Task 1: The pie charts provided illustrate two major changes in the use of modes of transport to a certain university between 2004 and 2009.
In the first place, the use of the car was the only one that had a downward trend, from 51% in 2004 to 28% in 2009 (a 23% decrease). This probably resulted from the fact that car parking began to be charged in the university in 2006. In contrast, travelling by using all the other means of transport had an upward trend. The most remarkable changes were in the use of the bus and the bicycle: a 13% and 7% rise respectively. One of the reasons was perhaps the year 2008 witnessed the appearance of a new bus stop in the university. The remaining two methods of transport also rose but insignificantly: by 2% (walking) and by 1% (train) only.
Overall, there were two contrasting trends of travelling to the university in the five-year period concerned.
