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.

The purpose of this report is to demonstrate usage of Geographical Information Systems (GIS) for analyzing intermodal freight networks. A complete GIS network, focused on the state of Texas, is developed and used to examine impacts of price, time, location, and policy on shipper routing. This process begins with an exploration of existing GIS applications, and state of the practice within the intermodal freight industry. This information provides a framework for building a technically feasible and relevant application. Data acquisition and processing techniques for both geographic and attribute data are considered. Relevant processes for creation of a GIS network and data conflation are identified and demonstrated. These techniques are used to create a network modeling the complex interactions and transfer rules amongst modes. Finally, several case studies are developed using the completed network to exhibit the power of GIS applied to intermodal freight. The report concludes with a summary, and observations to assist others attempting to build upon these results.

Geographic Information Systems for Intermodal Transportation: Methods, Models, Applications examines the basic concepts and applications of Geographic Information Systems for Transportation. The book discusses the unique characteristics of each transportation mode-- highway, railway, waterway and airway—as well as the combined intermodal transportation network. The book shows how GIS generates vehicle routes and shorted paths, develops transportation demand models, analyzes spatial data, and how three-dimensional modelling is applied to the intermodal transportation. Includes real-world case studies from diverse situations Provides step-by-steps insights using data to deliver effective outputs for all stakeholders Presents models and practices for using GIS techniques to solve intermodal transportation problems Includes learnings tools such as chapter objectives, discussion questions and a glossary

Anticipating the need for Virginia to comply with the new freight planning requirements mandated by ISTEA and TEA-21, the Virginia Transportation Research Council in 1998 developed a Statewide Intermodal Freight Transportation Planning Methodology, which provided a standard framework for identifying problems and evaluating alternative improvements to Virginia's freight transportation infrastructure. The first step in the methodology was to inventory the system. This study completed that step. In this study, a freight advisory committee, consisting of public and private freight stakeholders, was formed. Next, county-level commodity flow data were commercially procured. Using these data, Virginia's "key" commodities were identified, and the flows of these commodities were assigned to county-level O-D tables. A geographic information system (GIS) database was developed that showed freight flows, county-level population and employment information, and Virginia's freight transportation network. With the use of various statistical analysis techniques, freight generation and attraction relationships were defined, and predictive equations were developed for each of Virginia's key commodities. Future freight flows were predicted, and various models with which to distribute these future flows were evaluated. The freight transportation GIS database, along with the analytical tools to predict and display future freight flows within Virginia, provides the Virginia Department of Transportation and its Freight Advisory Committee the means by which to identify problems, establish performance measures, and develop and evaluate alternatives to improve the flow of freight into, out of, and within Virginia

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.

" TRB's second Strategic Highway Research Program (SHRP 2) Report S2-C20-RR-1: Freight Demand Modeling and Data Improvement documents the state of the practice for freight demand modeling. The report also explores the fundamental changes in freight modeling, and data and data collection that could help public and private sector decision-makers make better and more informed decisions. SHRP 2 Capacity Project C20, which produced Report S2-C20-RR-1, also produced the following items: A Freight Demand Modeling and Data Improvement Strategic Plan, which outlines seven strategic objectives that are designed to serve as the basis for future innovation in freight travel demand forecasting and data, and to guide both near- and long-term implementation: A speaker's kit, which is intended to be a "starter" set of materials for use in presenting the freight modeling and data improvement strategic plan to a group of interested professionals; and; A 2010 Innovations in Freight Demand Modeling and Data Symposium " -- publisher's 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.
