At tourist attractions with large crowds, we have to consider evacuating large Numbers of pedestrians due to an emergency. This paper discusses the evacuation of tourists in emergency, analyzes the possible bottlenecks, and establishes a relatively complete evacuation plan. We considered that although the place is a three-dimensional model, in a certain stage of the evacuation process, each floor is independent of each other, and individuals on different floors do not influence each other. Therefore, according to the fuzzy cellular automata (FCA) model, we adopted the modular processing method to establish the two-dimensional evacuation model initially. First, we established the movement speed and time model of tourists, then introduced obstacle reference factor, direction reference factor and control factor to modify the direction selection of tourists, so as to carry out orderly evacuation.
