The given pie charts illustrate five main different methods of transport-namely car, bicycle, bus, train, and walking- used by people to travel to one university between 2004 and 2009.
Overall, it is obvious that cars showed a downward trend, while the reverse was true for the other remaining categories. Notably, throughout the period, buses witnessed the most significant increase and surpassed cars to become the dominant leader, while cars saw the most noticeable fall. Furthermore, there were car parking charges in the university in 2006 and a new bus stop in the university in 2008.
Regarding the methods that experienced upward trajectories, in 2004, buses ranked second at 33%, which was nearly triple the proportion of bicycles at 9%. Afterwards, in 2009, the former surged to 46% and overtook cars to account for the largest proportion, while the latter recorded a 7-percentage-point increase. Meanwhile, in 2004, trains and walking figures stood at 3% and 4%, respectively, before growing gradually to 4% and 6% at the end of the timeframe.
In stark contrast, in 2004, it was reported that cars constituted 51% of the total, making this category the most common method. Finally, at the end of the given period, this percentage dropped to 28% and became the second highest.
