The line graph illustrates how many passengers used different vehicle modes between1952-2002 in Great Britain. Overall, the number of car passengers had been dramatically increasing, meanwhile people who tend to travel by buses and coaches slightly dropped. As for the railway passengers, they had remained the same over the time period. Firstly, the disparity between passengers of car and buses, coaches was a little in 1952 (about 50 billion people), however over the time people who preferred car were increased. Furthermore it seems that the highest point for latter category is approximately 650 billion people in 2002. As for the busses and coaches, usage of this transport mode was slipped to the around 50 billion people, which became equal with railway passengers in that year. But it needs to be mentioned that latter transport type has a figure which had not been changed by 2002 and accounted for roughly the same amount of people over the period.
