智能交通灯如何根据实时车流调整红绿灯时长

Cameras and embedded road sensors detect vehicle count, speed, and direction every five seconds.
When more cars approach from the north, the light extends green time for that lane automatically.
Buses and emergency vehicles trigger priority signals if equipped with transit beacon transmitters.
During school drop-off hours, nearby intersections coordinate to create smoother traffic waves.
The system lowers red-light duration when no vehicles wait, cutting idle time by up to 40%.
City engineers monitor performance dashboards but rarely intervene unless anomalies appear.
Pedestrian crossing buttons now link to light timing, giving safe gaps even during heavy flow.
Weather data adjusts response logic—snowy conditions slow transitions for safety.
You’ll notice fewer sudden stops and longer green stretches during weekday commutes.
Each intersection stores local traffic habits to improve predictions overnight.
