Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Development of a GIS Model for Intermodal Freight written by Glenn Collin Standifer and published by . This book was released on 2000 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Application of a Statewide Intermodal Freight Planning Methodology written by James J. Brogan and published by . This book was released on 2001 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

In addition, it enhances readers’ spatial understanding of, and geographical reasoning in connection with, societal issues. The book will appeal to scientists, teachers and students of geography, the earth sciences and related areas, as well as decision-makers interested in the application and capabilities of geospatial technologies and new, spatial methods for addressing important issues.
Download or read book Modeling Intermodal Freight Flows Using GIS written by Praveen Kumar Chanda and published by . This book was released on 2004 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Forecasting Statewide Freight Toolkit written by Cambridge Systematics and published by Transportation Research Board. This book was released on 2008 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal planning legislation and regulations now mandate that state departments of transportation and metropolitan planning organizations consider the needs of freight when planning and programming transportation investments. While there are standard techniques used to forecast the movement of people, less attention has been paid to forecasting freight movements, and there are consequently fewer standardized techniques that state and local agencies can adapt to their local situation. This Toolkit is designed to provide transportation planners with the information they need to prepare forecasts of freight transportation by highlighting techniques successfully developed by state agencies across the country.
Download or read book GIS based Freight Density and Capacity Modeling written by Alex Wong and published by . This book was released on 1997 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the development of geographical information systems (GIS) based tools for use in the trucking industry. The primary goals are to link the GIS with appropriate database information to support both operational and strategic decision making in both truckload (TL) and less-than-truckload (LTL) operations. The GIS-based tools support three primary deliverables. In the LTL industry, we have developed tools to support the determination of near-optimal locations for breakbulk terminals. In the TL industry, we have developed tools to aid in the development of regularly scheduled capacity in the form of driving "lanes" in an effort to regularize the driving job and to improve service in that industry. For both industries, we have made use of regression analysis to determine the level to which we can make use of demographic information to predict freight density. For all three deliverables, the GIS software system supports the key prerequisite of freight density analysis. Also, the GIS platform provides excellent graphics capabilities for visualizing the various analyses and solutions. The result is an integrated solution platform that enables the trucking industry to better utilize delivery capacity and to proactively seek solutions to problems of strategic importance
Download or read book Development of Analytic Intermodal Freight Networks for Use Within a GIS written by and published by . This book was released on 1997 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
