This paper applies a geospatial network optimization model to explore environmental, economic, and time-of-delivery tradeoffs associated with the application of marine vessels as substitutes for heavy-duty trucks operating in the Great Lakes region. The geospatial model integrates U.S. and Canadian highway, rail, and waterway networks to create an intermodal network and characterizes this netwo...

The waste intermodal station of Clyde, in the city of Sydney, Australia, is in the heart of a complex network of terminals connected by road and rail to transport urban waste from its first collection to its final disposal. The amount of waste the network is projected to handle in 2015 will increase from about 340,000 tonnes/year in 2006 up to about 1.5 million tonnes/year, following population...

We consider a container routing problem with stochastic time variables in a sea-rail intermodal transportation system. The problem is formulated as a binary integer chance-constrained programming model including stochastic travel times and stochastic transfer time, with the objective of minimising the expected total cost. Two chance constraints are proposed to ensure that the container service ...

A significant proportion of worker fatalities within Australia result from truck-related incidents. Truck drivers face a number of health and safety concerns. Safety culture, viewed here as the beliefs, attitudes and values shared by an organisation's workers, which interact with their surrounding context to influence behaviour, may provide a valuable lens for exploring safety-related behaviour...

The projected growth in container traffic at ports of New York and New Jersey, along with the expected regional growth of commuter traffic, will cause a significant increase in traffic congestion. This will result in deteriorating performance of the regional transportation system, including highway system providing access to the port. Because of limited ability to expand highway and rail infras...

The multimodal trip planning system (MTPS) described in this paper can efficiently identify reasonable journeys. Our methodologies could be implemented in future transit trip information systems. An effective MTPS would be of value to transit agencies or administrators due to the large number of different yet related characteristics of the transit network. In Taiwan, no successful MTPS exists o...

We investigate a spectrum of decision-making approaches, from centralized to decentralized, within the context of scheduling direct and indirect (via a hub) trains and assigning containers to trains for the rail (linehaul) portion of the intermodal trip. The goal is to minimize operating costs, including a fixed charge for each train, variable transportation and handling costs for each containe...

At rail-road transshipment yards, gantry cranes move containers from freight trains to trucks and vice versa. They constitute important entities in today's intermodal transportation systems. Real-world yards are often partitioned into several disjunct crane areas, so that crane interferences during container transshipment are avoided. In practice, the lengths of such crane areas are typically d...

This study defines a methodology to compute unitary costs for freight transportation modes. The main objective was to gather relevant costs data to support the formulation and evaluation of railway, road, pipelines and port projects. This article will concentrate on the following steps: Compilation and analysis of relevant modal cost studies, Methodological adjustments to make cost figures comp...

Efficient transport solutions are based on multimodal systems, with the dominant role of rail and road in land versions systems connecting directing part intermodal terminals, transhipment terminals or warehouse centres. The implementation processes is always associated risk lack timeliness (quality) threats to people, equipment cargo (safety) resulting from human, technical, organizational glo...
