One possible option (although admittedly somewhat brute force) is to use 
v.to.points, playing with the dmax parameter in v.to.point or with the 
symbol size to differentiate.

You can only use symbols that are the same in all directions (e.g. 
circles) since the orientation of the symbol will not follow the 
orientation of the line.

See attached screenshots based on the North Carolina demo data 
roadsmajor map.
