Analysis of Impact of Guiding Signs on Evacuation Decision-Making Process

Abstract

The efficiency of emergency evacuation signs is influenced by its visibility catchment area (VCA) and pedestrian behavior and route selection in the evacuation. In order to describe the pedestrian route selection process in evacuation in specific subway station signs’ VCA, we identify the signs’ properties which influence the efficiency of emergency evacuation signs and check the parameters of facility layout structure which affects VCA through investigation and analysis of test results, then constructing decision-making behavior model of pedestrian evacuation route selection base on the analysis of different route selection behavior during evacuation. This paper simulates the process of route selection in evacuation through AnyLogic and then analyzes the influence of the emergency signs’ location, the initial evacuation volume and the success rate of pedestrian interaction on the evacuation time by simulating the process of route selection in evacuation.
