I'm not clear if the routing is realtime or computed in advance, but
I'm not sure
more traffic information makes any difference whatsoever to the
"noise" suggestion.

I might be missing something, but assume that there are N drivers with
the same satnav system. Now, they get an update on traffic and are
diverted to an alternate route. Without some fudge/noise factor,
wouldn't you simply be moving the congestion to another route?
(Assuming that N is a significant number of drivers, and they are
fairly close together on the preliminary congested route).

Thanks,
Gerald.
