The bar chart details the number of passenger kilometers covered by various modes of transportation in the UK in two years 1990 and 2000. The initial impression from the chart is that very few kilometers were travelled using bicycles, motobikes and planes compared to buses and trains. It is also clear that whilst traveling by air, bus, train and in total enjoyed upswings, the opposite was true for bicycle and motorbike. In 1990, bicycles and motobikes were not used much in the UK, at only around 5 billion passenger kilometers, and the figures even went down to 4 billion over the next 10 years.Also standing at the relatively low of 5 billion in 1990, aviation travel thereafter rose, albeit slightly, to roughly 8 billion in 2000. Opposite patterns are evident in bus and train travel. Both started at a high of 42 billion and 40 billion (in that order) in 1990, and then rose to 50 billion in 2000. The total figure also grew from 100 billion to 110 billion over the same time frame.
