“…We assume that the most reasonable catchment size for an emergency shelter can be identified as the point when the number of evacuees in the shelter catchment area matches the shelter capacity. Third, considering the differences between shelter and population catchments, we define the population catchment size as the walking distance from the population location to the second-nearest shelter [12,41]. Because McGrail, et al [46] pointed that the population would not access all the service facilities, using a fixed catchment size for demand population points will lead to measurement bias [36].…”

“…It is defined by utilizing a specific method to represent the systematic relationship between the points of departure and destination with the consideration for travel cost [8][9][10][11]. The spatial accessibility of urban emergency shelters can be utilized to measure the balance and equity between the shelter service and population demand [12].…”

As an important component of urban disaster prevention and mitigation systems, the balance and equity of emergency shelter distribution can be measured based on spatial accessibility utilizing the two-step floating catchment area (2SFCA) method. However, there are some issues in previous studies on emergency shelter accessibility evaluated by the 2SFCA method: (1) the high discretization of population distribution data and the travel cost being measured base on Euclidean distance; (2) ignoring the difference between shelter and population catchment sizes. To address these issues, we propose an improved 2SFCA method that computes the shelter and population catchments respectively to evaluate the emergency shelter accessibility in Changchun, China. We compare the proposed improved 2SFCA method to the original 2SFCA method. The results indicate that the catchment size and shelter accessibility calculated by the proposed method are more realistic and objective. The improved 2SFCA method is applicable method for evaluating the shelter accessibility and can provide advice for the planning and management of emergency shelters in the future.

“…There are a number of studies that investigate the pre-emergency strategies for the fire protection design (e.g., Mawhinney [9], Kironji [10], Mróz et al [11], Tomar and Khurana [12], and Rahardjo and Prihanton [13]) and the assembly point analysis (e.g., Raja Prasad and Prasad Rao [14], Unal and Uslu [15], Hoscan and Cetinyokus [16], and Şenik and Uzun [17]). For example, Kironji [10] assessed fire protection systems, such as the automatic sprinkler system, fire protection alarm, and escape route, for a commercial high-rise building.…”

Emergency events in the industrial sector have been increasingly reported during the past decade. However, studies that focus on emergency evacuation to improve industrial safety are still scarce. Existing evacuation-related studies also lack a perspective of fire assembly point’s analysis. In this research, location of assembly points is analyzed using the multi-criteria decision analysis (MCDA) technique based on the integrated information entropy weight (IEW) and techniques for order preference by similarity to ideal solution (TOPSIS) to support the fire evacuation plan. Next, we propose a novel simulation model that integrates fire dynamics simulation coupled with agent-based evacuation simulation to evaluate the impact of smoke and visibility from fire on evacuee behavior. Factors related to agent and building characteristics are examined for fire perception of evacuees, evacuees with physical disabilities, escape door width, fire location, and occupancy density. Then, the proposed model is applied to a case study of a home appliance factory in Chachoengsao, Thailand. Finally, results for the total evacuation time and the number of remaining occupants are statistically examined to suggest proper evacuation planning.

In the present study, the location-allocation and the accessibility models of GIS were integrated with the urban planning standards of the Ministry of Municipal and Rural affairs of Kingdom of Saudi Arabia (KSA) in order to enhance the spatial planning and the environmental sustainability of the green zones in Al-Dammam Metropolitan area, KSA. The integration of these models provides a framework for investigating the efficiency of the spatial distribution of the green zones and generating alternatives either by suggesting new effective service or by improving an existing one. To achieve these purposes, the accessibility within (5, 10 and 15) minutes to the service areas in the green zones that is classified into nine types (“neighborhood gardens”, “specialized parks”, “cities gardens”, “children’s gardens”, “district gardens”, “streets and squares gardens”, “sports city”, “Sports clubs” and “Playgrounds”) was analyzed through analyzing the network structure of the green zones in Al-Dammam Metropolitan area. The location-allocation model was used based on the maximum coverage within response time of no more than 10 minutes.The study revealed poor distribution of the green zones, the low per capita green zones rates with only (3.52 m2/person) and there were no green zones in 45 districts representing 33.3% of the total districts in the investigated area. Consequently, Al-Dammam Metropolitan area suffers from the weakness of the green zones structure and the shortage in fulfilling the needs of population. The current needs were determined as nine services by two “sports cities”, two “sports clubs”, two “streets and Squares gardens”, one “district garden”, one “children’s garden” and one “specialized park”.it is recommended that the results of this study be taken into consideration by the decision makers while developing the urban planning strategies for improving the infrastructure efficiency as the KSA vision 2030. Keywords: Urban planning; environmental sustainability; green zones; accessibility; location-allocation models; fair and efficient spatial distribution; KSA vision 2030.
