This research effort develops a national freight mode choice model employing data from the 2012 Commodity Flow Survey (CFS). While several research efforts have developed mode choice model with multiple modes in the passenger travel context, the literature is sparse in the freight context. The primary reasons being unavailability and/or the high cost associated with the acquisition of mode choice and level of service (LOS) measures--such as travel time and travel cost. The first contribution of the research effort is to develop travel time and cost measures for various modes reported in the CFS. The study considers five modes: hire truck, private truck, air, parcel service and other modes (rail, ship, pipeline, and other miscellaneous single and multiple modes). The LOS estimation is undertaken for a sample of CFS 2012 data that is partitioned into estimation sample and holdout sample. Subsequently, a mixed multinomial logit model is developed using the estimation sample. The exogenous variables considered in the model include LOS measures, freight characteristics, and transportation network and Origin-Destination variables. The model also accounts for unobserved factors that influence the mode choice process. The estimated mode choice model is validated using the holdout sample. Finally, a policy sensitivity analysis is conducted to illustrate the applicability of the proposed model.

Freight Transport Modelling is a unique new reference book that provides insight into the state-of-the-art of freight modelling. Focusing on models used to support public transport policy analysis, Freight Transport Modelling systematically introduces the latest freight transport modelling approaches and describes the main methods and techniques used to arrive at operational models. As freight transport has grown exponentially in recent decades, policymakers now need to include freight flows in quantitative evaluations of transport systems. Whereas early freight modelling practice was inspired by passenger transport models, by now it has developed its separate stream of methods and techniques inspired by disciplines such as economic geography and supply chain management. Besides summarizing the latest achievements in fundamental research, this book describes the state of practice and advises practitioners on how to cope with typical challenges such as limitations in data availability. - Uniquely focused book exploring the key issues and logistics of freight transport modelling - Highlights the latest approaches and describes the main methods and techniques used to arrive at operational models - Summarizes fundamental research into freight transport modeling, as well as current practices and advice for practitioners facing day-to-day challenges

"This report presents an evaluation of possible improvements in freight demand models and other analysis tools and provides a guidebook to assist model developers in implementing these improvements. The report is especially valuable for its findings of general satisfaction with methods available to support freight planning, but concerns with the data available to support that planning. As such, the report focuses on ways to use existing data to develop data inputs for the model, showing that existing and readily available data can be used to develop the inputs required by freight models. The report will enable decision makers at a range of geographical levels to improve the usability of freight demand models."--Pub. desc.

"This report provides a comprehensive analytical framework and related tools that private-sector freight transportation modes and public-sector transportation interests can use to estimate private and public benefits to evaluate potential freight infrastructure investments. Using interviews with transportation planners and an extensive review of prior research and a review of current methods used to assess freight benefits or prioritize improvement projects, the research developed a freight evaluation framework with three main functions: (1) to enhance public planning and decision-making processes regarding freight; (2) to supplement benefit/cost assessment with distributional impact measures; and (3) to advance public-private cooperation. The framework is capable of handling projects that span all of the different modes and able to assess benefits from a variety of project types, including those that improve freight operations, as well as generate more capacity through infrastructure expansion. The research, by developing a practical set of formats for information collection, will support public-private agency discussions by helping all parties understand the wide range of perspectives and interests in potential freight investments."--Pub. desc.

This paper presents a new approach to study the demand for intercity freight transportation. The model proposed in this paper utilizes the strength of discrete choice models (e.g., probit) in explaining the process of mode choice as one part of a complete model. The complete model is presented as a joint discrete/continuous choice model for the choices of mode and shipment size. The model is practical in that it requires the same amount and quality of data that would be required to develop a standard disaggregate mode choice model, and it can be estimated using simple two-stage estimation methods which utilizes standard probit maximum likelihood and ordinary least squares estimation techniques.
