These signs and the typeface are my gold standard. I've traveled to dozens of countries, and I still think the British signage is the cleanest and clearest in the world.
James May did a car "review" with Margaret Calvert years back in an episode of Top Gear. Was a bit of a departure from regular Top Gear but certainly interesting https://www.youtube.com/watch?v=wTDB3dpe3eg
I love Transport and it absolutely evokes Britishness for me whenever I see it. The "Highway Gothic" [1] font used on US Interstate highways (and apparently also in Australia and Canada) is also pretty good I think and similarly evokes the open road in my mind.
