Like Dar es Salaam, many large cities face major transport challenges due to the continuous growth of the urban population, private vehicle ownership, congestion, and the fragility of public transportation systems. Transport can become a constraint on both economic growth and social development and inclusion, along with increased negative impacts on health and on the environment. Because of the increasing use of modern technology, transportation has become a data-rich industry. By bringing the data together, and by using open formats, the data can be used for innovative applications to help relieve urban traffic congestion, to improve the provision and operation of public transport services, and to reduce environmental damage with the goal of improving the lives of citizens. The use of data enables transport planners, operators, and users to obtain additional economic, social, and environmental benefits from the physical transport investment and infrastructure. This report shows that Dar es Salaam is on the cusp of a transport data revolution. Generally, the conclusions are that there are no major blocks to progress, but in many areas, there is a lot of work that will need to be done over time.
