intermodal solutions for transalpine freight traffic - Alpine Space ...

The calculation of the itinerary and the air
pollutant emissions is based on the bare connection
between the involved intermodal platforms.
To make the calculations more transparent
it has been decided not to consider pre- and
on-carriage to/from the intermodal terminals in
the calculation.
The T.Env modelling tool allows the evalution
of the existing and foreseen road and rail traffic
flows (freight and passengers), both in relation
to the implementation of new pilot projects and
for the considered transport system in different
conditions (development scenarios).
For this reason. the concrete advantage of
the chosen modelling architecture is the strict
linkage between the evaluation of the functional
effects of transport and its impacts (expressed
in terms of estimation of emissions).
The starting point was an estimation of the
flows on the network, aiming at defining potential
increases and/or decreases of the pollutants
produced by the vehicle flows in the
road/rail network. This is consistent with what
is foreseen by the metodology of the modeling
assignment and distribution and also considers
the scenarios of reference and simulates the
emissions from vehiclae traffic.
Inputs for this emission evaluation model are
the results produced by the model of transport
simulation, specifically built and implemented
for the representation of the road and rail traffic
flows (freight and passengers) within the Alpine
Space.
In the case of mountainous regions (such
as the Alps), T-Env allows evaluating potential
benefits on the air quality. This special feature
is derived from the shift of road freight traffic to
the new rail connections for combined freight
transport. Its link to a specific management
software facilitating the interaction of the users
(interactive graphics) allows evaluating both
the functional and environmental performances
of the single systems of the transport network
including the selected Pilot Project.
Both the present situation and the scenarios
of future development made as a reference allow
simulating the mobility of freight vehicles
within the studied area.
The transportation model simulates both
private and commercial vehicles. They are implemented
by means of road and rail graphs
on the existing and the foreseen network. This
allows a plausibile analysis of the actual condition
on the road and rail network.
