Wing gate turnstiles are widely used in airports, subway stations, railway stations, movie theaters, parks, etc., and influence the pedestrian evacuation greatly while accidents happen. Thus, doing some researches on how to improve the evacuation speed for wing gate turnstiles are meaningful and necessary. In response to this issue, the influences of the wing gate turnstiles on pedestrian evacuation are investigated by pathfinder in this paper. Pathfinder is an agent-based egress simulator that uses steering behaviors to model occupant motion. First of all, by Pathfinder, two evacuation models with flat-shaped and wedge-shaped hosts wing gate turnstiles, respectively, are established, and the simulations of pedestrian evacuation are carried out by computer. The results show the evacuation speed obtained by the wedge-shaped host is faster than that obtained by the flat-shaped host. Moreover, the longest evacuation time is obtained when the channels' width is 90 cm, and the shortest is obtained when the channels' width is 51.4 cm. For a small number of evacuees, the evacuation time is mainly influenced by the original distributions of the evacuees, however, as the number of the evacuees increases, the evacuation time is mainly influenced by the number of the evacuees. Furthermore, the wing gate turnstiles with widened hosts can get less evacuation time no matter whether the hosts are flat-shaped or wedge-shaped, however, the evacuation-time-saved rate obtained by wedge-shaped host is much higher than that obtained by flat-shaped host. Then, the influences of the wedge angle on the pedestrian evacuation are discussed, and the optimal wedge angle is obtained. The obtained results can not only provide helps for managers to evacuate crowds under emergency, but also offer some assistances for designers to design those gate turnstiles or building exits.
翼闸转门广泛应用于机场、地铁站、火车站、电影院、公园等场所，在发生事故时对人员疏散影响较大。因此，研究如何提高翼闸转门的疏散速度具有重要意义。针对这一问题，本文采用基于主体的人员疏散模拟软件 Pathfinder 研究了翼闸转门对人员疏散的影响。Pathfinder 是一种基于主体的人员疏散模拟软件，使用转向行为来模拟人员的运动。首先，通过 Pathfinder 建立了具有平板式和楔形主机翼闸转门的两种疏散模型，并通过计算机对人员疏散进行了模拟。结果表明，楔形主机的疏散速度比平板式主机快。此外，当通道宽度为 90cm 时，最长疏散时间，当通道宽度为 51.4cm 时，最短疏散时间。对于少量的疏散人员，疏散时间主要受疏散人员的原始分布影响，但是，随着疏散人员数量的增加，疏散时间主要受疏散人员数量的影响。此外，无论主机是平板式还是楔形，加宽主机的翼闸转门都可以获得更少的疏散时间，但是，楔形主机获得的疏散时间节省率远高于平板式主机。然后，讨论了楔形角对人员疏散的影响，并得出了最佳楔形角。所得结果不仅可以为管理人员在紧急情况下疏散人群提供帮助，还可以为设计者设计这些闸机或建筑物出口提供帮助。
