Traffic signals are core infrastructure for traffic management. Through the switching of red, yellow, and green lights (with customizable switching cycles), they direct the orderly passage of motor vehicles, non-motorized vehicles, and pedestrians, effectively preventing traffic chaos and accidents. On urban main roads and intersections, traffic lights ensure efficient road operation; on special sections of highways (such as tunnels, bridges, and construction zones), traffic lights prompt vehicles to slow down or change lanes (response time ≤ 0.5 seconds), ensuring driving safety in complex road conditions. Around public places such as schools and hospitals, traffic lights (with optimized timing algorithms) guide pedestrian and vehicle flow, reducing congestion; after the widespread adoption of traffic lights on rural roads, the order of mixed traffic flow has significantly improved (accident rate reduced by 30%+). When linked with intelligent transportation systems, traffic lights can adjust timing in real time (traffic flow detection accuracy ≥ 95%), dynamically improving traffic efficiency.
Urban road traffic lights: Used at intersections of various roads within cities, this is the primary application scenario for traffic lights. Urban road traffic lights need intelligent adjustment based on factors such as vehicle and pedestrian flow.
Highway traffic lights: Primarily used at highway toll booths, service area entrances, and other areas to control vehicle entry, exit, and speed. Highway traffic lights typically use larger sizes and higher brightness to ensure long-distance visibility.
Railway and highway intersection traffic lights: Installed at level crossings between railways and highways to indicate when it is safe for vehicles and pedestrians to cross. These lights need to be linked with the railway signaling system to ensure safety.
Special scenario traffic lights: Such as traffic lights in school zones and construction zones, designed according to the specific needs of the scenario, with stronger targeting and warning functions.
