Dla mnie transport to transportation, ale juz wiem dlaczego :)
Where Americans use transportation, Britons generally prefer transport. In American English, transport is only a verb (with rare exceptions). So where Americans say public transportation, transportation commissioner, and air transportation, Britons say public transport, transport commissioner, and air transport. Neither transport nor transportation is right or wrong; they’re just different ways of saying the same thing.
Canadians use both transport and transportation, though the latter has the edge. Australians favor transport.
