Abstract :
[en] External costs have been a key issue in the last years of transport
research. In Europe, this trend is in line with the political willingness
to internalize externalities in transport pricing policies. This paper
has two purposes. It first identifies the recent work achieved in the
field of external costs of road and intermodal freight transport,
where each paper is assessed in terms of its perspective (academic
or project oriented), its objective (prescription, application,
projection), the type of externality (air pollution, climate change,
noise, accidents, congestion) and the type of cost (marginal,
average, total) that is considered. The literature review reveals a
gap in the development of generic mathematical functions for
external costs of transport. The second objective of the paper is
thus to highlight the usefulness of such functions by identifying the
main parameters that influence freight transport competitiveness
in terms of external costs, and by determining which of these
parameters should be incorporated in further research works.
