Rio de Janeiro
Driving in Rio de Janeiro, as in most large cities of Brazil, might not be the best choice because of the large car fleet. The city is served by a number of expressways, like Linha Vermelha, Linha Amarela, Avenida Brasil, Avenida das Américas and Avenida Infante Dom Henrique (Aterro do Flamengo); in spite of this, traffic jams are very common. Because of the organization of the 2016 Olympics the city is installing four BRT systems to link Barra da Tijuca with other major neighbourhoods: TransOlimpica (between Barra and Deodoro); TransBrasil (over the Avenida Brasil expressway); TransCarioca (between Barra and the Galeão International Airport); and TransOeste (between Barra and Santa Cruz, over Avenida das Américas).
