标题： Strategies in crowd and crowd structure

摘要： 在紧急情况下，模仿邻近行人的策略可能导致有序-无序相变，在这种情况下，行人会形成空间聚类并采用相同的策略。 我们假设存在两种策略：合作和竞争，分别对应较小或较大的期望速度。 我们的社会力模型模拟结果显示，可以通过观察人群内行人在空间位置上的秩序增加来检测出有序相。 显示英文摘要

摘要： In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy. We assume that there are two strategies, cooperating and competitive, which correspond to a smaller or larger desired velocity. The results of our simulations within the Social Force Model indicate that the ordered phase can be detected as an increase of spatial order of positions of the pedestrians in the crowd.
