Crash Prevention & Safety > Pedestrian Safety


Pedestrian safety systems can help protect pedestrians by automatically activating in-pavement lighting to alert drivers as pedestrians enter crosswalks. Other systems include 'countdown' pedestrian traffic signals, and pedestrian detectors that extend the “Walk” phase for pedestrians needing more time to cross a street.
