引发交通社会问题的典型案例1 New York 20世纪40代|纽约第一次世界大战结束后,美国的经济开始蓬勃发展。为加快追赶老工业强国的步伐,汽车制造成为美国支柱产业。1929年,美国汽车产业的产值已占到全国工业产值的8%左右,汽车产量达到2,650万辆,占全世界总产量的六分之五。1919年~1929年,美国小汽车保有量由677.1万辆增至2,312.1万辆。以纽约为代表的美国东海岸城市由于经济发达,人口众多,城市化水平高,率先经历了交通拥堵。1900年~1929年,纽约人口由343万增至700万。小汽车由1,396辆增至25万。到1940年中心城区的交通拥堵达到令人难以容忍的程度,城市居民因为居住环境的恶化开始迁往郊区居住。到1940年之后,纽约市区人口几乎停止增长。
Typical Cases of Social Problems in Transportation 1 New York 40th Generation in the 20th Century | New York After the end of World War I, the U.S. economy started to flourish. To speed up the pace of chasing the old industrial powerhouse, automobile manufacturing has become a pillar industry in the United States. In 1929, the output value of the U.S. auto industry accounted for about 8% of the country’s industrial output value and the automobile output reached 26.5 million vehicles, accounting for six-fifths of the world’s total output. From 1919 to 1929, the number of American cars increased from 6,771,000 to 23,121,000. The cities on the east coast of the United States, represented by New York City, took the lead in experiencing traffic congestion due to its developed economy, large population and high level of urbanization. From 1900 to 1929, the population of New York increased from 3.4 million to 7 million. The number of cars has increased from 1,396 to 250,000. By 1940, traffic congestion in the downtown area reached an unacceptable level, and urban residents began to move to the suburbs for living because of the deteriorating living conditions. By 1940, New York City’s population had almost stopped growing.
