Research on people search of metro station in the condition of low visibility after disasters
In recent years,public safety issues have received increasing attention from people.And the safety of subway station operations is one of the problem which lots of experts are concerning.At present,the emergency treatment research on the sudden situation of subway stations is mainly focused on emergency evacuation and emergency management.It rarely involves the post-disaster rescue field,but rescue is also an important process.This paper first analyzes the more commonly used directed search methods in the case of post-disaster low visibility.Next,it analyzes the search speed and effective search depth of firefighters in different search posture through directed search experiments.Then,it proposes an algorithm of time-balanced based on directed search in areal division and developes the simulation environment through C#.Last,it validates the method through a subway station platform in Beijing.The results show that the method can effectively divide the search area and the overall search efficiency is good.
