地道的说法是 congestion 交通堵塞，或 congested.E.g., You should have seen how congested the highway was this morning.There is so much congestion during the morning hours, so I quit driving.答完了才意识到答非所问，不好意思。交通不便。 国外的交通不便主要是指缺少公共交通设施， lack of public transportation; 或堵塞。 你说的交通不便可能是有其他原因，不如你说 traveling inconveniences caused by lack of public transportation/ lack of city infrastructure [on roadways].
