The bar chart compares the total number of passenger kilometers travelled (in billions) by five different modes of transport in the UK in the years 1990 and 2000.
Overall, while all means of transport experienced growth in passenger travel over the decade, buses and railways remained the dominant forms of transportation, with air travel seeing the most notable relative increase. The total distance travelled by passengers also rose significantly.
In detail, buses accounted for the highest number of passenger kilometers in both years, rising modestly from around 50 billion in 1990 to approximately 55 billion in 2000. Rail travel followed a similar trend, increasing from roughly 40 billion to nearly 50 billion passenger kilometers. Air transport, while starting from a lower base at about 10 billion in 1990, more than doubled by 2000, highlighting its growing popularity.
Meanwhile, motorbikes and bicycles represented the least-used transport modes. Motorbike travel grew slightly from just under 10 billion to around 12 billion, whereas bicycles saw a more modest rise, from about 5 billion to 7 billion kilometers. The cumulative total of all transport types climbed from approximately 105 billion to nearly 120 billion passenger kilometers, indicating a general upward trend in travel activity across the UK during the period.
