In recent years, interest in fires involving a number of casualties has increased, and the death toll ratio was 14% of all casualties in Seoul from 2009 to 2014, while the disabled accounted for 57% and about four times more people with disabilities died of fires than ordinary people. In addition, the major fires in the 2016 fire statistics analysis show that 203 cases (58%) of the fires occurred at the school, followed by other 78 cases (22%), 39 cases public offices (11%), and 22 cases public building (6%), and the this statistics results indirectly suggested that the most fires among the major fires except general fires are more susceptible to fires for students with disabilities than non-general students. Therefore, this study classifies the factors affecting the walking speed of students with disabilities of the significance of these walking speeds on the dependent factors is examined through correlation analysis, T-test, and ANOVA analysis. The importance and correlation of the factors between factors affecting walking speed are analyzed through statistical analysis. And based on this, the walking speed of students with disabilities is grouped and the evacuation completion times are analyzed with by Pathfinder simulation. Finally the basic data for evaluation evacuation stability in case of fire of students with disabilities is provided.
