The
system is in
devel status now. The secondary routes are being drafted based on the
route log from 2022-04-01. OSM indicates the Z routes quite well while GM does not indicate them at all. The routes were not signed in the past but first signs appeared a few years now (5 years?). They are well signed now, as we can see on recent GSV, e.g.
Z2023.
There should be 1,070 Z routes for 9,359km (5,815mi) according to the 2022 route log.
The route log only indicates routes outside of (larger) towns albeit OSM often (but not always) extends them inbound. The route log indicates them starting at e.g. "A. G. Grada Zagreba" i.e. Zagreb boundary. That means, they don't extent beyond municipality boundaries. Thus, a lot of routes - especially in Zagreb area - won't make it into the HB.
