An extended floor field model based on regular hexagonal cells for pedestrian simulation

Recently the floor field (FF) model has been widely used to simulate pedestrian dynamics. This paper presents an extended FF model based on regular hexagonal cells to simulate pedestrian dynamics in a corridor scenario. In this model, the elements in FF model are redefined. Scenarios are discretized into regular hexagonal cells rather than squared ones. Pedestrian repulsion is adopted instead of dynamic floor field. Velocity level is proposed to describe pedestrian movements. Simulations in a corridor scenario are conducted, and the basic property of the new model is discussed deeply, including the parametric effects on flow and wait distribution of pedestrian. The fundamental diagrams of pedestrian dynamics are used to verify the model. (C) 2014 Elsevier B.V. All rights reserved.
