The key =* is used in public transportation tagging to add the trip_id from the GTFS trips.txt file to a PTv2 type=route relation.
Please, use gtfs:shape_id=* if present in trips.txt or shapes.txt as it better fits.
=* should only be used if the route variant represents only one single trip with only one service_id. Otherwise, please, use gtfs:shape_id=* or gtfs:trip_id:sample=*.
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
Example
Look at the route Bus 10: Ringlijn Nijmegen Centraal Station => Universiteit HAN. It is a route so we can find the corresponding trips 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 =177374763.
But in this case gtfs:trip_id:sample:NL-OVApi=177374763 is preferred because the route has multiple trips.
Even better would be using gtfs:shape_id:NL-OVApi=1127909 since this particular feed has different trip id's between feed versions.

PTNA
PTNA represents =* on its pages about GTFS trips and in the network analysis (overview) under the tags summary.
=* is evaluated by PTNA to link from the analysis to the GTFS data if additionally network:guid=*, operator:guid=* or gtfs:feed=* is present (example).
Adding the gtfs:route_id=* does not harm but is not needed as it is derivable from gtfs:trip_id:sample=*
