【摘要】：为了向步行设施内的疏散行人流提供合理的物理空间布局,研究行人步行设施空间的疏散特征指标.首先,根据步行设施内部空间是否能被行人占据移动,将其划分为行人移动空间与障碍物空间,并利用障碍物空间外缘轮廓线间的最短距离确定行人移动的瓶颈宽度;然后,基于移动瓶颈对行人移动空间的毗邻划分,提出了步行设施行人疏散的移动网络构建方法,将步行设施空间转化为行人疏散的移动网络;基于行人移动距离最短的疏散路径选择策略,将移动网络转化为疏散树;最后,基于疏散树的层和节点及其隶属关系,从空间面积、移动距离、瓶颈宽度、障碍物布局4个角度提出了步行设施空间的疏散特征指标.进而得到评价步行设施空间布局及调整优化障碍物布局的方法,算例分析表明:根据指标对障碍物的布局进行调整,优化了障碍物布局,证明指标在步行设施空间疏散特征分析中的可应用性及有效性.
[Abstract]:In order to provide a reasonable physical space layout for pedestrian evacuation in pedestrian facilities, the evacuation characteristics of pedestrian walking facilities are studied. Firstly, according to whether the inner space of walking facilities can be occupied and moved by pedestrians, it is divided into pedestrian moving space and obstacle space, and the bottleneck width of pedestrian movement is determined by using the shortest distance between the contour lines of the outer edge of obstacle space. Based on the adjacent partition of pedestrian moving space by moving bottleneck, this paper puts forward a method of constructing pedestrian evacuation mobile network, which converts walking facility space into pedestrian evacuation mobile network. Based on the evacuation path selection strategy of the shortest pedestrian distance, the mobile network is transformed into an evacuation tree. Finally, based on the layer and node of the evacuation tree and its membership relationship, from the space area, moving distance, bottleneck width, The evacuation characteristic index of walking facility space is put forward from 4 angles of obstacle layout. Then the method of evaluating the space layout of walking facilities and adjusting the layout of obstacles is obtained. The example analysis shows that the layout of obstacles is adjusted according to the index, and the layout of obstacles is optimized. To prove the applicability and effectiveness of the index in the analysis of space evacuation characteristics of walking facilities.
