Fixed signals are indicators that remain constant over time, providing reliable information in various contexts. In telecommunications, for example, fixed signals can refer to steady frequencies used for communication, ensuring that messages are transmitted without interruption. These signals are essential for maintaining clarity and consistency in data transmission. In the context of traffic management, fixed signals are traffic lights that operate on a set schedule, controlling the flow of vehicles and pedestrians. These signals help maintain order on the roads, reducing the risk of accidents and improving overall safety. By providing predictable cues, fixed signals enhance the efficiency of transportation systems.
