Abstract
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.
Highlights
We summarize the general characteristics and conditions experienced by the selected more than one hundred individuals, seismic intensity according to the Chinese seismic intensity scale (CSIS) (Fig 1), social context (Fig 2), the year in which the earthquakes occurred (Fig 3), the specific earthquake (Fig 4), and gender (Fig 5)
Models used in the study of earthquake emergency responses represent a complex nonlinear physical problem [37]
Quantifying the emergency response behavior (EERB) of pedestrians during an earthquake emergency is of the utmost importance when developing models
Summary
It is among the countries that have suffered the most from a serious earthquake. The 2014 Ms 6.4 Ludian earthquake caused 617 deaths and injured 3,143 people, and 112 people went missing (as of 3 p.m. on August 8th); the 2014 Ms 6.6 Jinggu earthquake caused 1 death and injured 323 people (as of 4 a.m. on October 8th); the 2013 Ms 6.6 Zhangxian earthquake caused 89 deaths and injured 628 people, and 5 people went missing (as of 8 p.m. on July 22nd); and the 2013 Ms 7.0 Lushan earthquake caused 196 deaths and injured 11,470 people, and 21 people went missing (as of 2 p.m. on April 24th) (China Earthquake Administration: http://www.cea.gov.cn/).
