摘　　要：为实现行人在紧急疏散过程中随时随处获取连贯的疏散标志指示信息,基于等边三角形划分空间平面的几何特征、疏散标志信息的服务半径和服务率,提出无障碍物设施"相切圆填充"的设置方法;基于行人疏散距离和疏散路径簇,提出存在障碍物设施"簇节点布局"的设置方法;基于元胞自动机空间划分理念和最短路搜索算法,计算和标定步行设施内的疏散路径簇及其簇节点.结合案例分析,阐述了大型行人步行设施内紧急疏散标志设置方法的一般步骤.The location method of emergency evacuation signs in large pedestrian facilities was presented, in order to ensure the spatial and temporal continuity of signs indication in pedestrian emergency evacuation. Considering the geometry characteristics of regular triangle, the radius and ratio of signs service, the distance of pedestrian evacuation and the chain cluster of evacuation route, two methods of ＂filling with tangent-circles＂ and ＂ setting at hinge node＂ were introduced to locate evacuation signs respectively in no-obstacle and existing-obstacle pedestrian facilities. The computation of the chain cluster of evacuation route and the labeling of hinge node in pedestrian facilities were carried out based on the partitioning of cellular automaton and the shorter path search. Through two cases, the procedure of the location of emergency evacuation signs was presented in pedestrian facilities with and without evacuation obstacles.
