The last numbers on development of the OSM coverage in Switzerland were from early 2012. Since then we have had on the one hand the licence change process with a small corresponding loss of data, and on the other hand quite a lot of interest in the project as a whole. So I beleive an update is in order. While I didn’t use quite the same methodology as the previous numbers presented in the wiki here, they seem close enough to be comparable.
The statistics show an increase of a total of at least 10’000 km from 142’000 km at the beginning of the year to 152’000 km now. This without taking a further 8’000 km of “service” roads in to account that were not listed separately in previous statistics. As would be expected the length of all roads with higher classification does not show much movement, a clear indication that the major road network is very complete.
The low number for the length of combined footway/cycleway would seem to indicate that we are mistagging the most frequent occurring type of cycleway.in Switzerland. What is further slightly surprising is that we have mapped a combined length of 1500 km of driveways and parking aisles, this would seem to be an awful lot compared to roughly 1300 km of cycleways.

I am traing to do the same for romania, to show how much kilometers are. Can you help me with a solution for this ?
The statistics are produced from an osm2pgsql database loaded with a Switzerland extract from GeoFabrik, this should be easiably doable in an Umbuntu VM for Romania. I do use a custom osm2pgsql style for the import, but that is about the only thing special. If you want the style file, plus the couple of SQL queries, send me a mail.
