Tom,
I was thinking along different lines ... in terms of evacuation, the
emergency service is greatly helped by knowing:
- how many evacuees they're dealing with and who these are; and
- how many received the message.
In this way, the fire authorities can know several things:
- Did everybody get the evac message?
- How many people will be heading along which evacuation routes?
- Are we risking a dangerous concentration of evacuees in a particular
area? (For example, we can send 100 people to the sports field, but not
3000).
Cheers,
RC
