Abstract

Accessibility between fire hydrants and buildings is paramount in emergency response, significantly influencing the efficiency and effectiveness of firefighting operations in the event of an incident. However, assessing this relationship within a geographic information system (GIS) framework presents challenges on two fronts. Obtaining the path avoiding building and parcel obstructions to hydrants is not trivial. Further, determining the furthest extent around a building exterior from hydrants is complicated, yet it is critically important given the spatial limitations of equipment reach. To assess furthest extent, an analytical framework is introduced based on the Euclidean shortest path problem. The proposed approach offers a comprehensive, automated GIS‐based methodology tailored to evaluate the dynamic relationship between hydrants and buildings. The developed methods are able to accurately and precisely identify the furthest point around a building structure from hydrant, facilitating risk assessment as well as fire code compliance. This enables a comprehensive evaluation of potential loss and structure vulnerability at property, street, neighborhood, and regional levels.

应急响应规划:评估水文-结构通道的框架
消防栓与建筑物之间的可达性在应急响应中至关重要,在发生事故时会极大地影响消防行动的效率和效果。然而,在地理信息系统(GIS)框架内评估这种关系面临两方面的挑战。要避开建筑物和地块对消防栓的阻碍,获取路径并非易事。此外,确定建筑物外部距离消防栓最远的范围也很复杂,但鉴于设备到达的空间限制,这一点至关重要。为了评估最远范围,我们引入了一个基于欧氏最短路径问题的分析框架。所提出的方法提供了一种基于 GIS 的综合自动化方法,专门用于评估消防栓与建筑物之间的动态关系。所开发的方法能够准确无误地识别建筑结构与消防栓之间的最远点,从而促进风险评估以及消防规范的合规性。这样就能在物业、街道、社区和区域层面对潜在损失和结构脆弱性进行全面评估。
