How useful are urban models to the modern geographer and urban planners?

An urban fabric is a reduction of a real metropolis. They be apply to help us visit more about real cities by showing patterns or processes which in real life may be complex and difficult to identify. They are applicable to a large number of cities rather than whiz exceptional city. They are establish on the idea that there are similarities between cities.Geographers custom these mildews to try and identify and explain urban spatial patterns and variations in their structure. Where as urban devisers use the gravels to deal with real life situations such(prenominal) as deciding where to place a fresh motorway or deciding where to build a new business park.The first urban exercise to be produced was by Burgess in 1924 he attempt to explain the outward expansion of the city (Chicago) and the socioeconomic groupings of it inhabitants. He did this by splitting the city into five concentric zones the central business district, changeover zone, low year living accommodations , medium class housing and high class housing. He devised these zones by the theory that individual compete with each other for the most favourable locations within the city. This competition was founded on the market for buildings and chicaneledge base those who can afford the highest prices will get the best and most favourable land.This model could be effective to modern geographers as it could be apply as a good starting point to look at the spatial variations of sections/zones within a town. It could too help to explain why people prevail where they do and why they live in original groups.This model could be useful to modern urban planners as it could be used to describe the existing patterns of land use or city morphology and be compared to that of the modern morphology of a city in deciding where to place a received building etc. receivable to the density of inhabitants in a original area. It could also be used to measure land values and density within a city.Hoyt was the trice producer of an urban model in 1939. He adapted on the same implicit assumptions that burgher had made but with adaptations. Hoyts model was based on the mapping of eight housing variables for 142 cities in the USA. He act to account for changes in, and the distribution of residential patterns. He had the addition of three new factors on the burgess model. He suggested that areas of the highest rent tended to be alongside master(prenominal) lines of communication and that the city grew in a series of wedges. He also express that once an area had developed a land use that it would uphold that use as the city extended outwards.This model could be useful to modern geographers as it is a better adaptation of the burgess model. Meaning that extra factors look at been taken into consideration such as the wealth and similar land uses. This could be more helpful as it makes more judgements on where and why variations will happen. Such as loaded people can afford the hig hest rates so will have the best position and afford to buy cars so will live further from he Central business district.This model could be useful to modern urban planners as it is a better adaptation of the burgees model with extra factors taken into consideration. This could be helpful to a planner as it talks about land value and how similar land uses allure other similar land uses. This is helpful as a planner can come on where certain industries are and where to situate them. Also to know where the wealthy people are will help to know what function and transport routes are best targeted towards themMann was the third producer of an urban model in 1965. He tried to adapt the Burgess and Hoyt models to three industrial towns in northern England. He made a compromise model that combined ideas of burgess concentric zone model with that of Hoyts sectors model. He untrue that because of prevailing winds in northern Britain blow from the west, that the high class housing would be in the west and industry with its smoke, would be locate to the atomic number 99 of the central business district.This model could be useful to modern geographers as it combines the two theories of Hoyt and burgees resulting in a more complex and relevant model. It could be useful to see if industry does affect the position and distance of certain types of economic wealth.This model could be useful to modern urban planners as it combines the theories of Hoyt and burgees producing a more complex and applicable model. It could be useful in the location of industry and the construction of houses for different socio economic inhabitants.Ullman and Harris were the fourth producers of an urban model in 1945. They set out to produce a existent model compared to those of Burgess and Hoyt but consequently they ended up with one that was more complex and this meant that the model was more descriptive then predictive. They said that a quadruple nuclei needed to be developed as a response to the need for maximum accessibility to a centre, to keep certain types of land use apart and to show differences of land values,This model could be useful to modern geographers as it is more realistic to the modern realness with its complexity. It could be useful to see if a town/city does truly follow the model with several nuclei. It also help to explain the inhabitants that permute to the central business district and see if they add to its density and population.This model could be useful to modern urban planners as it could help to locate bus routes and roads that were needed for the commuters and people who travel to work from the multiple nuclei. It could also help in the planning and placing of new houses for the people leave the city to commute to work.In conclusion I think that urban models are very useful to modern geographers and planners .I think that models are a good starting point for analysing the morphology of modern cities. These models were produced in the p revious(prenominal) so it is obvious that changes will have taken place such as technology, fashions and transport. This does not mean that the models cannot be of use. The principles can still remain with a little adaptation to the real modern world.
