[GRASS-user] Highway alignment

[H.S.Rai]

Is it possible to find optimum alignment for highway. For given DTM,
to find alignment between two points A and B, which satisfy a number
of requirement (like gradient/slope, passes through villages having
hospital and through maximum number of other villages (minimum 2
villages) within given area, and having minimum cost). As I could not
find any such information in documentation available on Internet, any
pointer, suggestion or reference to person who has done such project
would be appreciated.
