[pgrouting-users] very hight costs

[Pedro Costa]

Hello,


I'm working with pgrouting and costs. When i want that one road can not 
be used i give it a very high cost. But my question is, there is a value 
that makes the pgrouting not consider this alternative? Like '-1'?
Because if this option is the only, does not mattercost, that this road 
will be selected.

Anyone knows more examples about costs with pgrouting?

Thanks
