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.… (More)
An analytical model is developed to assign regional freight across a multimodal highway and railway network using geographic information systems. As part of the regional planning process, the model is an iterative procedure that assigns multimodal freight traffic to the network to achieve overall network optimum. The procedure integrates optimization… (More)
The movement of freight is an important but often overlooked aspect of the transportation system. While much research and planning has centered on passenger transport, freight demand and modeling have received relatively little attention due to lack of appropriate data from which accurate vehicle flows could be predicted. This report proposes a methodology… (More)
