Traffic congestion is a problem occuring in major cities in developed and developing countries. In terms of car ownership, Australia is ranked 7th globally with 717 cars per 1000 people. While Brazil is ranked 61st globally with 215 per 1000 (in 2014). Peak hour traffic in Australia is the commute to and from work. In Brazil peak hour traffic is to and from work, aswell as the midday lunch and school pick up. As cars become more attainable for more people in Brazil and ownership rates rise, if ownership rates grow equal to Australia, with the transport infrastructure system already very strained in Brazil the outcome will not be good unless interventions occur. Pictured is midday traffic here in Salvador , theres no accident, no holiday, no big sport match, no rain and no police checkpoint ..... just midday traffic build up.
