you might want to checkout

https://github.com/linkedconnections/gtfs2lc

and

https://github.com/OpenTransport/gtfs-csv2rdf

And linkedconnections in general. Pieter does great work with this data.

In case you still want to do it on your own for whatever reason I would
recommend our CSV on the Web based parser, which is streaming-capable.
GTFS generates a *lot* of data so streaming is a must.

https://github.com/rdf-ext/rdf-parser-csvw

This is for example used here: https://github.com/zazuko/blv-tierseuchen-ld

Node.js based, not JVM.
