In the present day, even though the Taiwanese Government has several plans to improve conditions of urbanization, the cities still confront various challenges. In the case of Taiwan, we are faced with high density causing traffic problems, although local governments have built public transportation (for example, the MRT) as an essential tool, and advocate citizens using vehicles less. However, people have to spend more time in the rush hour just because of living in high density residential areas. In the matter of economy, crowding of residents in the same area will increase the costs of public installations rather than bring about effective economic growth. Additionally, there will be financial issues; vast areas that speed up the development process and it do not conform to market needs. Beyond that, there are difficulties altering habits of residents. The local inhabitants have ingrained notions about land use. Hence, community development lags.
In general, Government lacks continuous monitoring, and the related development departments need to form a common view of collaboration in order to set up rules of maintenance. In this respect, as often in plans of community empowerment few successful illustrations can be found. Most plans are paused due to lack of better institutions and management. Also, public opinion is a very important factor in strategic decisions of design, and the conflict between public and private realm benefit is the key point in negotiations with the public.
New urbanism is based on the principle of blending community uses. In Taiwan, there is no clear demarcation between residential areas and commercial sites. The commercial activities follow the edge of main roads and became a strip of spatial use. There is a case in Kaohshiung in southern Taiwan, and the plan of zoning controls is related to road most places that are thought of as commercial areas actually are residential districts. This condition leads to public facilities and services that cannot bear the excess population.
According to “Spatial-temporal changes of regional sustainability: an empirical study in Taiwan” by Y.-T. Hung and K.-W. Tsou. (2006, 245) nine factors affect regional sustainability. The most important emphasis is on the use of non-renewable resources including electricity and automobiles. As has been pointed out, urbanization causes rural people to migrate to the metropolis and this situation results in large resource consumption in the same area. The environmental consciousness must be imbued into people and also Government must promote renewable resource use.
In addition, the crime rate is increasing in Taiwan, owing to rapid urban development which changes residential living habits and also reduces the relationship between residents. People can not control the residency of their surroundings; this causes a sense of insecurity. Inhabitants care for themselves but do not regard the public environment as a safe place. As can be seen, several high-rise buildings must have security service personnel and closed circuit television.
