In Tanzania, all privately owned vehicles providing public transport services are known as daladalas. 1 Legal since 1983 (see Chapter 2), these unscheduled services carry approximately 98 per cent of public transport passengers in Dar es Salaam (approximately 1.4 million passengers per day)(Mengesha et al. 2002; JICA 2008). The only bus company in Dar es Salaam is Shirika la Usafiri Dar es Salaam (UDA), 2 which provides for the small remainder of passengers.
