The choices of mobility are characterized not only by the costs of the different means of transport, from large external costs, which are not the user but by society, or on a part of it. The case of the costs associated with air pollution, noise, congestion, accidents and related health care costs, and finally the release of greenhouse gases blamed for global warming.
