With extraordinary levels of demand for public transport in its cities, Africa is an exciting place to develop new transit systems. Catering for such demand brings its own challenges, particularly at an operational level in providing the necessary capacity to satisfy travel movements. Bus-based systems can meet the levels of demand through the provision of high bus frequency and dedicated infrastructure. However, as the frequency of operations increases, greater stress is placed on the operating infrastructure and system management. With lower tolerance to disruption, careful design and planning is required to ensure that the system operates efficiently not only in perfect conditions where all elements run as planned, but can cope when things don’t run as smoothly. The transit system design process must ensure that the infrastructure, service plan and operational management work together to ensure efficient operations in the conditions within which the system must operate. This paper looks at how microsimulation can serve as a valuable tool by testing the system design under the inherent dayto- day variability affecting operations.
