Introduction of frictional and turning function for pedestrian outflow with an obstacle

摘要: In this paper, two important factors which affect the pedestrian outflow at a bottleneck significantly are studied in detail to analyze effect of an obstacle setup front exit. One is conflict exit when pedestrians evacuate from room. We use floor field model for simulating such behavior, well-studied using cellular automata. The conflicts have been taken into account by friction parameter. However, parameter so far constant and does not depend on number conflicting same time. Thus, we improved frictional function, function involved conflict. Second, presented cost turning Since inertia, their walking speeds decrease they turn decreases. validity extended model, includes supported comparison mean-field theory real experiments. observed that flow increases put our analytical results clearly explains mechanism obstacle, i.e., blocks moving decreases average also found works more effectively shift it center since go through with less turning.
