obey the lights and speed limits, saying their aim is zero collisions.
