摘要
为了给研究者在选择人员疏散模型时提供参考。采用理论研究和模拟示例相结合的方法从移动方向和移动速度两方面对比Pathfinder软件和元胞自动机模型(CA模型)。Pathfinder移动方向选择范围较CA模型更广,但疏散目标单一;CA模型方向选择自由度低,但可考虑除出口吸引外的其他因素影响。Pathfinder较CA模型具有速度设定多样性优势。综合两点,Pathfinder对行人移动还原程度高,研究尺寸参数类因素的设置对疏散的影响时更为精确;CA模型移动规则设置灵活,在研究行人行为或新增影响因素时更为可行。
In order to provide a reference for the researchers in choosing the personnel evacuation model.Comparing the Pathfinder software and the cellular automata model(CA model) in terms of movement direction and movement speed. The Pathfinder movement direction selection range is wider than the CA model, but the evacuation target is single;The CA model direction selection freedom is low, but other factors except the export attraction can be considered. The Pathfinder has the diversity advantage of speed setting over the CA model. Based on two points, Pathfinder has a high degree of pedestrian movement, which is more accurate when studying the influence of size parameter factors on evacuation;CA model movement rules are flexible and more feasible when studying pedestrian behavior or new influencing factors.
