The City uses various kinds of automated enforcement equipment (generally referred to as photo radar).
Intersection Safety Cameras, known as red-light and speed-on-green cameras, are fully automated and mounted above intersections to capture violations. They are an effective tool in reducing the number of collisions. If your ticket was at an intersection, see the Intersection Safety Device Frequently Asked Questions.
Mobile photo enforcement takes place between intersections, usually from a vehicle parked beside the road. The vehicle-mounted equipment has a narrow radar beam that targets specific lanes of traffic and automatically takes images of speeding vehicles recording the location, date, time, posted speed and violation speed. A trained and qualified peace officer sits with the equipment, observes violating vehicles and makes notes accordingly. The photo radar system is tested before and after the noted offence time.
Peace Officers may also use laser-based, handheld devices that use LIDAR technology. If your speeding ticket is from a hand-held device, the ticket will indicate the images were taken with Photo LIDAR. The images on the ticket will show a grey box on your vehicle in the black and white photo. This box is the target area of the laser so, even if another vehicle passed you at the time the photo was taken, the box indicates your vehicle was speeding. The officer operating the equipment also confirms which vehicle was targeted. The LIDAR system is tested before and after the noted offence time.
