Monetary values of transport service attributes: land versus maritime ro-ro transport. An application using adaptive stated preferences

The objective of this work is that of illustrating a methodology to derive, in terms trade-offs, the relative values of transport service attributes for logistics . In particular, the analysis yields insights on the preferences for timesavings, and reliability of the transport service in terms of price, of a of freight forwarders located in the South of Italy. The data is gathered an Adaptive Stated Preference application and the estimates are obtained a Tobit ML estimator on both company specific data and pooled data. results show that frequency is the most highly rated characteristic of the together with reliability. The value of time is significantly lower in both . The outcome is consistent across estimations and, substantially in line with outcome of previous studies carried out on operators active at different levels the transport-logistic chain. Until now, in fact, studies have been carried out on carriers or producers. The selection of freight forwarders allows to light on a segment of the market that accounts for more than half of the -related decisions. Furthermore, the present study focuses on a between all land transport and maritime ro-ro alternatives, in line the growing interest on the integration among transport modes. The output both the absence of any a priori preclusion for ro-ro maritime services and extremely important role that frequency of service assumes for the and the establishment of maritime services as realistic alternatives all land transport.
