A library of GTFS Realtime translators (for transit data)

In plain words

A library of GTFS Realtime translators converts transit data from various formats into the GTFS Realtime standard. It is designed for developers and transit agencies working with public transportation information systems. The library enables interoperability between different transit data sources by providing translation tools, making it easier to integrate diverse data feeds into unified real-time transit applications.

The source code is here if you are interested:…
