-
Check for mirror image if first and last sector + consecutive sector belong to same country region exception. If all cities belong to same region - consider it as Doubleback
If City level and Exception level fail, check for mirror image at country level.
If all cities belong to same country, consider it as doubleback (domestic)
02.Circuity
-

-
If at country level it is not a circuit, but at city/sector level it forms a circuit, still it should not be set as CIRCUITY
IF not a circuit at country level, but forms a circuit at Region/Country Exception with first and last sectors of the itineraries, then it is a CIRCUITY
03.Retraction
If NOT ALL points after the furthest point are within permissible range, then it is OpenJaw
If ALL points after the furthest point and the end point are within permissible range, then it is Retraction-OneWay
If there is a reduce in the GDC after the furthest point, then it is retraction
04.Normal
Itineraries which do not fall under Doubleback, Circuity or Retraction - they should be normal trips. The farthest point will be the last point in the itinerary
If an itinerary is not doubleback/circuity and GCD for any of the sectors is unavailable , then set it as OneWay-Normal
Trip Itinerary is to be used to derive the Journey Type and Trip OD
For inactive segments, the Journey Type will be null
