Transport infrastructure in Brazil is characterized by strong regional differences and lack of development of the national rail network.[1] Brazil's fast-growing economy, and especially the growth in exports, will place increasing demands on the transport networks.[2] However, sizeable new investments that are expected to address some of the issues are either planned or in progress.[2][3] It is common to travel domestically by air because the price is low.[4] Brazil has the second highest number of airports in the world, after the USA.[5]
