Adaptive Crowd Control using Promotion Signage to Promote Smooth Evacuation

Crowd control is one of the ways to prevent unexpected events at places where a large number of people gather. With technology developments, new evacuation systems are proposed in prevention planning. Recently, digital promotion signage has been used recently for promotion and advertising in public and commercial spheres. It is pointed that digital promotion signage attracts more attention than the traditional emergency-exit sign and the effect of the digital promotion signage to control human evacuation flow is verified by simulations. In this paper, we discuss a method that changes the contents of signage adaptively to the situations of congestion. This idea provides one solution for situations that many people are caught in the congestions and applying the idea to new application fields is also discussed.
