We are thrilled to announce that the OpenStreetMap Foundation has been selected by the Sovereign Tech Agency for a service agreement in the amount of 384,000 EUR over two years to ensure the stability, growth and modernization of OpenStreetMap’s core software.
Their live traffic data’s comes not from OSM. It is not publicly known what their source is for this data.
They say they use crowdsourced data, presumably from users, then “send it to a provider” to combine with other data. Not ideal, but (hopefully) not Google. LOL
I don’t think you can have in-house live traffic data without having many million active users. But it would be nice!
