The two pie charts illustrate the primary methods of transport used by people traveling to a university in 2004 and 2009.
Overall, the percentage of individuals commuting by car fell dramatically over the five-year period, while bus and bicycle usage experienced significant growth. Walking and train usage remained relatively unchanged.
In 2004, cars were the most popular mode of transportation, accounting for 51% of all trips. However, by 2009, this figure had plummeted to 28%, a notable decline. In contrast, the percentage of people using the bus rose considerably, from 33% in 2004 to 46% in 2009, making it the most commonly used mode of transport in the later year.
Similarly, the proportion of bicycle users almost doubled, increasing from 9% to 16%. Meanwhile, the number of commuters who traveled by train showed a slight rise, from 3% to 4%. The percentage of those who preferred walking remained unchanged at 4% over the five-year period.
The data suggests that changes such as car parking charges in 2006 and the introduction of a new bus stop in 2008 may have contributed to the decrease in car use and the corresponding increase in bus travel.
