[pgrouting-users] Driving Distance calculation documentation questions

[Anton Patrushev]

Hi Steve,

I think it is a bug, there shouldn't be 0 in cost column.
And no, you can't just sum all costs. What you can assume that the
final cost has the value you requested as a distance. At least not
bigger.
I really have no time right now to fix this problem, but I suspect it
shouldn't be difficult to find that place where final cost is
assigned.

Cheers,
Anton.
