The pie charts illustrate the proportions of people using various forms of transport to travel to a university for work or study in 2004 and 2009.
Overall, there was a marked decline in reliance on private cars over the period, accompanied by substantial growth in the use of buses and bicycles. By 2009, public transport had overtaken cars as the most common way of commuting to the university.
In 2004, just over half of commuters travelled by car, accounting for 51% of all journeys. Bus travel was the second most popular option at 33%. In comparison, far fewer people used bicycles (9%) or trains (3%), while walking was chosen by only a small minority, at 4%.
Five years later, the distribution had shifted considerably. The share of car users dropped dramatically to 28%, whereas bus travel rose sharply to 46%, becoming the dominant mode of transport. Cycling also experienced notable growth, increasing to 16%. Meanwhile, walking saw a modest rise to 6%, and train use remained relatively stable at around 4%.
Overall, the data suggest a clear movement towards more environmentally friendly transport choices among university commuters between 2004 and 2009.
