The word 交通 is a compound word. It is formed from two kanji: ⚫︎ 交 (kou) - which means "to cross," "to intersect," "to come and go," or "to exchange". ⚫︎ 通 (tsuu) - which means "to pass," "to go through," or "to communicate". Therefore, 交通 literally means "to cross and pass," or, more broadly, to facilitate the movement or exchange between two points or entities.
