The given chart illustrates the number of road automobiles registered in use in a European country from 1996 to 2006.
Overall, what stands out from the graph is that the number of buses declined, while private cars increased dramatically over the same period.
To begin with, the number of private cars rose significantly from approximately 20-21 million in 1996 to a peak of 24 million vehicles in 2006. Notably, private cars dominated the road vehicle market in both years.
In contrast, the number of buses showed a much lower count, reaching zero million in both years. Furthermore, the category of other types of vehicles saw a significant increase, rising to around 2 million in 1996. However, by 2006, the growth in other types of vehicles was marginal, reaching only 4 million.
Additionally, the number of lorries increased slightly in 1996, but by 2006, lorries had declined to zero million. Meanwhile, motorcycles also saw a slight increase in 1996, with around 0.3 million vehicles, but by 2006, this number had dipped considerably.
