Simulation of Groups within Crowds using Social Forces (English)
Abstract [sv]

Simuleringar av folkmassor är användbara i ett flertal industrier som i underhållning, robotik samt evakueringsplanering. Social force modellen (SFM) använder en mikroskopiskt förhållningssätt och kan simulera interaktioner mellan enkilda agenter, modellen saknar dock gruppbeteenden vilket är en viktig aspekt i de flesta industrier. Denna studie bygger vidare på att inkludera gruppbeteende i SFM genom att introducera ytterligare en gruppbaserad kraft som skapar samhörighet hos grupper. För att uppnå realism föreslås ytterligare vikter för att minska de stora förändringarna i agenternas orientation. Vi jämför olika simuleringar av rumsevakuering samt ansträngda samspel mellan grupperna med empirisk data och diskuterar modellens användningsområden. Resultatet indikerar att modellen är tillräcklig för evakueringsplanering samt realtidssimulering för folkmassor med låg densitet.

Abstract [en]

Crowd simulations are useful in a variety of fields including entertainment, robotics and evacuation planning. The social force model (SFM) uses a microscopic approach and simulates interactions between single agents, it does however lack group behaviours which is an important aspect in the majority of the fields of application. This study further develops and extends SFM to include group behaviour by introducing a new group related attraction force that adds cohesiveness within groups. To achieve realism, additional weights are proposed to reduce big orientation changes by agents. We compare different simulations of room evacuation and forced interactions to empirical data and discuss the usability of the model. The results indicate that the model is sufficient for evacuation planning and real time simulations for low density crowds.
