Analysing the quality of life in urban environment in the context of providing traffic capacities, presents a universal and a multi layered problem. It is often the case that the public transport systems or parts thereof are not used optimally. During peak loads, crowds decrease comfort, while empty rides make many services financially unprofitable. Traffic generates loss of public areas, since the increase of the traffic demand decreases social activity and obstructs traffic networks. Moreover, pollution and noise have a serious impact on the quality of life and health, with pronounced political and media campaign. The Town of Rijeka, with gravitating settlements in the suburbs, is an example of overpopulated urban structure with almost permanent peak load. The existing traffic difficulties in the inner town area arise from the inappropriate ratio between the capacities of the existing roads, and the amount of traffic (both individual and public). The existing bus transport modality is the result of the selection made years ago, although the world and European trends point out to the need for technological innovations.
