Transportation problems in Indonesia, particularly in big cities such as Jakarta, Surabaya, Semarang, Bandung, Makassar and Medan, undoubtedly lie in the dominance of private vehicles, both cars and motorbikes, and in the limited number of mass public transportation available. In Jakarta, for instance, mass public transportation accounts for only 2 percent of a total of 9 million vehicles, and the rest are private vehicles. This overwhelming number of private cars and motorbikes causes traffic congestion in Jakarta.
