Where can I get data to display traffic on the osm map?

Question

JavaScript

There is a map on the front, a leaflet and an osm substrate are used. It is possible to edit geo data on the map, vector layers are in PostgreSQL. The task is to display traffic jams on the map, I want to know where you can get data from (tiles, geometry), are you interested in both paid and free options?

Answer 1

There is practically no complete open data on traffic jams on the territory of Russia. Commercial suppliers have them - for example, Yandex. https://tech.yandex.ru/maps/jsbox/2.1/traffic_cont...
However, Yandex prohibits the use of its data outside of its maps API, which means that you cannot use it in a leaflet.
