  The influence of agents heterogeneity on the microscopic characteristics of
pedestrian flow is studied via an evacuation simulation tool based on the
Floor-Field model. The heterogeneity is introduced in agents velocity,
aggressiveness, and sensitivity to occupation. The simulation results are
compared to data gathered during an original experiment. The comparison shows
that the heterogeneity in aggressiveness and sensitivity occupation enables to
reproduce some microscopic aspects. The heterogeneity in velocity seems to be
redundant.
