A Modified Floor Field Model Combined with Risk Field for Pedestrian Simulation

A Modified Floor Field Model Combined with Risk Field for Pedestrian Simulation

Microscopic evacuation models are of great value in both scientific research and practical applications. The floor field (FF) model is one of the most widely used models in previous research. However, the repulsion effect of hazard and the interaction between evacuees are not considered simultaneous...
