A pedestrian flow model at primary school gate after school

Based on the pedestrian flow patterns of primary students, this paper investigates the features of pedestrian flow under the rules of the certain scenario. During the primary students' evacuation process after school, various pedestrian behavior takes place, including pedestrian uneven distribution, pedestrian's input and output according to certain rules, paired phenomena and congestion phenomena. This paper uses the cellular automaton model and the static floor field to propose a pedestrian flow model and design an algorithm to calculate distance earnings of next move. This method is applied to simulate the evacuation behavior of pedestrians at the gate of Affiliated Primary School to Beihang University after school. The simulation results indicate that the input rate and the number of pedestrians at the initial stage have significant impacts on the evacuation efficiency and that there is a negative correlation between the average evacuation time and the initial number of pedestrians.
