This paper investigates transport services pricing problems faced by intermodal freight transport operators with fixed transport capacities in an intermodal freight transport network. We first present an optimal intermodal freight transport planning model to minimize the total transport cost. This model captures modality change phenomena, due time requirements, and the possibility to subcontrac...
Air transport industry has gradually increased its share of global passenger and freight traffic, and this trend has accelerated in the last 40 years. For the past decade, air-freight traffic growth has outpaced air passenger traffic growth by 1-2% each year. In the past, air-freight sector offered limited services, with heavy reliance on several intermediaries and a significant dependence on a...
International and interregional trade and transport are on the rise and hence, there is a clear need for reliable estimates of transport flows. However, the available databases and estimation methods are not yet satisfactory for analytical and predictive purposes. In this paper we explore the use of different statistical techniques in order to examine the spatial flow pattern of freight transpo...
Freight transport plays a fundamental role in the economy of every country. The performance of the European transport sector has been in line with the expanding economy. From 1995 to 2004 total European freight transport in the 25 Member States examined grew from 2,967,000 to 3,804,000 million tkm (+28 %). Considering only inland transport, it appears that the considerable growth was almost ent...
The geography of freight transportation evolves at various scales, but it is increasingly acknowledged that freight flows occurring at the local level are a result of global and regional economic processes. Internationally, distribution networks have expanded, namely through the division of production, manufacturing and consumption. This has been accompanied by a growth of the quantity of freig...
At present, high-speed rail is used only as a mode of passenger transport. Yet, the acceleration of logistics and freight transport flows could be compatible with high-speed rail capabilities. This article examines the experiences, literature and prospects of high-speed rail for freight. It uses three hypotheses to evaluate the development of freight high-speed rail services in Europe. The arti...
An overall objective of the REORIENT project is to develop a business case for a new rail service between the Nordic countries and countries in Centraland South Eastern Europe. We developed, conducted, and used information from a survey conducted by the REORIENT project among intermodal freight shippers in countries within the REORIENT Corridor to identify essential factors for attracting freig...
Freight transport in urban areas is of increasing interest and concern. Significant changes in patterns and intensity of freight movements are occurring as a result of technological and societal change and the growth in e-business, the environmental consequences of road based transport systems, and urban land use and transport systems management policies. One significant problem is the BrowneAl...
Freight transport has undesirable effects on the environment. The most prominent of these is greenhouse gas emissions. Intermodal freight transport, where freight is shipped from origin to destination by a sequence of at least two transportation modes, offers the possibility of shifting freight (either partially or in full) from one mode to another in the hope of reducing the greenhouse emissio...
Developing the country’s economic is a hot topic in Chinese society, and then the freight ability is a value that show the development of the local economic. The prediction of freight ability in country is benefit to the planning of country’s transport. This article choose suited input first, and then make up the GRNN model, at last ,predict the ability of the freight.
