Unable to answer "Does this road have lane markings?" – Tábor utca (Residential Road) – https://osm.org/way/315045848 via StreetComplete 63.0:

This is a junction, and it does not make sense to set the number of lanes in such a junction IMO. But every road coming to it has a single lane in each direction. The photo is facing northward.
