Modelling mode choice for freight transport using advanced choice experiments
2015
Abstract In this paper we use advanced choice modelling techniques to analyse demand for freight transport in a context of modal choice. To this end, a stated preference (SP) survey was conducted in order to estimate freight shipper preferences for the main attributes that define the service offered by the different transport modes. From a methodological point of view, we focus on two critical issues in the construction of efficient choice experiments. Firstly, in obtaining good quality prior information about the parameters; and secondly, in the improved quality of the experimental data by tailoring a specific efficient design for every respondent in the sample. With these data, different …
Triggering collective action for bio-energy supply chain through contract schemes
2016
This paper discusses contractual features to manage and coordinate a hypothetical bio-energy supply chain. The present study focuses on farmers operating in two Regions of Italy, namely Sicily and Campania, somewhat representative of areas with high potential of investments in new bioenergy supply value chain. Farmers were asked to choose whether to participate or not in a collective investment regulated by contract schemes. Monetary trade-offs were then computed among contract attributes. A specific questionnaire was submitted to a sample of farmers selected on the basis of their potential capability of investments. A stated preference modelling approach was implemented so that farmers cou…
The potential of rotorcraft for intercity passenger transport
2007
Abstract There are many high-speed rail projects in Europe at different stages of development. They are supported on environmental grounds and as a means of reducing congestion on other modes, including aviation. High-speed rail, however requires major investment costs, takes a long time to come online, and involves considerable financial risks. A potential alternative that overcomes some of these problems makes use of rotorcrafts. This paper assesses the potentiality of civil rotorcrafts as part of the air transport system. Discrete mode choice models are used to forecast traveller choice behaviour when the rotorcraft is introduced and financial evaluations performed looking at the operati…
