[pgrouting-users] very hight costs

[Stephen Woodbridge]

Yes, eliminating the segments with a where clause will work best because 
it reduces the number of segments and means that you can never travel on 
that edge because it is not there.

I believe the usage of -1 for a cost is algorithm specific and I don't 
know which ones accept this and eliminate the edges internally. I'm 
pretty sure TRSP allows -1 for a cost and drops that edge internally.
