Think about it:
1) use tags on nodes to describe an area
2) use an area to describe an area

Generally speaking, I predict 2) will be easier.

Erm no. You need to know along which direction the width is measured.
You could *assume* that this is in the direction that bisects the
angle between the previous and following nodes, but 1) this is an
approximation and 2) this doesn't work if the node is connected to
more than 2 other nodes. Thus... nodes are hardly the "perfect point"
to indicate width.
