Thanks for replying and link (info we cant legally use in OSM) and routers don't care about abiding or not. The pedestrian zone combod with no stopping sign and vehicles is telling. OSM has no solution for ZTL tagging meaning periodic closure but for foot (and bike here in IT at 'veloce moderato'). We call it ATL here but it's exactly the same, it's split in 5 zones for which residents have a zone N permit. Anyway, the square being a parking lot is the escape clause, it has a painted way to get to Spedalieri If it can be made out in the recent OSM aerials or you confirm to have now 'local knowledge' post 'survey', the way can be mapped without OSM rule infraction. motor_vehicle:conditional=yes @ destination may be called for on the ZTL streets.. The digi displays here at zone entrance points with ATL active of not-active' is how outsiders learn when not to drive in. The pedestiran sign effectively telling 5 kmh maxspeed. Many cycle ways here have 10kmh sign when shared with foot or a 'velocità moderata' sub-sign

thanks again.
