With the rapid development of society, the process of the Urbanization and continuousimprovement of people’s living standards, more and more the large sports are held, inrecent years our country has hosted the Beijing Olympic Games, the Asian Games andother major sports. However, with the number of the sports increased,some stadiumhappen the few activities stampede incident that in the reason of the people are not clearrealize on the pedestrian flow characteristics to import and export, transportation hub,underground passage, overpasses, which cause Adverse social impact. Therefore theresearch on large stadium or entertainment of pedestrian flow characteristics for designingthe stadium facilities reasonable, and there is a high theoretical value for the trafficorganization to provide guidance and support.Pedestrian flow is made with various features of the pedestrian system, in order toresearch and describe pedestrian flow, scholars have proposed various pedestrian flowsimulation model, which has the social force model, the lattice gas model and cellularautomata model, and in which, due to cellular automata using rules to describe the behaviorof the individual is pedestrian flow approach to the simulation and analysis of pedestrianflow and complex phenomenon, and which is easy for computer simulation and widelyapplied in the research of pedestrian flow.This paper start from the definition of cellular automaton, discussed the structure andcharacteristics of cellular automata, and based on which, describe the definition andcharacteristics of a one-dimensional cellular automaton, and analysis of the elementarycellular automata and Wolfram rule184. Then, the paper research on pedestrian trafficfrom three aspects of the visual and attention, psychological factors and behavior, and onthe basis of which the paper research the definition of queuing system and channel ofpedestrian flow parameters, and finally analyzed and studied the cohort of pedestrian flowand channel undertook thorough by the queuing theory and observational data in detail.At the same time, based on the queuing theory, the paper analyzes the characteristicsof arrival rate and serving-time, meanwhile, we divide queuing behaviors into a set of rules.Finally, the CA model of single-corridor with single service counter is built. Using Matlabsoftware we can see the flash of model. The simulating flash verifies how the serving-timeshould change in order to fit the requirement of queue length and offer a method tocalculate dispersing time in which the pedestrian was accumulated from unstable state.Compared with the reality, I found it conform with the real situation. So the model offersreference to the institute whether it necessary to add service counter or raise their servicerate. In the way of pedestrian flow in passageway simulated experiments, formulated thehigh expectations speed and low expectations do pedestrian speed simulation scheme,comparison and analysis on the fitting curve between the two basic parameters of therelationship between the flow data, and concludes that the high expectations of people donot easily transit from congestion state to the crowded conditions.
