The following "channels" are available to ask questions: http://pgrouting.org/support.html
The Gitter channel is in general a good place: https://gitter.im/pgRouting/pgrouting

from osm2pgrouting.

I agree that a bit more documentation might be good to have.
However, the formula is available in this SQL:

Maybe it would be better to leave the cost computation to the user, as also discussed recently here: #275 (comment)

Dear dkastl

what the meaning og (maxspeed_backward::float * 5.0 / 18.0)? can I modify it as neede in osm2pgrouting?

bawidyantoro, it's just sql-code. You can execute it later in your database. But you have to modify the WHERE part, cause it only updates the fields that contains NULL.

In your case, I would take a look to the file that Daniel pointed to: osm2pgrouting/src/database/Export2DB.cpp
