Unable to answer "What is the speed limit sign for this street?" for osm.org/way/31009030 via StreetComplete 2.0:

no speed sign, but instead, one way, from Hidegkuti tó Galóca

It is possible to walk down the Zsibói utca, then there is a lepcső down to the fogaskerekű and you can even cross, as on the other site at the rőzse utca/kőz there is a lepcső again

How do I restrict access to only part of the Tamasi Aron utca? In between Fodor utca and Martonhegi ut, the street is closed but for destination traffic (celforgalom).

Kisdoboz koz renamed to: Tersánszky Józsi Jenô köz
