随着城市化进程加快,公共场所人员密集度和接触频次不断增加.在新型冠状病毒感染流行背景下,公共场所人员的健康安全问题凸显,如何有效管理公共场所已成为城市管理的难点.通过研究公共场所内人群疏导管控技术,可以有效疏导管控人群,减少人员拥堵,降低疫情传播风险,保障公众健康安全.首先,选定某大型体育场作为研究对象,参考相关标准和规范制订了大型体育赛事活动人员疏导管控方案;其次,构建公共场所人员疏导管控技术模型;最后,对不同类型的疏导管控方案进行三维模拟仿真.结果表明:通过不断更新迭代疏导管控方案,场内人员流通更通畅,新增患者比例由0.800%下降至0.075‰,从而验证了公共场所人群疏导管控方案可行和有效.
Crowd guidance and control technology for public places
[Objective]The accelerated process of urbanization and increased population mobility has led to a surge in population density and frequency in public spaces.This has underscored the importance of addressing health and safety concerns in public spaces,particularly considering the corona virus disease 2019(COVID-19)pandemic.The effective management of public spaces has become a challenging aspect of urban planning and management.Through research on management and control technologies for populations at high risk of exposure in public spaces,it is possible to achieve efficient management and develop control measures.This will lead to a reduction in overcrowding,lower the risk of epidemic transmission,and ultimately ensure public health and safety.[Methods]This research focuses on a gymnasium in Hangzhou,where the upcoming Asian Games will be held.The study focuses on developing time-based control measures,including time-sharing control measures,classification control measures,and classification and zoning guidance control measures,for large-scale sports events.These measures are developed based on relevant standards and norms.Furthermore,a technical model is constructed to assess personnel evacuation and control in public places,evaluate the level of crowd gathering in public areas,and simulate the number of infected people under various control measures.Thus,the effectiveness of evacuation and control measures is assessed through reverse verification.Finally,different evacuation control schemes are simulated using three-dimensional modeling using the MassMotion software.The technical model of evacuation control for public places is integrated into the MassMotion software development kit(SDK),which is the software's secondary development system.This integration allows for the output of individual density proportion diagrams and COVID-19 virus transmission results under different evacuation control schemes.[Results]The simulation results showed that continuous updates to the guidance and control scheme improved the flow of people in the venue and decreased emergency evacuation time.Moreover,increasing social distance significantly reduced the risk of crowd aggregation and infection.These findings provided evidence supporting the feasibility and effectiveness of the guidance and control scheme for high-risk exposed individuals in public settings.[Conclusions]This study proposes a crowd guidance and control technology for public places aimed at ensuring public safety amidst the COVID-19 pandemic.This research conducted on a gymnasium as a case study provides insights into personnel circulation and COVID-19 transmission under different diversion and control schemes.Further,the research offers valuable support for the implementation of crowd diversion and control measures during large-scale sports events,ensuring the safety of attendees and the broader public.
