Abstract: For ten years, the investment decisions in urban public transport have been occurring in an environment which faces an increasing uncertainty. The financial crisis, the appearance of new technologies and the apparent failure of economic appraisals have caused a real "decision crisis". In front of this rise of uncertainties, decision-makers are obviously displaying a preference for flexibility in the field of transport choices in urban areas. Indeed, they give greater importance to choices that provide the widest range of options for the future. Meanwhile, the irreversibility theories have experienced important developments, enabling economists to meet with the needs of decision-makers. The aim of this work is to suggest a methodology to compare levels of flexibility for alternative technical options in the well-known Cost-Benefit Analysis. The conception of a decision-taking model for transit should allow to estimate relative levels of risk, and especially to introduce the "irreversibility effect" as a part of socio-economic return. Simulations will be carried out, based on simple case studies in the field of public transport.
