本計畫研究之主題為「大規模地下空間避難弱者之情境模擬及避難疏散策略」藉由相關研究報告與文獻資料得知，一般民眾處於「大規模」或「地下空間」之建築型態下，當災害發生時人員逃生避難已經相當不易；當不幸發生火災對於水平移動都覺得困難之「避難弱者」，卻必須同時面對大規模空間及必須藉由垂直避難動線，才得以成功逃生至地面避難層或相對安全避難據點，其危險程度不言可喻。因此，如何設身處地模擬大規模地下空間發生火災之危險情境，並藉由危害「避難弱者」之危險情境模擬，訂定有效避難或疏散策略，藉以提高其逃生避難成功之機率，即為本計畫主要研究方向。
"The simulating situation and the escaping strategy for disabilities in the huge underground space" is the point of this project. Learning from relevant research, people in the building type of "huge" or "underground space" is difficult to escape, when the fire happened, especially for the disabilities. Moving horizontally to the disabilities is not easy, but they have to move vertically to escape when the fire take place in the huge and underground space. The disaster can't be imagining. Therefore, how to simulate the fire is happened situation in the huge and underground space, and how to simulate the disabilities escaping situation, and meanwhile, to stipulate the strategy for escaping dispersion, to improve the probability of escaping successfully, are main directions for this research.
