One of the interesting things about the facts in this thread is the behaviours of humans. The same behaviour I have referred to numerous times now with regards to a crossing at the rear of the station.

Those who cross roads properly make a habit of it, and will use a crossing if available. Those who are too important or impatient will simply take any risk necessary to get across the road as quickly as possible.

Waiting 60 seconds for a crossing to make it safer to do so clearly doesn't compute for some.

There is always room for improvement in road safety, from every angle. The question is, does the purse allow for it? And at what point do you throw every penny you have at something, in order to eliminate the humans responsibility in the matter?
