Keep the project universal, not dependent on a particular navigation app

I came here via an Osmand ticket (osmandapp/OsmAnd#6878 (comment)), whereas the README mentions Organic Maps.

I would suggest keeping the traffic backend universal so it can work with any navigation app (of all FOSS navigation apps I know, Navit is currently the only one with support for traffic (based on TraFF, which was designed to be app-agnostic); Osmand and Organic Maps would need to have traffic support added). Being able to be used by as many apps as possible would enhance the user base of such a service – more people might be interested in contributing code and ideas, and once we start crowdsourcing traffic data, we’ll have a bigger user base, which in turn means better coverage, better accuracy and more up-to-date information.

#4 has some points on how to encode locations in a universal way that works with any reasonably up-to-date map. The TraFF specification at https://gitlab.com/traffxml/traff also has a scheme to encode event information (predefined event codes for what has happened, speed restrictions, delays etc.).
