Photo radar and speed-on-green cameras are being reactivated at Calgary intersections on Friday, following changes to provincial regulations that had previously limited their use. Calgary Police successfully submitted a proposal to the province to reinstate the technology at specific sites based on traffic safety concerns. Interim Police Chief Katie McLellan noted the decision was made in collaboration with the province and aimed at reducing the impact of severe traffic incidents. Some residents have expressed concern about the increase in speeding since the cameras were removed. Louie Paul, who lives near one of the affected intersections, said he’s witnessed more reckless driving in the area.
