That's actually pretty much common knowledge with experts studying people flows and emergency evacuations.

If you're interested in the subject The New Yorker has a fascinating read on the subject (CRUSH POINT - When large crowds assemble, is there a way to keep them safe? [2011]) which makes this argument. (Warning! It's long)

Thanks.

Hanging my head in shame for the omitted link.

Sorry for the oversight, since it's a really interesting read.
