A study on quantitative risk assessment according to walking density

A study on quantitative risk assessment according to walking density

By Kyung-hoon Kim, et al.


The ultra-dense population concentration in a specific area was a result of human casualties caused by crushing accidents at home and abroad, such as the Itaewon disaster, and it is necessary to analyze the safety problem of the walking environment due to the concentration of the population. In this regard, various domestic and foreign studies are currently conducting research on improving pedestrian safety through data analysis and simulation by collecting pedestrian data in actual living facilities and living spaces. 

Therefore, in this study, using the FLEXSIM program for the alleys where the Itaewon disaster occurred, three alley cases (Basic, Narrow, Illegal) and three pedestrian control situations (two-way traffic, right-hand walking control, and one-way traffic control) were set. We analyzed the evacuation time and the number of collisions between pedestrians in the section according to the number of people evacuating the densely populated area. The data obtained through these simulations are expected to be used as basic data for quantitative risk assessment to prevent crush accidents and reduce casualties in the bottleneck section due to population concentration.
