SOCIAL INTERACTION IN PEDESTRIAN EVACUATION: A CELLULAR DISCRETE EVENT SIMULATION APPROACH

摘要

This paper presents a cellular simulation model for pedestrian emergency evacuation, which takes into account social factors such as individual vision, environmental familiarity, communication and conduction, and velocity adjustment. Variables are introduced to describe the relationship between the evacuees and their environment, as well as the interaction with each other. RESTful CD++ has been used as a middle-ware to run simulations remotely. The results obtained confirm the role of social interactions in emergency evacuation. This work, on the one hand, shows the advantages and advancement of model-driven theory and DEVS formalism to address social science issues; on the other hand, it helps to better integrate evacuation planning and public safety management in the design of urban architectures.
