Crowd Behaviour

Here's a simulation on how a crowd will probably react during an emergency, rushing towards an exit.

This reminds me of my secondary school. There's only one exit when the school bell goes off. And its 1 1/2 meters wide. I estimate about 600-700 students trying to cram through that gate within 10 minutes. The school principal had the second gate closed due to ' safety' concerns.

Go figure.
