A barrier works as the signal because it provides a clear, physical stop to pedestrians. When a barrier is across a crossing, it communicates immediately and unambiguously that crossing is not allowed at that moment, which is crucial for safety in busy or hazardous situations. Hand gestures or signals from a person directing traffic rely on visibility and interpretation, but a barrier physically blocks the path and cannot be ignored, making it the most definite way to stop pedestrians crossing.
