Assembling and Processing Freight Shipment Data


Book Description

This research focuses on establishing a systematic non-survey-based method for developing an origin-destination (OD) matrix of freight flows based on secondary data sources. The estimated freight flows and concurrent passenger volumes are loaded onto the regional highway network in the greater Los Angeles area of Southern California. Economic analyses, modeling, and GIS technologies are integrated into building a GIS-based OD matrix for freight flow. In order to load the freight flows onto the regional highway network, a three-step feedback transportation model is developed. It includes trip generation, trip distribution, and traffic assignment. A doubly-constrained gravity model is used to co-distribute and calibrate personal trips and freight trips in the trip distribution step. A version of User-Optimal-Strict On Network Assignment (UO-S-NA) is used to assign all of the vehicle trips to the regional highway network.




Modeling Intermodal Freight Flows Using GIS


Book Description

The purpose of this research is to demonstrate the use of Geographical Information Systems (GIS) for analyzing Intermodal Freight Networks. A complete GIS network comprising of the seven states of 1) Illinois, 2) Indiana, 3) Iowa, 4) Michigan, 5) Minnesota, 6) Ohio and 7) Wisconsin of the upper Midwest region of United States is created using Oak Ridge National Laboratory's (ORNL) Intermodal Network Database. The GIS application for Intermodal freight flow analysis developed in this research is capable of displaying Intermodal freight flows on the transportation network, based on, "Finding Shortest Path" concept of minimizing total transportation costs. Specifically, a network capable of analyzing containerized freight movements has been developed. The research begins with an exploration of existing GIS applications and the state of the practice in the intermodal freight industry. A simple mathematical model is formulated taking into account the multiple modes and complex routing rules involved in the intermodal freight transportation. This research concludes demonstrating the ability of GIS to analyze intermodal freight flows over a transportation network.




Development of Analytic Intermodal Freight Networks for Use Within a GIS.


Book Description

The paper discusses the practical issues involved in constructing intermodal freight networks that can be used within GIS platforms to support inter-regional freight routing and subsequent (for example, commodity flow) analysis. The procedures described can be used to create freight-routable and traffic flowable interstate and intermodal networks using some combination of highway, rail, water and air freight transportation. Keys to realistic freight routing are the identification of intermodal transfer locations and associated terminal functions, a proper handling of carrier-owned and operated sub-networks within each of the primary modes of transport, and the ability to model the types of carrier services being offered.




Modelling Freight Transport


Book Description

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







Freight Transport Modeling in Emerging Countries


Book Description

Freight Transport Modeling in Emerging Countries examines freight transport models developed in emerging countries including Turkey, South Africa, India, Chile, and more. It provides a toolbox of successful freight transport model applications, alternative data collection methods, and evaluation techniques for the development of future policies. The book offers solutions for issues related to the urban, national, and international transportation of goods and examines new advances in freight transport models and data collection techniques and their applications in emerging countries. Emerging countries have unique transport-related policies, regulatory structures, logistics systems, and long-term uncertainties that hinder their economic development. This book tackles these issues by examining decision-making models for locating logistics sites such as ports and distribution centers, modeling urban freight movements in megacities and port cities, using existing datasets to get information when data is not available, implementing policies related to the national and international movements of goods, and more. Includes a wide variety of opinions and approaches from subject matter experts around the world Utilizes a case-based approach Includes a range of learning tools that feature chapter openers, end of chapter questions, a glossary, and more Examines new advances in freight transport models and data collection techniques




Recent Developments in Transport Modelling


Book Description

Discusses Professor Marvin L Manheim's contributions to transportation. This book presents his vision for the role of ICTs in transport. It covers topics including predictions of production to consumption freight flows through the use of multi regional input-output models, and choice analysis using freight market research surveys.




Sustainable Intermodal Freight Transportation


Book Description

"To study the energy and environmental impacts of emissions associated with freight transportation, the Geospatial Intermodal Freight Transport (GIFT) model was created as a joint research collaborative between the Rochester Institute of Technology (RIT) and the University of Delaware (UD). The GIFT model is a Geographic Information Systems (GIS) based model that links the U.S. and Canadian water, rail, and road transportation networks through intermodal transfer facilities to create an intermodal network. The purpose of my thesis is to apply the GIFT model to examine potential public policies related to intermodal freight transportation in the Great Lakes region of the United States. My thesis will consist of two papers. The first paper will examine the environmental, economic, and time-of-delivery tradeoffs associated with freight transportation in the Great Lakes region and examine opportunities for marine vessels to replace a portion of heavy-duty trucks for containerized freight transport. The second paper will explore the potential benefits of using the Great Lakes as a corridor for short-sea shipping as part of a longer intermodal route. The intent of my thesis is to shed light on the current issues associated with freight transport in the Great Lakes region and present public policy alternatives to address said issues. Ideally, this thesis will better inform policymakers on the impacts and tradeoffs associated with freight transportation."--Abstract.
