How Do Locals Know Which Exit to Use Before Leaving a Train Station?
Experienced travelers navigate destinations, not stations.
Visitors often see station exits as equivalent. Locals rarely do.
The hidden mechanism is destination optimization. Frequent commuters choose exits based on what happens after they leave the station rather than what happens inside it.
Imagine a station with six exits. One leads directly to office towers, another to bus connections, and another to a shopping district. Experienced commuters begin making exit decisions before the train even stops.
A second-order effect appears as commuters repeatedly use the same exits. New passengers observe these patterns and interpret them as signals, reinforcing traffic flows over time.
People often think locals know the station better. In reality, they know the city beyond the station better.
