“…Tracker software provides a quantitative method for extracting the parameters such as instantaneous speed and instantaneous acceleration in the evacuation process of pedestrian from the collected social surveillance videos. In this paper, the used method is previously provided by other studies (Bernardini et al 2016;Zhou et al 2018aZhou et al , 2018b.…”

“…Moreover, many scientific studies are based on this intensity scale (He et al 2011a(He et al , 2011bWei et al 2013;Xu et al 2013;Wu et al 2015). In this paper, we use the CSIS as a measure of the seismic effects of the chosen earthquakes (Zhou et al 2018a(Zhou et al , 2018b.…”

“…The position of each student is noted in every time step from the moment they leave their seat. Thus, all students are traced until they reach the safety exit (Zhou et al 2018a(Zhou et al , 2018b.…”

“…The primary cause of earthquake-related casualties is that people fail to evacuate to safe areas before the buildings they occupy collapse. Thus, the correct and efficient earthquake emergency evacuation is closely related to human safety and survival (Zhou et al 2018a(Zhou et al , 2018b.…”

“…Yang has analyzed surveillance videos that record the evacuation of classroom students during the Wenchuan earthquake and found that the relation between the arrival time and the order in which students arrive is nonlinear (Yang et al 2011). Zhou has established a database on earthquake emergency evacuation (Zhou et al 2018a(Zhou et al , 2018b. Li has used the social force model to simulate and reproduce the escape panics of classroom evacuation in real-life 2013 Ya'an earthquake in China (Li et al 2015;Zhao et al 2017).…”

After earthquake, the correct and efficient earthquake emergency evacuation of pedestrian is crucial for reducing casualties. Based on the research on the quantitative of panic coefficient and the calibration of initial desired speed, this research has constructed the revised social force model which could accurately simulate the post-earthquake evacuation process of the crowed. Using the revised social force model, the effects of classroom layout, seismic intensity, the number of safeties exits and the number of students in the classroom on the evacuation efficiency are further studied. And then, according to the research results, the classroom layout has been further optimized to improve the students' earthquake emergency evacuation efficiency. These research results are scientific bases for the targeted earthquake emergency safety education and the design of classroom layout.
