Transport Competition on a Multimodal Corridor by Elasticity Evaluation
M Catalani, University of Naples "Parthenope", IT
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. Successfully it has been possible to apply the econometric analysis based on McFadden RUM methodology .In this contest it has been tested an application of a long distance model by a disaggregate-aggregate approach. At local level it was available a previous SP survey on shipper sending goods at regional level. On the contrary the acquisition of the data base for all domestic modes has been complex for the presence of relevant aspect of intermodality. That has required the use of aggregated data especially for short sea shipping and combined railways analysis. Data derive in these cases by the port authorities and by the Railways Cargo Division. At last it has been considered the impact of a price reduction on maritime combined transport on demand modal split by the probabilistic arc elasticity. Particularly has been analyzed different scenarios defined by a price reduction of sea-road combined and railways-road combined respectively. We are really in front of the necessity to limit drastically the road traffic along the motorways by using the two maritime links of Adriatic and Tyrrhenian sea.
