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

This book was released on 1998 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The researchers developed a methodology for statewide freight transportation planning that focuses on identifying and prioritizing infrastructure needs to improve the intermodal freight transportation system. It is designed to provide the framework for state departments of transportation and metropolitan planning organizations to meet the freight transportation planning requirements as mandated first by the Intermodal Surface Transportation Efficiency Act of 1991 and then by The Transportation Equity Act for the 21st Century. The researchers accomplished this by interpreting the results of a literature search on the legislation, participant roles, and analytical methodologies to formulate the steps of the method and demonstrating how each step is performed. The process is based on the interaction between inputs from stakeholders and a technical analysis that provide decision support information. A case study demonstrates how the technical tasks for the system inventory and data forecasting are accomplished. The study shows that a standard but flexible freight planning methodology can help remove impediments to efficient goods transportation. Future developments such as geographic information system data, improved freight flow data, and established system inventories are shown to facilitate the recommended process.

This book was released on 2008 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the challenges attributable to increasing freight traffic and roadway congestion it is necessary to investigate opportunities for better management of goods movements. Rail-truck intermodal freight transportation can be considered as one such solution for reducing long-haul truck traffic on highways. For the rail-truck intermodal freight transportation to act as an effective transportation alternative, it is necessary to evaluate its impacts on the transportation system. A framework for evaluation of rail-truck intermodal terminal projects with qualitative and quantitative measures has been established using public goals and private stakeholder perspective. With the use of a case study, some of these measures have been evaluated. Recommendations have also made on data collection procedures for making a full scale evaluation. The case study selected for the Project is the proposed freight intermodal terminal at Petersburg, Virginia, conceived by the Norfolk Southern Corporation. This analysis formed a bridge between a region and a corridor based analysis. The key findings of the study are as follows: (a) Evaluation of an intermodal terminal project requires a systematic multi-regional modeling approach; (b) The impacts of an intermodal terminal are region and trade corridor specific; and (c) In cases where estimated intermodal rail drayage forms a small share of the overall truck traffic, the introduction of an intermodal terminal does not have substantial impacts on accessibility, mobility or safety. The study successfully developed models for estimation of impacts, including a two-stage accessibility model for drayage, a truck-rail mode choice model, truck involved crash models, and secondary local freight traffic impact model, mainly using data from the Commonwealth of Virginia.

Available in PDF, EPUB and Kindle. Book excerpt: With the completion of the Interstate highway system the transportation planning focus has changed. Fiscal constraints preclude system expansion at the pace needed to support continued robust economic growth. Therefore, attention in the public sector has shifted to getting more productivity out of the existing modal infrastructure through improvements in system operation and management. This shift from capital construction to asset management is also motivated by increased emphasis at all governmental levels on minimizing the adverse environmental and societal effects of transportation activities. In concert with these public sector forces has been the emergence of a vibrant and highly competitive global marketplace. International trade and transportation agreements have opened the door to continued explosive growth in global commerce. The successful global enterprises are characterized by efficient logistics involving just-in-time inventory systems and a strong emphasis on customer service. The transport demands of international corporations are forcing transportation service providers to be more efficient and responsive. The combined effect of these public and private sector forces is a sea change in the way the transportation system is planned, designed, and deployed. A major element of this transportation paradigm shift involves a view of the modal systems as components of a single, integrated transportation system where each mode plays a role based on its inherent strengths. This view motivates a search for technical and institutional improvements to enhance the "seamless" flow of goods and people between the modes. In this emerging intermodal era, there will be increasing opportunities for the public and private sectors to make worthwhile investments in intermodal facilities and technology. It follows, therefore, that planning attention will be focused on improving intermodal interconnectivity. Also, the public sector will be faced with important transport policy decisions, such as carrier regulation/deregulation, truck size and weight restriction changes, and continued consolidation of the major rail carriers. Planners and decision makers will need reliable data and transportation systems analysis tools to evaluate intermodal project and policy alternatives. Within this overall global transportation system context, this report focuses on the freight transportation planning for a major corridor. The Interstate 81 corridor is a case in point. I-81 runs from upstate New York to Tennessee through Pennsylvania, the Maryland and West Virginia panhandles and Virginia and is characterized by a high level of truck travel over much of the corridor. In spite of this corridor focus, several of the conclusions drawn in this report are relevant for freight transportation planning in general

This book was released on 1996 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis describes the process by which state departments of transportation and Metropolitan Planning Organizations (MPOs) integrate freight planning into the surface transportation planning process. It will be of interest to state and MPO planners, port planners; traffic engineers; and to the trucking, rail, and shipping interests in both the public and private sectors. This report of the Transportation Research Board discusses the requirements for freight planning resulting from the Intermodal Surface Transportation Efficiency Act (ISTEA) with particular emphasis on the development of an intermodal management system (IMS). In addition, that act narrowed the application of the congestion management system (CMS), which is also discussed in the synthesis. Since enactment of that legislation, another act, the National Highway System Designation Act of 1995 was passed and makes the IMS optional rather than mandatory. This has not changed the philosophy or the intent of these planning applications, but it has changed the implementation aspects. Many agencies, however, are continuing with the IMS and CMS planning process. This report describes the methods used by selected agencies for forecasting freight flows, data collection practices, and the techniques for integrating freight planning into the established surface transportation planning processes at the state and regional levels.

Book excerpt: This report presents the recommendations and findings from a study of the feasibility of establishing a program for collecting and reporting commodity flow information for the Montana Department of Transportation (MDT). Historically, the MDT has had a strong interest in ensuring that there is a good data base from which to determine Montana freight transportation needs. This has resulted in the collection and reporting of freight related information as part of statewide planning, rail planning, special studies, and in an ongoing traffic monitoring program by MDT. MDT managers and a sample of freight transportation providers were interviewed to identify MDT commodity flow data requirements. The focus of the study is on commodity flow information and not freight or goods movement information. The interview results provide perspective on data requirements at each level of the organization. The interview findings, and the evaluation of MDT ongoing goods movement related planning, indicate that MDT commodity flow data requirements are largely met, and that the principal unmet requirements are for a better baseline of information on current and future goods movement. It is not recommended that MDT proceed with conducting a commodity flow data collection and study, as the information collected would have only a narrow use in the department.

This book was released on 2003 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that better freight forecasting models and data are needed, but the literature does not clearly indicate which components of the modeling methodology are most in need of improvement, which is a critical need in an era of limited research budgets. This effort sought to identify those components using a logistics-driven approach as a starting point. The research began by examining other states' responses to freight planning legislation. A survey was sent to 47 states to determine the types of freight planning and freight modeling that occur and to understand the current data available and data needs. Research was conducted to gather information on how the supply chain functions and how logistics decisions regarding supply chain management are made. Sample supply chains were created for a variety of commodities, and mode choice was related to the behavioral aspects of the supply chain's logistics system. Once the mode was determined, the route assignment could be determined based on the accessible freight infrastructure. It was found that not all elements of the freight modeling methodology are equally weak: indeed, trip attraction components for the production of raw materials and the dissemination of these materials from the manufacturing plant, whether to the consumer (in a traditional push system) or to a just-in-time distribution center (in the newer pull system) are adequately developed in practice. However, it is critical that future research address the following needs, listed in order of descending priority: (1) the mode choice component for delineating travel by air, truck, rail, water, or a combination thereof; (2) trip attraction equations for intermodal facilities that are used when manufacturing plants outsource key components rather than creating all components in-house, and (3) trip attraction equations for representing the flow of goods from distribution centers to the consumer.

This book was released on 2017 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword: "NCFRP Research Report 37 provides policy makers with improved establishment-level models that estimate the freight trip generation (FTG), the number of vehicle trips produced and attracted at a given establishment; the freight production (FP), the amount of cargo produced by the establishment; and the service trip attraction (STA), the number of vehicle trips that arrive at the establishment to perform a service activity. These models, estimated with the best data available, provide tools to assess the various facets of the overall freight and service activity (FSA) that takes place in urban and metropolitan areas. The models will allow transportation practicitioners to conduct sound curb-management, proerply size loading and unloading areas, support traffic impact analyses, and improve transportation planning and management efforts."--Page v.
