交通堵塞(关键词：Tokyo, narrow lanes, radiating highways, overcrowded, parking, blaring vehicles.)

Much of the street pattern of Tokyo dates to historic times and is made of narrow, crooked lanes that are unsuitable for heavy use by automobiles. The radiating highways and expressways that were put in to modernize the road network are usually badly overcrowded, and traffic moves at a slow pace. Parking is a major problem. A person must provide proof of an off-street, overnight parking space to own a car in Tokyo.
