Developing a database for pedestrians’ earthquake emergency evacuation in indoor scenarios

With the booming development of evacuation simulation software, developing an extensive database in indoor scenarios for evacuation models is imperative. In this paper, we conduct a qualitative and quantitative analysis of the collected videotapes and aim to provide a complete and unitary database of pedestrians' earthquake emergency response behaviors in indoor scenarios, including human-environment interactions. Using the qualitative analysis method, we extract keyword groups and keywords that code the response modes of pedestrians and construct a general decision flowchart using chronological organization. Using the quantitative analysis method, we analyze data on the delay time, evacuation speed, evacuation route and emergency exit choices. Furthermore, we study the effect of classroom layout on emergency evacuation. The database for indoor scenarios provides reliable input parameters and allows the construction of real and effective constraints for use in software and mathematical models. The database can also be used to validate the accuracy of evacuation models.

随着疏散模拟软件的蓬勃发展，构建覆盖室内场景的大规模疏散模型数据库已成为迫切需求。本文对采集得到的录像资料开展定性与定量分析，旨在构建一套完整统一的室内场景行人地震应急响应行为数据库，其中涵盖人-环境交互过程。通过定性分析方法，我们提取用于编码行人响应模式的关键词组与关键词，并按时间逻辑构建通用决策流程图。借助定量分析方法，我们对延迟时长、疏散速度、疏散路径以及应急出口选择等相关数据进行分析。此外，本文还探究了教室布局对人员应急疏散的影响。本室内场景数据库可为疏散模拟软件与数学模型提供可靠的输入参数，并可构建真实有效的约束条件。该数据库还可用于验证疏散模型的准确性。
