As Antarctica is international space,[1] I understand that, in
principle, the highway classification scheme of no particular country
applies there. For a while, I tried to come up with a balanced generic
scheme based on the regional importance of these roads,[2] which has
been questioned,[3] so I would like to hear opinions on the matter.

Should the classification of highways in Antarctica:

1. Follow country-specific conventions near stations? This can lead to
different classifications for long polar traverses maintained by
different countries and can create disconnected road networks (in
terms of classification) between nearby stations operated by different
countries.

2. Follow generic OSM definitions based on absolute population
thresholds of the places they connect? (10k+ people for town, 1k for
village, 100 for hamlet, etc.) This will assign very low road classes
across the continent.

3. Follow generic OSM definitions based on lower place population
thresholds that are more compatible with the reality of the continent,
based on regional importance? [4] The result may be perceived by some
as assigning higher than normal highway classes to the connections
between these small settlements.

Additionally, should the permanent population be considered (zero in
most cases, which is the case even for larger stations, further
lowering highway classification), or the average occupancy of the
stations?
