The pie charts illustrate the changes in transportation methods used by students and staff at a university for academic purposes and work between two specific years: 2004 and 2009.
Overall, the data shows commuting habits over a five-year period. There was a notable decline in private vehicles, while the use of public transportation and more sustainable options, such as cycling and walking experienced a rise. This suggests that campus policies or infrastructure have influenced travel behavior.
In 2004, the car was the preferred method for travel, accounting for 51%. The bus was the next common choice at 33%. Other travel methods were less popular, such as bicycles at 9%, walking at 4%, and trains at the lowest proportion, with just 3%.
By 2009, the statistics of transportation had totally changed. Car usage fell to 28%. Conversely, bus travel became the new majority preference, going up to 46% of commuters. Cycling nearly doubled its share to 16%. While walking and train use also saw modest increases to 6% and 4%.
