Hi. I don't know what ionic is. In OSM the speed limit is stored in the maxspeed
tag. A word of warning: Data in OSM is patchy, and only ~7% of highway
s in OSM have a maxspeed
tag. But many (all?) countries have default speed limits based on the road classification, and you can deduce this from the highway
tag value (or the ref
), so just because the maxspeed tag is missing doesn't mean that you cannot deduce the speed limit. However this requires you to know the speed limits (or road classifications) for the country/ies you're interested in.
