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:

Chouette Concert will identify the following Stop sequences:

STAGECOACH,BEATTY_AIRPORT
STAGECOACH,NANAA,NADAV,DADAN,EMSI
EMSI,DADAN,NADAV,NANAA,STAGECOACH
BEATTY_AIRPORT,BULLFROG
BULLFROG,BEATTY_AIRPORT
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	NeTex ServiceJourney

GTFS Stop Sequence	NeTex ServiceJourney
GTFS Stop Sequence identifier prefixed with `Route:`	`id`
