경로선택특성 분석을 통한 교차경로 통과시간 예측 모형 개발

Abstract

Recently, the buildings are the trend of enlargement and manhattanization. Particularly in case of multi-use facilities, it has the majority of maze structure and utilized for unspecified individuals who understand the space a little as their stakes are high to expose in fire and disaster. To prevent the fire and disaster, Republic of Korea implements Performance Based Design (PBD) but the simulation tool for required safe egress time analysis of PBD doesn't consider the way-finding characteristic though the junction routing selection or decision making time of occupants. Therefore, this paper organizes a mock-up set and analyzes human behavior characteristics of pedestrian targeting 70 people. The test was compartmentalized normal & smoke-filled condition and inquired into the behavior characteristics such as evacuation time, travel distance, walking speed though the experiment. Additionally, decision making time and characteristics of choosing the egress route in the junction were analyzed. Finally, based on the mock-up test results, suggest the junction-travel time prediction considering junction routing selection and decision making time of the pedestrian. Through this paper, the required safe egress time can be analyzed reflecting the decision making of pedestrian.
