Abstract (EN)

People see and evaluate risks in a very different way, this is probably the most changeable variable that we must take into account developing some public policy on risk. People's judgements depend on both their personal experiences and from the context in which they are, thus, these conditions make impossible to evaluate them a priori. In this paper we present a French real case on transport infrastructure and risk management, namely the safety of their users. The aim of this paper is to provide, on the one side, an example of public policy management in which people safety and economic constraints are involved. And on the other side, open a discussion about risk reduction and the policies achieving it.
