When an emergency situation happens in buildings, the top priority is to ensure the occupant from danger as soon as possible. Achieving that goal is a multifaceted and difficult task. However, current evacuation systems have many deficiencies in dealing with the emergency in multi-level structures. The shortage of abilities to continuously update database, predict the future situation and provide the information to users with contextual information is the limit in current systems. Thus, it is very crucial to introduce Evacuation Information System (EIS), which is able to respond quickly to the emergency, and transfer the information to both the administrator and the occupant. The main purpose of this paper is to build EIS on the basis of the indoor Geographical Information System (GIS). When the emergency happens, EIS gives the instruction to Emergency Response Model (ERM) at once. ERM carries out the order and calculates the optimal evacuation routes, then sends the result to EIS. At last, EIS transmits evacuation messages to the occupant who implements evacuation plan. This paper highlights the benefits of EIS in two aspects. One is that EIS can update the data continuously to support evacuation strategy-making. The other is that it can transmit evacuation messages to both the administrator and the occupant.

Rising urban flood patterns are a universal phenomenon and a significant challenge for city government and urban planners worldwide. Urban flood problems range from relatively localized incidents to substantial incidents, which lead to cities being flooded for a few hours to several days. Therefore, the effect may be widespread, such as the temporary displacement of individuals, disruption to civic facilities, water quality degradation and the possibility of epidemics. The problems raised by urban flooding are highly challengeable and compound by ongoing climate change, with adverse implications for changes in rainfall and gaps in intra-urban rainfall distribution. Unplanned construction and invasions of large houses along rivers and watercourses have interfered in natural rivers and watercourses. As a result, the runoff has risen in proportion to the urbanization of the urban floods. The location of the relief camp and the priority for evacuation were determined, and the safest route to avoid floods were established. This method can be used for emergency planning in future flood incidents, and it will help plan disaster preparedness for Panchayat. This study will promote the flood plain's potential use for disaster management and land use planning virtually.

The purpose of this paper is to provide a suggestion regarding how to make systematically improve the evacuation facilities of the cinema which is a large indoor space and utilizing by a numerous people. For the first, as a method of study, an analyzed on researching documentary recorders which are concerned with building codes regarding the evacuation facilities of cinema is made, and Secondary, carried out a survey of questionnaire for finding what the most audiences' idea regarding evacuation facilities of the cinema while they are utilizing the facilities, and analyzed the information. In the focus of the users, the result of analyzation reveals that as the item of practical facilities such as width and number of exit ways from viewer seats, width of corridors are highly suggested to improve practical system.

Recently, Korea is constantly increasing its elderly care hospitals, and requires establishment of general evacuation plan considering old people's behavioral characteristics and physical states in emergency situations such as fire, and etc. In addition, because most of the facility users are patients under serious dementia and stroke, they feel difficulty evacuating by themselves, with differing evacuation time according to each walking status (bed, wheel chair, and various supplementary instruments), which is why it makes it difficult to have them all evacuate. This paper, in order to suggest data reference for designing on the basis of functionality, used various collected data utilizing Simulex to measure evacuation time through the model of elderly care hospital, a medical facility. During the study, several problems were found.

This paper analyzed a survey of 388 general target samples to analyze the correlation between disaster safety costs and human risk factor analysis and evacuation behavior due to tunnel accidents. Considering the impact of the tunnel accident on disaster safety costs and the correlation between human evacuation and risk factors in the tunnel environment, the system should be reorganized to reflect the tunnel's basic plan, tunnel cross-section, tunnel installation.

Nowadays, the most of commercial buildings are build-out with complex architecture and decorated with more complicated interiors of buildings so establishing intelligible escape routes becomes an important case of fire or other emergency in a limited time. The commercial buildings are already equipped with multiple exit signs and these exit signs may create confusion and leads the people into different directions under emergency. This can jeopardize the emergency situation into a chaotic state, especially in a complex layout buildings. There are many research focused on implementing different approached to improve the exit sign system with better visual navigating effects, such as the use of laser beams, the combination of audio and video cues, etc. However the digital signage system based emergency exit sign management is one of the best solution to guide people under emergency situations to escape. This research paper, propose an intelligent evacuation route GUIDE that uses the combination centralized Wireless Sensor Networks (WSN) and digital signage for people safety and avoids dangers from emergency conditions. This proposed system applies WSN to detect the environment condition in the building and uses an evacuation algorithm to estimate the safe route to escape using the sensor information and then activates the signage system to display the safe evacuation route instruction GUIDE according to the location the signage system is installed. This paper presented the prototype of the proposed signage system and execution time to find the route with future research directions. The proposed system provides a natural intelligent evacuation route interface for self or remote operation in facility management to efficiently GUIDE people to the safe exit under emergency conditions.

This study explored the fact that libraries can be used as evacuation facilities, suggesting that existing libraries built not only strengthen their role and function as evacuation facilities but also need to be constructed or remodeled to meet the criteria for designation and operation of evacuation facilities. The use of closed schools was proposed to pursue economic efficiency and regional effects in building or remodeling, and the status of the evacuation facilities and closed school in Chungju was evaluated to check the effectiveness of these proposals, and closed school was assessed based on the capacity of the shelter. The three main points of discussion in this paper are as follows: ① Reconfirm what functions and roles the library are performing as an evacuation facility, and explore the advantages of using the library as an evacuation facility is used as an evacuation facility. ② Review and discuss the synergy by the role of the library and the closed schools. ③ Examine and discuss the synergy between these roles of the library and the closed school.

A total of 19 elevators for evacuation were installed in the Lotte World Tower and it is planned to operate the shuttle using the manual key from five refuge floors to the 1st floor in an emergency. In the event of a fire or other disaster, it is necessary to conduct intensive analysis to determine how much RSET reduction could be achieved using the evacuation elevator compared to the existing evacuation plans. When the optimal transportation sharing ratio by the evacuation elevators was 40% at the Lotte World Tower, the RSET of the evacuation scenario in parallel with the elevators in the entire building was calculated to be 1 hour and 2 minutes. The RSET of a conventional evacuation scenario (Walking along the stairs without using the elevators) was calculated to be 1 hour 29 minutes, therefore, the former evacuation scenario were found to have a shortening effect of approximately 27 minutes compared to the latter. On the other hand, to maintain this effect, each part of the evacuation route using the elevator must have the capability to protect the evacuee from any hazards caused by fires, such as smoke, flame, and radiant heat during the evacuation. Moreover, the evacuation route should be continuous from the residence position of the elevator user to the final evacuation site, and be recognized easily.
