In-depth studies have been carried out
for the ten multi-modal pan-European
corridors that form the backbone of
the network adopted in the transport
infrastructure needs assessment (TINA)
process. Results have suggested that it is
important to support multi-modal
solutions, while at the same time paying
attention to positive boundary conditions,
including intermodality and patterns of
inter-regional co-operation.
Combinations of road and rail projects
were generally found to offer the greatest
benefits, with road projects bringing
greatest benefits in terms of accessibility
and rail projects in terms of safety
improvement and air pollution reduction.
Diversification of the investment in
different types of infrastructure was also
found to have greater success in achieving
national transport policy objectives.
