The City is continually being proactive in improving efficiencies, while reducing costs and carbon emissions. Below we have provided some interesting information about our traffic signal program:
How Traffic Signals Operate
- All traffic signals "rest" on the green on the main street until there is a request to change from a vehicle or pedestrian on the secondary street.
- The light will change when a vehicle approaches the intersection or when the pedestrian crossing button is pushed. If the vehicle passes the stop bar, the controller thinks the vehicle went by and the light will not change.
- The changing of the traffic signal will not speed up by pushing the pedestrian button several times, as the controller only accepts the signal once per cycle.
- All of our intersections use cameras for video detection to sense oncoming traffic to synchronize the traffic pattern. The City does not record or store data.
Traffic Signal Maintenance
- The traffic signals on Lougheed Highway are maintained by the Ministry of Transportation and Infrastructure with the exception of the downtown core. The City maintains the traffic signals from 223 Street and Lougheed Highway to 116 Avenue and Lougheed Highway.
- The City maintained intersections have uninterrupted power supply. This is a system using batteries to power the intersection for a period of time after a hydro power outage. An intersection can be powered by batteries between 6 to 12 hours.
- The City maintained traffic signals all use LED technology to increase energy efficiency and long life span.
- The City has moved to wrapping traffic control cabinets in a plastic coating displaying various scenic pictures. This program enhances the visual appeal while reducing the cost of removing graffiti.
Red Light Cameras
Red light cameras are installed and maintained by the Ministry of Transportation and Infrastructure, and they do not have video detection on any traffic signals in Maple Ridge. The City only supplies the hydro power to the equipment. Currently, red light cameras are located at the intersections below:
- Lougheed Highway at Dewdney Trunk Road, for east bound traffic
- Lougheed Highway at 203 Street, for east bound traffic
- Lougheed Highway at 207 Street, for west bound traffic
Report any traffic signal issues for City-maintained lights to Public Works at 604-463-9581. Issues with the ones maintained by the Ministry of Transportation and Infrastructure can be reported to Mainroad Contracting at 604-271-0337.
