Mr. Brendan Allen:

It was based on evidence. I do not remember if the AsIAm researcher Stuart Neilson's original qualification is as a mathematician or a statistician. He analysed movement throughout the campus and based on that he found that the majority, let us say 10,000 people moved this way, and alterations in signage, wayfinding and such things would enable someone with sensory needs not to be caught in the crowd of 10,000 people going one way. It is one study in one place at one time. Certainly, we could pick and choose many aspects of that according to the setting. DCU is a relatively modern university, with relatively modern layouts. It would not necessarily work for Trinity College Dublin which has cobblestones, older buildings and so on, but aspects of it could certainly be taken and applied to different settings.
