length of roads in an area

[Eric Lambert]

Hello,

I am wondering if there is any method to determine the length of a number of road
segments (total length) within a given area (vector length within raster area).

I can do a v.to.rast on the roads and run r.report, but this is not ideal.

Any ideas?

THanks.
