Reliability Assessment of the Transport System, Addis Ababa Case Study

Abstract The subject of the article is the method of assessing the reliability of the transport system on the example of Addis Ababa in Ethiopia. The transport system and its technical condition, transport infrastructure, organization of the transport system, environment (users, environmental and climatic conditions), and legal provisions, have a significant impact on the reliability of the transport system. The most common means of transport in Addis Ababa is a car (including: taxis and minibuses). An important problem in public transport is the long waiting time for the vehicles, resulting from random events accompanying transportation processes in a defined infrastructure with limited resources. The article presents also the concept of a transport system availability model for developing countries on the example of Addis Ababa in Ethiopia.
