I’m currently working on a research prototype to try and figure out how to compare train, plane and car journey’s plus a combination of those where you calculate the time to the airport by car, time to the train station by car and include that in journey planning.
Can Graphhopper by used like this, if it can, can you give me some pointers as to how to do implement this using Graphhopper?
Note, that all use cases that require a timetable like flights or railway might only be correctly modelled via a time-dependent graph which we only support for our GTFS module at the moment.
