都市過度發展，成為人口及經濟高度聚集的區域，若發生重大災害，都市中人的生 命及財物損失將十分嚴重。都市中之舊市區發展較早，都市規劃缺乏妥善的避難逃生觀 念，並且區内人口稠密、建築物結構老舊、道路狹窄及公共避難空間不足等。一旦災害 如重大火災或地震發生，將會造成極為嚴重的損失，更可能擴大蔓延至鄰近地區。由於 大部分縣市近期内無法進行都市更新及整建舊市區，故對舊市區民眾避難安全實極為都 市防災重要之一項議題。
本研究將以新北市新莊區境内之舊市區為研究實證地區，並針對該地區目前現有已 設置之緊急避難據點進行研究，探討是否於災害發生時符合民眾之避難需求。本研究主 要是以應用Sinmlex電腦軟體為方法，模擬民眾以群體步行速度從居住處所經道路或避 難替代通路抵達避難據點之時間。研究結果將顯示新莊舊市區民眾因避難產生途徑及避 難場所功能不佳之處，期望對未來提出建議，改善或增設避難場所，以確保現行都市市 民之安全。

As the highly development in the city, it became a dense population gathering and economic prosperity area. In the cities, the old urban areas evacuation systems were insufficient in urban planning. High density of population, old buildings, narrow streets and lack temporary refuge areas in the area are the characters. If there is disaster occurred, these factors will cause tremendous damages and losses to the people and their properties. For the city government cannot proceed a renewal or rehabilitation in recent time, the people lived in old area still have to facing the potential danger of disasters. So, this is an important issue of urban disaster prevention for the concerning of the public safety.
This research took old urban area of the Xin-Zhuang district as experiment area to study the emergency evacuation system that included the evacuation routes and temporary refuge places. The research results could be reference for adjusting evacuation and adding evacuation refuges. The research used the computer software “Simulex” to simulate the people escaping from their living places to the refuge place in order to calculate the duration time of evacuation. The results reveal the shortage of temporary refuge places and inadequate of evacuation route systems. The research will offer the suggestions about the refuge places settlements and route system improvement that ensuring the security of people living in old urban area.
