Hi Jon!

If possible, please respond to previous messages to keep them nicely

Usually, it is the other way round: JOSM supports those features and 
mapping techniques that are commonly used by the mappers.

In my impression, north/south/… is quite different from 
forward/backward. Most of JOSM's handling of the roles forward/backward 
related to determining in which way those ways are traversed by the 
specific bus/train/* routes, and sorting the relation members 
accordingly. These aspects seem trivial to me for north/south/… since 
all relation members are oneways and only traversed in that direction.

Btw: the newer public transport scheme basically deprecated 
forward/backward in favour of separate relations per direction. How does 
the US highway mapping relate to this scheme?

Cheers,
Simon
