Allow building of TransportNetwork without OSM network (GTFS only) #157

Open landonreed opened 8 years ago

landonreed commented 8 years ago

Allow building of TransportNetwork without OSM network (GTFS only) so that networks can be built quickly with GTFS feeds alone and allow comparison between feed versions without OSM data behaving as an interfering variable.

@mattwigway or @abyrd, what is the level of effort on this? My guess is that this could make the use of r5 in datatools a little more feasible for (very rough) isochrone generation.

I don't think this should be very hard. We need to make a transport network builder that only builds a transit layer, and then you would call the existing FastRaptorWorker access times derived from straight line distance. They would return travel times to all stops, you'd then just need stop to point distance tables derived from straight line distance so that the propagater would work.
