摘要

生活上常會有突如其來災難發生，當災難發生時人的心理會產生恐慌，因此在行為上往往會驚慌失措，因此需有緊急避難導引系統，一般避難導引設計上的考慮，主要以能避開災難地點，導引最短的逃生路徑，然而人群跟著逃生系統的導引，反而是造成人群擁擠傷亡情形的主要原因。
因此本研究利用影像前景偵測的方法，來評估逃生路徑人群擁擠度程度，擬訂一套逃生路徑人群動態導引系統，設計上依照危險的層級以避開災難區域為先，其次為人群擁擠區域，有效導引最簡易的逃生路徑，並且設計出一套完善的分散式避難導引演算法，以能分散人群的安全疏散路徑避免擁擠問題。

In cases of disasters, emergency evacuation guidance system is needed. The design of most emergency evacuation guidance systems concerns the avoidance of the disastrous area, and the shortest escaping path; however, such design may lead to overcrowding in some areas.
This study assesses the density of crowds on evacuation routes, and developed a dynamic guidance system, which sets the priority in the following order: avoid disaster area, crowd, effectively guide most easy path. It can provide proper evacuation guidance to avoid overcrowding.
