Nowadays, the impacts of transportation systems on the environment and the society are undeniable. Considering the great environmental awakenings at the planetary level and the discounted growth of the carriage of goods per transportation mode within the European Union, the distribution and haulage companies must start to take measures to limit their impacts. We aim to build a multi-criteria de...
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...
We present a two-stage approach for the "helicopters and vehicles" intermodal transportation of medical supplies in large-scale disaster responses. In the first stage, a fuzzy-based method and its heuristic algorithm are developed to select the locations of temporary distribution centers (TDCs) and assign medial aid points (MAPs) to each TDC. In the second stage, an integer-programming model is...
This paper presents a holistic analysis for the network design problem of the intermodal liner shipping system. Existing methods for liner shipping network design mainly deal with port-to-port demand. However, most of the demand has inland origins and/or destinations. Thus, it is necessary to cope with inland origin-destination (OD) pairs involving a change in transport mode from inland transpo...
As state transportation planners seek to build or support sustainable transportation systems in an era of economic challenges, they find few publicly available rail analysis models for stakeholders to examine the environmental impacts, socio-economic effects and costs associated in investing in rail infrastructure. This paper, taken from a University Transportation Center Program (UTCP Region 6...
The current literature in the rail–truck intermodal transportation of hazardous materials (hazmat) domain ignores congestion at intermodal yards. We attempt to close that gap by proposing a bi-objective optimization framework for managing hazmat freight that not only considers congestion at intermodal yards, but also determines the appropriate equipment capacity. The proposed framework, i.e., a...
Very few research efforts have been spent on the coordination of plans and operations of independent carriers in an intermodal transportation chain. The impact of this lack of collaboration and coordination is shown in an accordant scenario and first ideas are presented to overcome this situation following the principles of decentralized planning.
China’s cross-border e-commerce companies are facing the problem of high logistics cost caused by excessive reliance on road transportation in domestic link. In long-term development, crossborder United States have adopted intermodal mode, which can reduced costs. order to study impact intermodal-transportation mode scale companies, this paper selects relevant data Hub Group, first marketing co...
