koutsuu
The word "koutsuu" covers a broader range of meanings than the English word "traffic." While it refers to the flow of vehicles on a road, it also encompasses the entire system of transportation (infrastructure, means of travel) and, in a more formal or historical sense, the social or diplomatic exchange between regions or nations.
In daily conversation, it is frequently used to describe the ease of accessing a location. The phrase "koutsuu no ben" (convenience of transportation) is a standard way to say a place is easy to get to via public transit.
When referring to "traffic jams," "koutsuu juutai" is the precise term. When discussing "transportation systems," "koutsuu kikan" or "koutsuu mou" are used. Be careful not to confuse it with "kouryuu" (cultural/social exchange), although "koutsuu" can mean exchange in a physical or historical context of traveling between places.
