This elevated level of violence persisted for several months after the aid suspension.

The Unconscious Influence of Train Station Walking Patterns

Research has revealed a compelling, often unconscious, behavioral tendency among individuals exiting train stations. People frequently adopt the walking path of the person directly ahead of them, even when they are unfamiliar with that individual and when doing so potentially increases their travel time. This suggests a strong influence of social cues on individual movement.
