地道的说法是congestion交通堵塞，或congested.E.g.,Youshouldhaveseenhowcongestedthehighwaywasthismorning.Thereissomuchcongestionduringthemorninghours,soIquitdriving.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，lackofpublictransportation;或堵塞。你说的交通不便可能是有其他原因，不如你说travelinginconveniencescausedbylackofpublictransportation/lackofcityinfrastructure[onroadways].
