If you really are looking for some high tech info and want to impress. There is a computer model called exodus which is a evacuation simulation and pedestrian dynamics/circulation analysis.
If you have a look at the fire safety engineering group website, there is plenty to look round, as they have done extensive research on human behaviour in fire situations, using real fire scenarios etc. You can also view free clips of how exodus works and how human behaviour effects evacuations.

, but I found it fascinating.
Plus having some of those clips will do wonders for your presentation mate

The song goes...{I'm gonna walk down to electric avenue and I'm gonna say ' have you got PAT testing records for all that mate'}
