Hi Gerd,
I have assumed, that option --check-roundabout gets a new algorithm, the
one that you have described. I would prefer that use of "dol/dor"
counting was controlled by user and option --check-roundabouts looks
prefect for this purpose.
I think that flags in IMG should be consistent, the one you have
mentioned in NOD and a flag in TRE. So any decision about
drive-on-left/right should be taken once and should force setting of
both flags.
My idea is that user can select following processing:
- Automatic detection of left/right by using --check-roundabout with
options --drive-on-left/right as a fallback.
- Forced setting with option --drive-on-left/right alone.
- Default setting when no options are used. Defaults could be taken from
LocatorConfig.xml or simply set as drive-on-right (hope this is more
common).
This description also defines priority of processing, with "dol/dor"
counting as a first choice, but only if user set explicit option.

Andrzej
