The paper analyses the competitiveness aspect of Italian domestic traffic in its main component of road, combined maritime transport and combined railways transport of trailers. They are essentially the first results of a research granted by Italian Research Ministry. Preliminarily it has been determined the more relevant links of sending at province level in all territory involved in the analysis. It has been possible to apply the econometric analysis based on McFadden RUM methodology. In this context was tested an application of a long distance model by a disaggregate-aggregate approach. At local level a previous stated preference survey on shipper sending goods at regional level was available. On the contrary the acquisition of the database for all domestic modes has been complex especially in relation to intermodality. This has required the use of aggregated data especially for short sea shipping and combined railways analysis. Data derive in these cases from the port authorities and from the Railways Cargo Division. Finally the impact of a price reduction on maritime combined transport on demand modal split by the probabilistic arc elasticity was evaluated. Different scenarios defined by a price reduction of sea-road combined and railways-road combined freight were considered. The necessity to limit drastically the road traffic along the motorways by using the two maritime links of Adriatic and Tyrrhenian sea is presented. For the covering abstract see ITRD E126595.
