How to customize route proposal by trace database

Hello everybody,

I start use open source routing engine in my own server for a personal project.

My question is : its possible if i’ve a database of trace (like gpx) to customize routing? If people use a route, I would like the engine to take it into the proposal route.

I hope my question is clear, i search in the forum, but don’t find anything… or didn’t make a good search… :grinning:
