[OSM-talk-be] Fietsstraatzones in Leuven and a question about zones inside zones

[Tim Couwelier]

F4a should remain yes, despite both implying the same speed limit, UNLESS
the local gov removed the F4a signs due to the 'fietszone' completely
overlapping with the 'zone 30'.
Ideally, for the 'zone 30', differentiate between 'normal' with F4a only
and 'school- zone 30'  (F4a + A23)

If there's living streets within, I'd say the restrictions 'stack': no
overtaking, 20 km/h.
There may actually be a slight nuance here - generally in case of possible
contradiction, the rule applies 'traffic sign takes priority over traffic
rules'. The speed limits in both fietszone and living_street are traffic
rules, but this might leave a loophole where 'zone 30' as a sign takes
priority.

There used to be a loophole where a C43 70km/h would trump the 50km/h speed
limit in a built up area until the first intersection (extent of the
validity for the C43) but afaik that's been 'patched' in legislation now.
This might just be an unforeseen edge case opening another such loophole,
although I'm not 100% sure on this.


Sidenote: I think I agree with not making a seperate sign for this, but
just giving it a 'zonal' extent. If anything, F4a/b signs existing as such
is confusing. But then again, so were the original streetsigns as they were
semi-assumed to be zonal, but the law wasn't overly specific (and didn't
mention it being zonal). Readability, in database or map format, is far
better if you speak of 'zonal C43' and 'zonal F111' without having to know
another number for the same type of thing.
