I've read the wikipage on maxspeed tagging, but I have the following
questions:
- How does one tag the end of a zone, I cannot find the number of that sign
? Start zone should be tagged with BE:F4a
Zone traffic signs don't have numbers (with the exception of a zone 30 which
has a specific sign number). You could invent something like zone(C43[50]) for
a zone 50.
- How do you tag different speeds for 'cars' and e.g. +5t ?
Doesn't really have an agreed way of tagging. I made an effort solving this by
making http://mijndev.openstreetmap.nl/~eimai/verkeersborden/ (not finished,
don't look at the highway tags; use Firefox, maybe Chrome works as well).
Click the signs and the tags appear.
In this case it would be something like
maxspeed = 70
maxspeed[weight>5] = 50
It's sufficient that everyone understands it, the exact syntax doesn't matter
too much for now, since there are no programs able to read it anyway for now.

- In case I create individual nodes for the the traffic sign (as requested
on the wiki page), how do I indicate the direction for which the sign is
meant ?
This is an unsolved question... Some may use directions like N/E/S/W for
north/east/south/west. But then you also need to be able to attach the node to
the proper way (bridges and dual carriageways make this a difficult problem).
I would rather use the left / right suffixes in stead of directions, as
they define the position always clear
(eventually forward / backward, but it seems somewhat deprecated)
