Abstract: With the diversification of transportation, the emergencies encountered by travelers during travel are becoming increasingly complex. The narrow aisle space within aircraft cabins, due to layout limitations, significantly restricts evacuation behavior, thereby escalating the complexity of evacuation procedures. This work studies the impact of common emergency-limiting factors such as obstacle types, initial movement speeds, aisle widths, and movement modes on personnel avoidance behavior within aircraft cabins. Research has found that the presence of suitcase obstacle primarily influenced the choice of avoidance behavior through subjective factors such as movement mode and initial speed. Conversely, in scenarios with pedestrian obstacles, avoidance behavior is shaped by both subjective factors and the evacuation environment (aisle width, obstacle type). Regarding movement trajectory, the lateral movement range of pedestrians is mainly related to the width of the aisle. At the same time, the lateral deviation of pedestrian movement trajectory will be adjusted according to the movement mode and obstacle type, and the safe distance for pedestrians to avoid the obstacles is approximately 0.5 m–1.5 m. In addition, research has found that in a 0.4m wide and obstacle-free aisle, the need for "obstacle-free" evacuation has been met, and the speed no longer increases with the width of the aisle. The aisle width is the main factor affecting the distribution of the average movement speed range. When there is suitcase obstacle, the frequency distribution of pedestrians' movement speed is related to their movement mode. The low-speed frequency of the "individual" is significantly higher than that of the "group".
