What is the open loop block diagram of traffic light?

An open loop block diagram of a traffic light system typically includes a timer block, which controls the duration of each light phase (red, yellow, green), and an output block representing the traffic lights themselves. The timer operates independently of actual traffic conditions, simply cycling through the light phases based on preset intervals. There are no feedback mechanisms to adjust the timing based on real-time traffic flow or pedestrian activity. This system is straightforward and is primarily used in less complex traffic scenariOS.
