Crosswalk signals are traffic control devices that help pedestrians safely cross streets. They typically include a combination of visual and audible signals, indicating when it is safe to walk or when to wait. The signals often feature a walking person symbol for "walk" and a raised hand for "don't walk." These signals are usually placed at intersections and are designed to improve pedestrian safety by coordinating the flow of foot and vehicle traffic. In many cities, traffic lights and road signs work in conjunction with crosswalk signals to enhance overall road safety for both pedestrians and drivers.
