What is AutoGreen?
AutoGreen is an advanced form of smart radar-based Vehicle Actuation (VA) for portable and temporary traffic signals, designed to dynamically adjust signal control to create a safer, greener and more efficient roadworks environment.
AutoGreen achieves this through a series of traffic scenarios, where signal performance is optimised according to current traffic conditions. This enables portable signals to incrementally adapt to an ever-changing traffic environment.
Traditional VA systems for portable signals use simple Doppler radars as the detection input for the signals. Doppler radars only detect movement and cannot detect gaps or identify vehicles, therefore cannot react in the same way as AutoGreen. Often VA systems are set up with high green times, increasing the risk of the shuttle lane becoming blocked, creating severe congestion from which it cannot recover without manual intervention – AutoGreen is only system that can detect when a site is congested and gives every phase guaranteed green time, replacing the need for manual control in many cases.
AutoGreen Technology is powered by an industry-leading FMCW radar, offering improved detection, higher data accuracy and low power consumption. Our FMCW radar is not susceptible to non-vehicle targets, weather or other common issues associated with Doppler radars.
AutoGreen Technology has been proven to improve journey times by up to 50%, and is exclusively found on Pike Signals and Hollco products from Traffic Group Signals.
