Live Traffic Data

Hello everyone !

My project is to develop a web application based on a map and a navigation system.
I would like to know if there was a tool to display traffic on OSM? Preferably a solution that we could host on our own servers to avoid dependency and all problems (eg OpenTraffic which has been abandoned)

Thank you in advance for your answers to all!
