This article focuses on free fare public transport policy (FFPT) as an example of the sustainable mobility paradigm FFPT is one of a number of instruments through which a balance between the economic costs and efficiency in the public transport system can be reached. Even though the strategic approach of FFPT systems is used worldwide, their implementation is somewhat sporadic. By investigating examples of currently or formerly existing free fare public transport schemes, this study analyses the overall ability of FFPT to reach the strategic targets required. The study identifies four key areas that the municipalities are trying to target (reducing car use externalities, social justice/benefits provision, increasing the efficiency of public transport, and promoting sustainable means of transportation). As the specific conditions of each locality generate particular issues, the strategy of each transport system authority differs from one to another. It is, therefore, necessary for the transport planning authorities to implement various tools (both supportive and repressive) whose synergies will target the main objectives. A systematic and conceptual approach is what underpins the successful development of the urban transport system in the long-term.
