unusual_trip_filter sets the trip_type for trips that have an unusual pattern for a route. The input GTFS must pass the feedvalidator without any warnings or errors.

Details

The pattern of a trip is the sequence of stops it visits. By default a trip is marked as unusual if its pattern is used by less than 10% of the trips of that route. See http://groups.google.com/group/gtfs-changes/browse_frm/thread/557dd991c453807a for more information about trip_type.
