Conference on Computer Applications in Civil and Hydraulic Engineering 2011 (CCACHE2011) September 01-02, 2011, Kaohsiung, Taiwan 4D動態模擬應用於災害疏散路徑規劃之研究 1 2 3 黃志翔 、吳翌禎 、夏冠群 摘要 發生建築物火災或重大車禍等人為災害，常因災後逃生或疏散動線不了解或指示不 明確，導致人員生命危害，為了減少災害發生時的傷亡程度，疏散路徑的選擇及規劃成 為重要的安全課題。本研究應用 3D視覺化環境及時間軸來模擬災害疏散路徑之規劃， 希望規畫者能在最短時間內進行緊急應變措施。本研究以一人為災害為例，考量災害各 種環境影響因子，透過 4D動態模擬，來呈現人車有效疏散路徑。本系統的 主要特色會 將疏散人車以分群方式疏散、不同疏散路徑之人車亦會以分色方式呈現，最後整體疏散 過程會隨時間一一展示。透過不同顏色來模擬呈現分群、分色、分時等系統特點，讓規 劃者瞭解每一疏散計畫的過程，再根據災害現況，選擇出最合適的疏散路徑，以降低災 害影響。 關鍵字 : 4D動態模擬、疏散、路徑規劃、人為災害 Applying 4D Simulation in Disaster Evacuation Route Planning 1 2 3 Chih-Hsiang Huang , I-Chen Wu and Kuan-Chun Hesia ABSTRACT This paper proposes a 4D simulation system to assist planners in planning disaster evacuation routes effectively and to visualize the plans over time. This research considered the various factors impacting upon the planning of an evacuation route to propose a numerical model for analyzing evacuation routes. Human behavior is another key consideration when planning disaster evacuation routes. For this reason, modeling of psychological variables to enhance prediction accuracy of human behavior during evacuations has been conducted in this research. In this system, the 3D objects in the urban model are highlighted in different colors, depending on their statuses of evacuation during simulation. In this way, a planner can find and utilize relevant and necessary data for planning evacuation routes in a more direct and efficient manner to mitigate the effects of the disaster.
