What good management looks like
Modelled flows, staggered entries, clear egress, signage in the eye-line, lighting steering movement, staff visible at decision points. The crowd never notices you working.
When control kicks in
Density spike, blocked egress, medical emergency in the middle of a crowd. Response is triangulated — control room coordinates, on-ground teams execute.
The failure mode you must avoid
Aggressive control when management failed. Physical intervention against a dense moving crowd escalates risk; opening pressure release and slowing entry does the opposite.
