A Modified Floor Field Model and Pareto Optimum of Pedestrian Evacuation Efficiency

الملخص EN

A modified floor field model is proposed to simulate the pedestrian evacuation behavior in a room with multiple exits.

The modification relies upon introduction of a so-called semidynamical floor field which additionally embodies two cognition coefficients related to exit width and pedestrian distribution around exits.

The energy consumption and time requirement of evacuees are numerically investigated and the Pareto optimum of evacuation efficiency is obtained by selecting the combinations of the two cognition coefficients.
