Twotype Multiagent Game for Egress Congestion

Abstract

Our starting point is a recently introduced spatial multiagent game for egress congestion. We present a twotype extension of the game. In the game, the agent chooses its strategy by observing its neighbors’ strategies. The agent’s reward structure depends on its distance to the exit and available safe egress time (TASET ). Although TASET is a well-defined physical quantity, it is assumed that the agents interpret it subjectively: it is assumed that there are high TASET and low TASET agent types. Also, we apply the game to a cellular automaton (CA) evacuation model. We show that high TASET agents are on average able to overtake low TASET agents. However, the more there are high TASET agents in the crowd, the more the evacuation \ becomes inefficient for the whole crowd.
