Unique GTFS Stop Sequence

To create NeTEx Route and JourneyPattern, Chouette Convert identifies each unique Stop sequence defined by GTFS Trip and their Stop Times.

For example, these GTFS Stop Times:

trip_id,stop_id,stop_sequence
STBA,STAGECOACH,1
STBA,BEATTY_AIRPORT,2
CITY1,STAGECOACH,1
CITY1,NANAA,2
CITY1,NADAV,3
CITY1,DADAN,4
CITY1,EMSI,5
CITY2,EMSI,1
CITY2,DADAN,2
CITY2,NADAV,3
CITY2,NANAA,4
CITY2,STAGECOACH,5
AB1,BEATTY_AIRPORT,1
AB1,BULLFROG,2
AB2,BULLFROG,1
AB2,BEATTY_AIRPORT,2
BFC1,BULLFROG,1
BFC1,FUR_CREEK_RES,2

BULLFROG,FUR_CREEK_RES
FUR_CREEK_RES,BULLFROG
BEATTY_AIRPORT,AMV
AMV,BEATTY_AIRPORT

The GTFS Stop sequence identifier is created from this list of GTFS Stop Identifiers.

For each GTFS Stop Sequence, Chouette Convert creates a NeTEx Route with the following information:

GTFS Stop Sequence	Details	NeTex ServiceJourney
GTFS Stop Sequence identifier		`id`
`route_id`		`LineRef`

<Route id="BEATTY_AIRPORT-AMV" version="any">
  <LineRef ref="AAMV"/>
</Route>

For each unique GTFS Stop Sequence, Chouette Convert creates a NeTEx ServiceJourneyPattern with the following information:

GTFS Stop Sequence	Details	NeTex ServiceJourney
GTFS Stop Sequence identifier		`id`
GTFS Stop Sequence identifier		`RouteRef`

<ServiceJourneyPattern id="BEATTY_AIRPORT-AMV" version="any">
  <RouteRef ref="BEATTY_AIRPORT-AMV"/>
  <pointsInSequence>
    <StopPointInJourneyPattern id="BEATTY_AIRPORT-AMV-1" version="any" order="1">
      <ScheduledStopPointRef ref="BEATTY_AIRPORT"/>
    </StopPointInJourneyPattern>
    <StopPointInJourneyPattern id="BEATTY_AIRPORT-AMV-2" version="any" order="2">
      <ScheduledStopPointRef ref="AMV"/>
    </StopPointInJourneyPattern>
  </pointsInSequence>
</ServiceJourneyPattern>

For each Stop in the Sequence, Chouette Convert creates a NeTEx StopPointInJourneyPattern with the following information:

GTFS Stop in Sequence	NeTex StopPointInJourneyPattern
GTFS Stop Sequence identifier + order	`id`
order in sequence	`order`
`stop_id`	`ScheduledStopPointRef`
