The line graphs show the percentage of people using public transport and people using private cars in five cities of Australia over 10 years from 2000 to 2010.
Overall, it is evident that private car usage increased significantly over 10 years in Sydney, Perth, Adelaide, Canberra, and Melbourne. The five cities in Australia consistently showed the highest private car usage rate, while public transport users do not increase like private car users, although the cities of Adelaide and Canberra do not decline drastically.
Public transport users from Sydney, Perth, and Melborne once increased but in the end it also went down, not like Adelaide which had decreased from 12 to 10 and increased again to 12 people. Canberra increased too from 10 to eleven people, not much changed, but increased and there was no decrease.
In contrast, private car usage increased consistently from 2000 to 2010, it means people who used private car in Australia not decreased over 10 years.
