The line graphs illustrate the proportion of people who used public transport and that who used private cars in the five Australian cities from 2000 to 2010. Overall, most cities had relatively stable figures in both type of transport, while Brisbane experienced a significant change in public transportation throughout the period. Of particular note, the patterns of Sydney and Melbourne were almost similar.
Focusing on the people using public transportation, in 2000, Melbourne and Sydney accounted for 18 percent and 20 percent, respectively. Afterwards, Melbourne stayed fairly steady except for a small dip between 2003 and 2005, and Sydney followed a similar pattern before gradually rising between 2007 and 2009. Brisbane first stood at 15 percent, which then grew to 25 percent until reaching a plateau, overtaking the other figures. Perth and Adelaide remained steady, hovering around the 10 percent and 5 percent, respectively over 10- years period.
However, Perth and Adealaide stood at 50 percent and 70 percent in 2000, which then markedly climbed to 60 percent and 90 percent, respectively, at the end. By the end of the period, Brisbane slowly soared from 40 percent to 50 percent. Sydney and Melbourne saw small fluctuations between 20 percent and 40 and between 30 percent and 20 percent, respectively.
