Significance Of Urban Sprawl In The Subway

In general, location selection of modern city subway takes on the following features.

Firstly, large passenger flow and complex traffics. Usually, the number of passengers should be large enough to fulfill at least half a train once at certain busy times and the demand for transport is big too. The set of station location should not only satisfy the demand for interchanging for passengers, but also coordinate with other traffic lines and various transfer modes to guarantee the high safety. One universal rule is that the locations must assure that passengers could use walking to reach stations from wherever starting location or other transportations.

Secondly, the intensity of exploitation, construction and development is great. For subway

Urban sprawl is often evaluated and characterized exclusively based on major socioeconomic indicators. They mainly include this following ones: rise in standard of living, improved infrastructure, lower land rates, increasing population, lack of urban planning and consumer preference. These factors are inter-related and could lead to each other by bidirectional way. Usually, after any business potential which could be found in certain region, human must go and try their best to tap the potential out and convert it into tangible capital and cash. After enough accumulation of funds, the local government is able to repair and add necessary infrastructure and facilities. Plus, not too high prices of land, more people are willing to closely follow the movements and trend of certain areas. As population size increases, so does the amount of land required for residential and commercial needs. Population growth is the most significant factor effecting urban sprawl because it could be either a source or result as a key link then all factors assemble a full

Absolute identification of sprawl is never possible with these measures unless we define a lower limit towards the distinct characterization of whether it is sprawling or not sprawling. However, defining a threshold is not an easy task. Researchers have made their own assumptions towards defining this threshold, which are even less clear to the scientists and even citizens. Important to realize that relative measures of sprawl or measures of urban growth pattern fail to draw conclusion on sprawl at most times and cannot be used universally. These measures may help to prove or strengthen the scientific purposes well, but never can become a technology; because to interpret the results one has to be a scientist. Therefore, how these techniques can become a tool for a city administrator is an obvious
