Even one way roads can have multiple lanes. Like dual carriage ways :)

I feel you could get road widths accurately enough based simply on the number
of lanes and the type of highway.
For example, a residential road with 2 lanes, one in each direction is usually
about 6-7m wide.
Motorways are usually the numbers of lanes times 3m + 3m each side of the road
way to allow for break downs, or maybe you could even have lanes=*
breakdown_lanes=* to make this more accurate, but in any case a 3 lane motorway
will be about 15m wide (3 * 3 + 3 + 3).
