The provided pie charts illustrate the various modes of transportation employed by individuals commuting to a university for work or study in the UK during the years 2004 and 2009.
A salient observation from the data is the substantial shift in preferable transport choices over the five-year span, notably with a decline in car usage and a corresponding rise in bus and bicycle travel.
In 2004, the predominant mode of transportation was the car, selected by 51% of the commuting population, thus accounting for over half of all travelers. The bus was the second most utilized option, with 33% of individuals opting for this method. In stark contrast, alternative transportation modes such as cycling, walking, and train travel were considerably less popular, comprising only 9%, 4%, and 3% of the total, respectively. This indicates a strong preference for personal vehicles and buses during this period.
By 2009, a notable transformation had occurred. The bus emerged as the preferred mode of transportation, with its usage surging by 13 percentage points to reach 46%. Meanwhile, car usage experienced a significant decline, dropping to 28%. The bicycle gained traction as a viable alternative, rising to 16%, thereby securing the third spot in terms of popularity. Moreover, there was a modest increase in the number of individuals choosing to walk or take the train, with proportions climbing to 6% and 4%, respectively. This trend reflects a broader shift towards sustainable and varied modes of transport among commuters.
