How to report issues with or request the installation of traffic signals

If you come across:

• Traffic Signals not working
• Traffic Signals out of sequence
• Traffic Signals knocked down

or

• to request traffic signals to be installed:

please contact Customer Services

Pedestrian Crossing

Red - Do not cross

Amber - If started continue otherwise do not cross

Green - Invitation to cross

Pedestrian Crossing Detector

What Are They?

A pedestrian detector is a sensor that detects that a pedestrian is standing and waiting at the pedestrian crossing after they have pushed the pedestrian crossing button.

This helps the traffic signal controller operate more efficiently by ignoring pedestrian crossing demands after the pedestrian has moved on.

How Do They Work?

After a pedestrian has pushed the push button to call for a pedestrian crossing, the pedestrian detector ensures there is still a demand for a pedestrian crossing; by using a radar to observe whether pedestrians remain in the crossing wait zone.

The wait zone is typically the red blister tactile paving at the pedestrian crossing along the kerb.

The detector is designed to be sensitive to the presence of pedestrians within the detection zone (Active). 

If a pedestrian presses the push button and then proceeds to cross the road or moves on before the pedestrian crossing signal, the pedestrian detector tells the traffic signal controller that the pedestrian is no longer there.

This allows the controller to decide to cancel the pedestrian crossing phase of the cycle, allowing the junction to operate more efficiently.

Traffic Detector

What Are They?

You may have wondered what the black markings near traffic signals are; Traffic detectors also know as ‘’Induction loops’’  are sensors made up of copper or aluminium. They are usually embedded in the roads surface near a traffic signal and are used to detect the presence of traffic. 

How They Work?

When a vehicle drives onto the traffic detector the metal from the vehicle triggers the sensor. This notifies the traffic controller that traffic is present at the junction.

NOTE : Not only is it illegal to move past the stop-line on a red signal, but your car will also not be on the detector; meaning the traffic controller will not know you are there.

Right Turn Box 

If a right turn box is in a junction, the vehicle must enter it to activate the filter signal.
