There are 7 main forms of transportation used in South Africa: personal cars, walking, bicycles, horse-drawn carts, buses, taxi vans, and trains. Public transportation is important because unemployment is high at 40% and many cannot afford personal vehicles. The most common forms of public transportation are minibus taxis, which provide flexible routes but can be unsafe, and trains, which 15% of commuters use daily. Buses account for 22% of public transportation use. New BRT systems are being implemented to provide safer alternatives to minibus taxis.
