The picture illustrates the number of trips taken by citizens via mass transportation in four cities of Australia, which comprises of Sydney, Melbourne, Brisbane, and Perth from 1900 to 2010.
Overall, it can be clearly seen that there is an upward trend in all regions mentioned. It is also noticeable that the trips amount in four cities rose steadily and remained their place over the period shown.
In 1900, Sydney started the period at 120 public transport trips per resident, which was constantly higher than figures for Melbourne with 100 trips, Brisbane with 60 trips, and Perth with 40 trips. In the following years, Sydney, Melbourne, and Brisbane witnessed a surge in the number of mass transport trips taken and peaked at nearly 350, 300, and 200 trips per person in 1940, respectively. While the figure for Perth just increased slightly to 50 trips per citizens in the same period.
During the next 40 years, people in Sydney, Melbourne, and Brisbane chose to commute by other types of transportation, resulting in a reduction in the number of trips taken per year to roughly 200 trips, 200 trips, and more than 100 trips per person, respectively. However, these figure rose steadily to 300, 250 and 200 trips per year, respectively. While the figure for Perth increased considerably and ended the period at 150 trips per citizen per year.
