Previous research on the joint economic lot size (JELS) problem was focused on the decisions of lot sizes and batches delivered among players in the supply chain, assuming that transportation cost was independent of shipment amounts. Nevertheless, the transportation cost accounts for a major part of supply chain cost, especially when transportation companies offer freight rate discount schedule...

Travel, like many other aspects of daily life is being transformed by the information technology revolution. Accessibility can no longer be measured only in terms of travel time, distance or generalized travel cost. Information technology gives people virtual accessibility to a rapidly growing range of activities. E-commerce has become a catalyst for structural changes in the freight transporta...

The current weaknesses of the conventional intermodal freight transportation system have led to the development of the synchromodal freight transportation concept introduced and piloted in the Netherlands. The innovative concept has the advantage of adding flexibility, cost reduction, and sustainability among other things, into the freight transportation system. The synchromodal system has not ...

Automated public urban freight transportation networks have the potential to greatly increase the energy efficiency of material transport by more closely matching the mass of the goods being transported with the mass of the transportation apparatus and reduce the cost to society by removing the requirement for human supervision for each package. In this paper, we present an overview of the cons...

This paper describes freight movements in the Upper Midwest. The study was undertaken as a part of a multi-state freight study conducted by a team led by the Midwestern Region University Transportation Center at the University of Wisconsin. Using various secondary data sets, the analyses provide a picture of how goods move to, from and within the region to better understand the freight transpor...

Logistics are an important function of modern transport systems. Contemporary technological and spatial developments have improved the cost, efficiency and reliability of freight and passenger transport systems. At the same time, the negative environmental impacts of transportation have gained wide recognition and are at the core of issues of sustainability, especially in urban areas. Since the...

Travel, like many other aspects of daily life is being transformed by the information technology revolution. Accessibility can no longer be measured only in terms of travel time, distance or generalized travel cost. Telecommunications provides people with virtual accessibility to a rapidly growing range of activities and real-time information about travel conditions. E-commerce has become a cat...

Freight movements throughout the Mississippi Valley region are complicated by the presence of recurring congestion along the highway, rail, and port freight networks. This congestion has several deleterious effects on freight carriers, commuters, governments, and markets. State departments of transportation (DOTs) in the Mississippi Valley Freight Coalition are looking to identify the points of...

Research on freight transportation has seen a tremendous increase in the last decades, yet it lags behind that on passenger travel, particularly at a macro-level suitable for nation-wide policy analysis. A key challenge in freight demand modeling is the availability of data on key drivers of demand such as cost, time, and trip length which usually is proprietary and expensive. Moreover freight ...

The 21st century will see a renewed focus on intermodal freight transportation driven by the changing requirements of global supply chains. Each of the transportation modes (air, inland water, ocean, pipeline, rail, and road) has gone through technological evolution and has functioned separately under a modally based regulatory structure for most of the 20th century. With the development of con...
