As time goes on, our society is developing. Inevitably, it has some advantages and shortcomings, including urbanization, that is towns and cities grow rapidly as people move from the countryside (Bilham-Boult, 1999). As is known to us all, urbanization causes a large quantity of problems. To solve these problems, governments have come up with a policy of sustainable development, which means development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland, 1987). From my perspective, sustainable development can largely solve the problems of urbanization, including easing traffic problems, reducing pollution and relieving housing pressure.
Easing traffic problems
With the social progress and economic development, more and more people have their own cars. Inevitably, traffic congestion become an important problem of urbanization.
In the late 19th century, railway companies made settlements around L.A. widely dispersed and this made the private car appealing. In 1925, the idea of underground railway was proposed, but county's voters rejected the idea. And the most serious problem is the growth rate of the amount of vehicles is faster than the population (Thisdell, 1993). This example shows Americans’ high reliance on their private cars, and it is so difficult to solve the traffic problem because the government has no efficient policy. If the governments pay more attention to the traffic infrastructure or change the city landscape may have certain help. Here is another example. Australian and Canadian cities' average increase in car use reduced from 1960s to 1980s. The reduced growth maybe due to 4 reasons: reurbanization of older suburbs; development of nodal subcentres in outer suburbs; better urban environments; less dispersion and development of highly car dependent cities (Newman, 1999). There is no doubt that Australia and Canada are developed countries and their nationals rely on automobiles much. However, they reduced the car use trends just because of the proper policy. These two examples show that the government’s intervention and the effective implementation of the policy are the guarantees of lightening traffic problems. So from this point of view, a policy of sustainable development can largely reduce the use of private cars.
The data of urban public transit in most cities is positive and “this reflects their cities’ overall plans and priorities to achieve this”. In detail, although the amount of transit in US is low, it's growing again. The growth in transit in European and Asian cities is accelerating. Such trends are positive for sustainable development (Newman, 1999). This example shows that more and more people have been reducing the dependence on private automobiles, as a result, the use of public transport has gradually grown. Fewer vehicles mean fewer traffic congestions, more walking and cycling, which is beneficial for...
