The paper describes a prototype Dynamic Freight Traffic Simulation model called DyFTS, constructed for studying the effects of highly developed information technologies and logistic strategies on freight transportation. DyFTS is designed as a highly adaptable system that can be easily embedded into a more comprehensive transportation simulation model. Various decision-making processes are formu...

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...

Freight transport modelling at interregional scale is relevant for planning issues. However, freight modelling processes are complex because it is not easy to define the relevant variables in the analysis, and to obtain the required information on freight movements through the network. These facts raise the need to adapt the modelling framework to each context. This paper proposes a strategic n...

Pricing schemes have been proposed to address the negative externalities of freight transportation. Literature related to the following pricing strategies are reviewed: pricing programs aimed at changing shipper’s mode choice, and schemes aimed at shifting freight deliveries to off-peak hours. Evidence from empirical and theoretical studies suggests that pricing strategies may have limited effe...

Freight transportation has increased very rapidly in the Republic of Korea owing to economic growth and expanding international trade. However, the freight transport sector in the Republic of Korea has been regarded as inefficient and the inefficiencies can be attributed to many factors, including an outdated regulatory framework, business practices and a lack of proper infrastructure. Since fr...

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...

Nonlinear vibration of parabolic springs employed in suspension system of a freight car has been studied in this paper. First, dynamical behavior of the springs is investigated by using finite element method and the obtained results are then used in vibration analysis of a railway freight car. For this purpose, dynamics of a parabolic spring subjected to a cyclic excitation has been studied ...
