A pedestrian signal is a traffic control device designed to help people safely cross streets. It typically features symbols or lights that indicate when it is safe for pedestrians to walk or when they should wait. Common signals include a green walking figure for "walk" and a red hand for "don't walk." These signals are often found at intersections and are part of a broader system that includes traffic lights for vehicles. They play a crucial role in ensuring the safety of pedestrians, especially in busy urban areas where foot traffic is high and vehicles are present, making them essential for urban planning and road safety.
