Collective Dynamics of Bidirectional Pedestrian Flows Considering Code Scanning Behavior

Based on the social force model, this paper simulates the code-scanning behavior of bidirectional pedestrian flows in the corridor. Different collective states of the pedestrians were found. The motion efficiency graph and the spatial state diagram to show the transition effect, When scanning time, number of codes, corridor width and other factors change, the collective mode of pedestrians in the corridor will present three states: free state, coexistence state and frozen state, and the transition will occur with the change of influencing factors. Long code-scanning time, few pedestrians, and narrow corridors will all lead to a higher probability of freezing state. This study shows that the interaction between pedestrians and QR codes can be adjusted to effectively avoid pedestrian blockage in the corridor, so as to realize efficient utilization of limited resources.
