摘要
为探究局部聚集效应对景区密集人群流动规律的影响,基于实地调研数据,运用Pathfinder软件构建景区人群流动模型,综合考虑打卡点空间布局、游客群组比例及人流率等因素,围绕网红打卡点引发的局部聚集效应,开展不同情景模拟实验并进行对比分析。研究结果表明:打卡点吸引度的提升显著降低行人流动效率,当吸引度达到100%时,打卡区域行人整体速度下降73.9%;单一打卡点布局靠近景区出口有助于提升整体人群流动速度,而2个打卡点采用间隔式布局比连续分布更有利于人群疏散,堵塞时间减少21%;在恒定输入人流量条件下,群组占比越高,滞留时间越长,且受打卡点吸引时行人流动路径更为复杂。研究结果可为网红打卡地等高密度人群聚集场所的空间布局优化及安全管理提供借鉴和参考。
In order to explore the influence of local aggregation effect on the law of dense crowd flow in scenic spots,based on the field survey data,a crowd flow model of scenic spots was built by using the Pathfinder software.Comprehensively considering the spatial layout of popular check-in spots,the proportion of tourist groups and the pedestrian flow rate,different scenario simulation experiments were carried out and comparatively analyzed around the local aggregation effect caused by popular check-in spots.The results show that the increase in the attractiveness of popular check-in spots significantly reduces the pedestrian flow efficiency.When the attractiveness reaches 100%,the overall speed of pedestrian in the popular check-in spots areas decreases by 73.9%.The layout of a single popular check-in spot near the exit of scenic spot is helpful to improve the overall crowd flow speed,while the spaced layout of two popular check-in spots is more conducive to crowd evacuation than the continuous distribution,and the congestion time is reduced by 21%.Under the condition of constant input pedestrian flow,the higher the proportion of groups,the longer the detention time,and the more complicated the pedestrian flow path when attracted by popular check-in spots.The research results can provide reference for the spatial layout optimization and safety management of high-density crowd gathering places such as the popular check-in spots.
