The key gtfs:trip_id:sample=* is used in public transportation tagging to add one trip_id from the GTFS trips.txt file as example to a PTv2 type=route relation.

Please, use gtfs:shape_id=* if present in trips.txt or shapes.txt as it better fits.

If the route variant represents only one trip with a single service_id gtfs:trip_id=* is an alternative key to use.

The key is used to find the corresponding trip in a GTFS feed. For this the feed needs to be specified using a feed code suffix (see List of GTFS feeds). For a longer explanation on how to reference a GTFS feed, look at GTFS.


Look at the route Bus 10: Ringlijn Nijmegen Centraal Station => Universiteit HAN. It is a relation route so we can find the corresponding trps in trips.txt

Below is an excerpt of that table.

route_id service_id trip_id trip_headsign trip_short_name trip_long_name direction_id shape_id ...
87987 457 177374763 Heyendaal 79 0 1127909
87987 457 177374758 Heyendaal 69 0 1127909
87987 457 177374753 Heyendaal 59 0 1127909

We can refer to one of these using gtfs:trip_id:sample:NL-OVApi=177374763.

Using gtfs:shape_id:NL-OVApi=1127909 is preferred since this particular feed has different trip id's between feed versions.


PTNA represents gtfs:trip_id:sample=* on its pages about GTFS trips and in the network network analysis (overview) under the tags summary.

gtfs:trip_id:sample=* is evaluated by PTNA to link from the analysis to the GTFS data if additionally gtfs:feed=*, operator:guid=* or network:guid=* (in this order) is present (example).
Adding the gtfs:route_id=* does not harm but is not needed as it is derivable from gtfs:trip_id:sample=*
