[Open-transport] Stream of stoptimes to GTFS

Fri Dec 19 12:06:43 UTC 2014

Hi Thomas,

No, I'm trying to first get a stream of "stoptimes" [1], which can 
indeed also be scraped through what you've referenced (implementation 
detail I would say). This stream of stoptimes is fairly easy to get, for 
any operator, for any mode. If we can now write code to convert streams 
of stoptimes to GTFS, we have introduced an intermediate step where a 
lot of other projects can start.

Kind regards,

Pieter
