요약
단일 복도에서의 단방향 피난 이동 실험의 수행 결과, 평균 밀도 $2.36P/m^2$에서 0.55 m/s의 속도를 보이고 있다. S.F.P.E. Handbook에서 제시된 복도에서의 밀도기반 속도 수식 계산결과와 평균값을 비교할 때, 본 실험이 0.55 m/s, SFPE 수식이 0.53 m/s로서 0.02 m/s의 차이를 보였으며 데이터 별로 분석한 결과, 최대 0.38 m/s의 큰 차이를 나타내고 있다. 일부 실험결과는 보행속도의 증가에 따라 밀도가 높아짐을 보였으며 실험 결과분석은 전체 실험시간에 대한 평균 데이터를 사용하였다. 동영상에 대한 프레임단위 분석과 같은 세부적인 시간분석을 수행한다면 더욱 신뢰성 있는 데이터를 확보할 수 있을 것으로 보인다.
Abstract
In this study, the experimental measurements from a one-way moving experiment showed that the average movement speed was 0.55 m/s with an average crowd density of $2.36P/m^2$ in a corridor. The cCalculation result of the correlations between the crowd density and movement speed from the SFPE Handbook showed an average of 0.53 m/s. The difference between the calculation and experiment was 0.02 m/s. A comparison of each data set showed that the maximum difference was 0.38 m/s. Some experimental results showed that the crowd density increased with increasing movement speed and the average data from the entire experiment time was used for the analysis. When the short time interval for frame by frame analysis for video files was conducted, the experimental data was expected to be more reliable.
