In contrast to point-to-point, a Hub-and-spoke network allows consolidation of traffic flow at some special demand points, hubs, before reaching their destinations. This makes it economically more viable, through economies of scale mainly where travel demands are dispersed or uncertain. It also provides demand coverage within the network and facilitates transportation conditions and access to services. Hence, there are many applications of hub concept to transportation, telecommunication, logistics, etc. However, among them, public transport received least amount of attention. This work investigates the potential of hub network for public transportation planning in sparse travel and low network density conditions of Bamako. We first diagnose the major current issues and future challenges of public transportation planning. We then derive the projection for Bamako following its long term development vision. Estimation of travel demand completes the later in order to confirm the existence of indices for hub application to transportation planning within Bamako. Then, we propose a typology of the potential hub network, star one, based on its advantage. Finally, we present the benefits of such structure for both transit and urban system.
