I aim to "translate" GTFS files (non realtime) into directed graphs. Is there any API / tool that can do that easily ? I would like to create a graph per route in my GTFS, and then store it into a file.
So far I made a few tests using Python and pygtfs, or R and gtfsr, but none seems to be able to make that conversion.
You can try peartree. Their websites says: "peartree is a library for converting GTFS feed schedules into a representative directed network graph."
