지하공간은 화재를 비롯한 재난이 발생했을 때 지상공간에 비해 더 큰 위험이 따르므로 비상유도등 설계시에 공간의 특징을 충분히 고려해야 한다. 공간구문론의 뎁쓰맵(Depthmap) 프로그램은 공간의 정량적인 분석을 가능하게 하는 프로그램으로, 이를 통해 개구부의 위치 등 평면 구성에 따른 공간의 정확한 분석을 할 수 있다. 본 연구에서는 공간구문론을 이용한 지하공간 비상유도등의 위치선정 방법론을 검토하기 위해 화재발생시 나타나는 인간 행동의 특징을 파악하고 복잡한 공간에서 생존자득의 피난경로를 선택하는 방법을 분석하였다. 그리고 공간구문론으로 분석된 특정 공간에 이상의 분석결과를 종합하여 천편일률적인 설치가 아닌, 공간의 구조를 고려한 비상유도등의 효율적인 위치선정 방법론을 검토하였다.

The emergency lighting plan for underground space should be done with consideration of characteristics of the space. Through the Space Syntax theory, it is possible to do quantitative analysis of the space. Integration and intelligibility are major index of this theory and we can use them as emergency lighting design parameters. For this study, human behaviors and survivor's evacuation routes in fire emergencies are analyzed through literature review. Based on those results, this study suggests the methodology of emergency lighting plan in underground space.

In this paper, we present Emergency exit signs are installed to provide escape routes or ways in buildings like shopping malls, hospitals, industry, and government complex, etc. and various other places for safety purpose to aid people to escape easily during emergency situations. In case of an emergency situation like smoke, fire, bad lightings and crowded stamped condition at emergency situations, it's difficult for people to recognize the emergency exit signs and emergency doors to exit from the emergency building areas. This paper propose an automatic emergency exit sing recognition to find exit direction using a smart device. The proposed approach aims to develop an computer vision based smart phone application to detect emergency exit signs using the smart device camera and guide the direction to escape in the visible and audible output format. In this research, a CAMShift object tracking approach is used to detect the emergency exit sign and the direction information extracted using template matching method. The direction information of the exit sign is stored in a text format and then using text-to-speech the text synthesized to audible acoustic signal. The synthesized acoustic signal render on smart device speaker as an escape guide information to the user. This research result is analyzed and concluded from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinder system.
