Abstract: In the rescue simulation， the effects of police clear roads have a vital role in the whole disaster. According to how the police agent clear roads， this paper proposes a police agent’s task allocation method based on the utility function， and a kind of path searching method based on A* algorithm. Then， the effectiveness of control methods in the rescue simulation system through simulation and competition is verified.
