  Clogging raises as the principal phenomenon during many evacuation processes
of pedestrians in a panic situation. As people push to escape from danger,
compression forces may increase to harming levels. Many individuals might fall
down, while others will try to dodge the fallen people, or, simply pass through
them. We studied the dynamics of the crowd for these situations, in the context
of the "social force model". We modeled the unconscious (fallen) pedestrians as
inanimate bodies that can be dodged (or not) by the surrounding individuals. We
found that new morphological structures appear along the evacuating crowd.
Under specific conditions, these structures may enhance the evacuation
performance. The pedestrian's willings for either dodging or passing through
the unconscious individuals play a relevant role in the overall evacuation
performance.
