Preprocess GTFS issue or Problematic gtfs data?

[ALEXBARTZOKAS]

Hi! I use the BetterBusBuffers tool and ArcGIS v.10.3 to analyze the Norwegian GTFS dataset (here). However, from the first steps and when I pre-process GTFS, I deal with several errors, such as invalid arrival_times, etc. Any ideas on how I can resolve these issues? Does the Interpolate blank stop times tool clean this kind of invalid arrival time?

Interpolate Blank Stop Times will only clean up blank values for the arrival_time column.  If you have invalid values like this one, you need to either manually fix the value with a good one, or delete the value so it is blank and then run Interpolate Blank Stop Times.
