The evaluation of economic and environmental sustainability and coordination of financing proposals complete the picture of the actions identified by the project InterAlpes for the development of intermodal transport between Italy and France.

From the economic point of view, were considered the costs budgeted for each action identified, compared to comparable initiatives and, in any case, corresponding to the information provided by the stakeholders, the Community principles and any references benchmark in similar contexts of transalpine routes.

A technical evaluation of the railway line has supported the analysis of individual stocks, examining the conditioning elements (such as train length, weight, different needs of railway traction, etc..) And the elements of organizational-management: the profitability of each share has been calculated on a defined time horizon and through a measurement variable (the ton, the intermodal loading unit ICU, or the single vehicle), assuming that, downstream of the development process of the service, the transport company to apply to potential clients with a uniform tariff, capable of expressing the full-cost of the service, as well as the differences with the method of road transport. The subsequent identification of the so-called "break-even load factor" then allowed to quantify the volume of traffic required to repay the cost of the rail service at market prices, compared to its main competitor, namely road transport.
The environmental assessments conducted under InterAlpes have been applied to the different phases of the project and, in particular, actions, comparing the two alternative hypotheses of transport: all-road and intermodal, assessing its environmental effects in terms of fuel consumption and emissions . The environmental assessments carried out are developed, specifically, in relation to changes in pollutants emitted depending on the assumed traffic scenarios, allowing you to consider the benefits in terms of lower emissions than any case of modal split. Air pollution is estimated by the application of some recent models of hot emission (those models CORINAIR-Commute), developed within the European project Commute, which consider the main source of vehicular pollutants (CO, CO2, NOx, NMHC , VOCs, benzene, PM, PM10). Other elements considered in the model for the characterization of transport, such as the average travel speed in the examination and the breakdown of the vehicular fleet in types (capacity, age, type of power).
The results of the models are basically "emission factors" and "factors of consumption", expressed generally based on the distance traveled, which allow to quantify the amount of pollutant emitted at the exhaust and the amount of fuel consumed by a vehicle of known characteristics, to vary the speed.

The analyzes were performed both at a global level, by calculating the total amounts of pollutants emitted over the entire study area, both locally, by examining issues related to the area that houses the main receptors, particularly in areas subject to environmental protection.

The results for these processes have allowed us to evaluate the positive effects in terms of the environment for each action identified by the project InterAlpes and calibrate the appropriate modal shift from road to rail.
The evaluation of the operating conditions of the proposed actions, finally, provides for the establishment of a joint action plan on the coordination of proposals for financing from European funds (TEN-T), national and local infrastructure and identification of any institutional body with the task of promoting and operational coordination.
