The pie charts provided illustrate the percentage of five different modes of transportation people utilized to commute to a university in 2004 and 2009.
Overall, it is discernible from the charts that cars were the only means of transportation that saw a decline, while a reverse trend was seen in other types. Additionally, cars were the most popular mode of transport in 2004, but in 2009, buses dominated the statistics.
Looking first at those with the most significant changes, automobiles were the predominant means of transportation in 2004, with the figure being 51%, followed by a nearly twofold decrease to only 28% after 4 years, ranking second/falling to the second position. Conversely, the share of people opting for a bus to go to the university started at second place, standing at 33%, after which it soared to 46% to take the lead in 2009. A similar trend, albeit to a lesser extent, was also observed in the figure for people cycling to the school, which rose dramatically from 9% to 16% over the period. Notably, there was a growing trend toward more environmentally friendly modes of transport.
Turning finally to the other two ways of traveling which were walking and taking a train, both saw some marginal increases, reaching 6% and 4% at the end, respectively.
