Abstract

Abstract: In order to effectively prevent subway crowding and stampede accidents, data on the recent subway stampede accidents were analyzed, areas vulnerable to crowding and stampede accidents were identified, and the inoculation, evolution and development stages of the stampede accident in subways were revealed. Effects of crowd wave, distortion of information transmission, and hedging caused by spatial obstruction were analyzed among others. A stage critical for preventing and controlling subway crowding and stampede accidents was identified. An intelligent warning system was developed for subway crowded trampling accidents. The research results show that the inoculation stage is critical for preventing and controlling the accidents, that the intelligent warning monitoring system can assess the warning level, show the risk level corresponding to a given people's status or density, and is helpful in controlling subway crowded stampede accidents.

Key words: subway, crowded stampede accident, vulnerable areas, intelligent warning system, emergency evacuation
