Traffic Flow survey

Extracts from this document...

Introduction

Methodology: Six methods were used to obtain results for the hypotheses. These will now be looked at in detail to determine whether these were the most sensible methods to use, or if they were unpractical and another method should have been used. Method One: Traffic Flow survey The above method was used to prove or disprove the hypothesis that stated that it was expected to find most cars in London, decreasingly followed by Aylsham and then Aldborough. This method was used because the results it offered would most prove or disprove the above hypothesis. The method was taken over a course of two minutes in each of the three locations, as it was felt that this was an appropriate time span. It was taken by one person standing for the two minutes on the same spot and counting the number of cars, lorries or any other form of transport that passed by, and recording the results in a tally form as they were standing by the roadside. This was a convenient, quick and simple way of obtaining the information we needed, and so it was regarded as quite a successful method. As some one physically stood in the field and collected the data, it is regarded as a primary source of data. Other methods could have been used to collect this data, though these were felt to be impractical and time consuming. An example of this is asking car dealers in the area for sales information, and then using this data. However, there is no certainty that the cars were driven in the specific area we were looking at, and also some of the cars may have been taken to other cities, towns or even countries, making any data we got from this source unreliable, time consuming and possibly confidential for the owners of the car dealership. It would also be irritating to the owners of the business to have lots of children asking for information, and would be likely to create an off putting environments for perspective buyers. ...read more.

However, with the questionnaire, there was more movement than there had been with the Traffic Flow survey. One had to move towards people rather than standing still and expecting people to go to them, as the traffic flow data had been collected by one standing in the same spot and counting the vehicles. This movement may have made the results a little unreliable as some of the people who were questioned were asked outside of the directly central market square, possibly down a side road or in a small corner shop, etc. Here is an example of the questionnaire sheet we used to collect data with: Method Three: Land Use Survey This method was used to prove or disprove the following hypothesis: "There will be a greater amount of and variety of shops in London, followed by Aylsham, followed by Aldborough" This method was used as it was thought to be the one most suited to the task of proving or disproving the above hypothesis. It was thought to be suitable as it displays the shops or buildings in a particular area, and can be made very specific if a detailed key is used. This therefore allows one to be very specific about the shops one sees in an area, which gives an accurate, clear picture of the services, shops and goods one could find in that area. This answers the hypothesis perfectly, and so was thought to be the right choice for proving or disproving the statement. This method was taken by one person sketching a rough map of the area whilst we were physically in the settlement, and labelling all the shops and buildings in that area. This drawing was then copied up once we got indoors and coloured in neatly according to the key. This makes the data primary data, as one standing physically in the field and physically collecting the data obtained it. ...read more.

Conclusion

This method was used because it was relevant to the hypothesis, and would clearly prove or disprove it. It was also used because it was the least time consuming and most convenient method available. The survey was done as a Primary source of data. Five different locations within each settlement were selected at random, and ten aspects of the different locations were observed. These aspects, such as litter and air pollution, helped to determine how clean the area was. Depending on the quality of the site, each aspect of the survey was graded out of 5 for the individual site. 5 was the highest number of points each site could get, and 1 was the lowest. Few limitations were offered by this survey, as it was well suited to the task of answering this specific hypothesis. However, when the five different locations were very close to one another, as in Aldborough where the area was not large enough to get sufficient distance between the locations, the results became very similar. In Aldborough itself, five locations were not necessary, when three could have displayed the same pattern with less inconvenience. I doubt that there was a more suitable method that could have been used to answer this hypothesis, as the environmental survey fully answered the hypothesis. The data was collected at three locations in each of the three settlements that were observed. In order to collect a large range, and therefore a larger picture, of results, three random and very distanced locations were chosen. In each settlement, one of these locations was in an area of the central location examined in each of the other surveys. The other two locations were selected at random, but were along the outskirts of the settlements. This offered a wider and broader picture of the area, and results are displayed as figures 1, 2 and 3 in radar diagram form. Here is an example of the Environmental Survey that was used collecting data in the field: ...read more.
