fotgängarsignaler

Fotgängarsignaler, eller fotgängarsignaler, are the traffic signals specifically designed to control pedestrian movement at intersections and crosswalks. They are typically mounted on pedestrian detection poles, crosswalk signals, or traffic lights and communicate whether pedestrians may safely cross the road. The signals usually employ a universal icon of a walking figure, though variations exist. Common forms include the walking signal, the cancelled walking figure or a red hand indicating pedestrians should wait, and increasingly the countdown timer that shows the remaining crossing time.

Pedestrian signals are governed by national or regional traffic code regulations. In Sweden, for instance, the Swedish Road Traffic Act specifies the placement, coloration, and operation of fotgängarsignaler. In many countries, the signals are integrated into the main traffic light circuit and are activated either by optional pedestrian detection sensors or by a button press. Automatic detection systems use passive infrared or other sensors to sense pedestrians standing or beginning to cross on a crosswalk, turning the signal on without human intervention.

Technological developments have expanded the functionality of fotgängarsignaler. Modern systems often include audible tones for visually impaired pedestrians, LED displays of countdown numbers, and touchscreen interfaces that provide timing information. Some cities have started experimenting with adaptive lighting, changing the intensity or hue of the signal elements according to traffic density and pedestrian volume. Integration with smartphone applications is also under exploration, enabling real-time updates and alerts.

The use of standardized pedestrian signals improves safety by providing clear communication between pedestrians and drivers. Studies have consistently shown that well-designed fotgängarsignaler reduce pedestrian crossing accidents, especially at busy intersections. Continued evolution of sensor technology, software integration, and inclusive design principles are expected to further enhance the effectiveness of these traffic control devices.
