TRACER OBSERVATION OF EGRESS AND WAY HOME CROWD BEHAVIOR AT STADIUMS FROM THE PERSPECTIVE OF CROWD CONTROL IN EMERGENCY EVACUATION

Abstract

Crowd control method at stadiums in emergency evacuation situation such as a fire, bomb threat, and terror is discussed. For its basis, egress and way home crowd behavior in eight stadiums was observed through walking with the crowd and mixed in like a tracer. In some stadiums, the crowd was controlled by closing some exits, temporary fences, and stewards’ guidance to relieve congestion outside the stadium site. In contrast, some stadiums let pedestrians walk freely; however, no accumulation was generated. The latter strategy is desirable for emergency evacuation, and its architectural design consideration and guidance policy are discussed.
