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