Just as the structure of American cities is different from that of European cities depending on their vintage, we can expect the 21st century Asian city to also exhibit different characteristics. The older European or Asian city is typically more densely populated and less spread out than the American cities, reflecting in particular the different degrees of motorization that existed at their inception.
American cities are much more dependent on privately owned motorized transportation than cities in the older continents. Even as early as the early 1970s, nearly 80 per cent of US urban commuters traveled by car, as compared with only 15 per cent in Japan.
