The QTech WP2P low power radio system has been chosen for an emergency services traffic light override project.
Modern traffic light control systems use a sophisticated electronic controller to help meet the complex requirements of traffic authorities.
These traffic light controllers have multiple external inputs to enable special configurations for railway crossings, pedestrian requests, automated cycle lanes and emergency vehicle overrides.
In this project, the requirement was for the driver of the emergency response vehicle to press a button as they leave the station. This button press is to override the current traffic light sequences, giving the emergency vehicle green traffic lights.
This button operates one of the inputs on the WP2P module and also opens the garage door.
At the traffic controller, the output of the second WP2P module is wired to the controller. When activated, the controller overrides all the nearby traffic lights and performs the required interlocking. This ensures that emergency vehicles have green traffic lights and right of way through all the local traffic signals. This helps to safely speed up their response time and gives the other road users a clear signal.
The WP2P low power radio system has a range of several kilometres with optional antenna systems. It can be used in many other applications such as irrigation and pump control, flow meter pulse transmitting or flood detection systems.
Solar powered options are also available for applications where a 12-24V DC supply is not available.
