The bar chart compares the number of passenger kilometres traveled by various forms of vehicles (bicycle, bike, ari, bus, and rail) in the UK in two periods (1990, and 2000). The units are measured in billions.
Overall, all the figures experienced an increase with the exception of bicycle and bike in the last time frame. At the end of the period, the total figure was by far the highest, whereas the reverse was true for three vehicles (bicycle, bike, and ari). Meanwhile, the rates for bus and rail were at about the same level.
In detail, the total number of passenger kilometres was 100 billion in 1990. Nevertheless, this rate considerably rose, reaching roughly 112.5 billion in 1990. As for bus and rail, which were the dominant categories among individuals, in the initial year, the former’s rate was approximately 40 billion, although the latter’s number was about just under 40 billion. Interestingly, both categories reached to the same level in 2000, at nearly 45 billion.
Regarding the rest of vehicles, which had the lowest rates, all of them (bicycle, bike, and ari) were just below 10 billion with some differences in the first period. Subsequently, the initial two modes of transport witnessed a decline, falling roughly 5 billion, though the number of the passenger kilometres by ari slightly grew to approximately 10 billion in 2000.
