Abstract
By considering previous empirical studies in group dynamics, modelling designs for pedestrian simulators and psychological and sociological theories of crowd behaviour, we briefly present a hierarchical, identity-based approach to simulating pedestrian social groups.
Highlights
Social and emergent group behaviour in crowds has garnered enough attention that [1] present a review of research
Environmental stimuli cause implicit changes in agent behaviour as a direct result of ‘cognitive’ functions. This approach lends itself to tackling emergent lane formation (e.g. [10]) and other phenomena where environmental conditions alter behavioural motives
We propose that it is Social Identity Model of Deindividuation Effects (SIDE)’s emphasis on the salience of social and personal identities, and the resultant partialdeindividuation that should be utilized in social group models
Summary
Social and emergent group behaviour in crowds has garnered enough attention that [1] present a review of research. SIDE presents an agent with one or more social identities and a personal identity, each of which influences to a greater or lesser extent the behaviour of the agent [13]. [16] already consider such identities to model helping behaviour amongst strangers during emergencies. We propose that it is SIDE’s emphasis on the salience of social and personal identities, and the resultant partialdeindividuation (employed here as shared behavioural approaches) that should be utilized in social group models.
