Freight transportation has long been recognized as an important foundation of economic strength. Previous studies use traditional methods to examine a set of scenarios. However, due to the complexity of transportation projects which can have substitution effects in a network the number of resulting scenarios may be more than can be examined on a case by case basis. In this paper, a sequential s...

Understanding policy impacts on freight is essential for planners who have overlooked this transport group in the past and must evaluate new congestion alleviation policies with respect to regional economic and social goals. Since urban areas are limited in infrastructure expansion and travel demand continues to rise, congestion pricing is a potentially compelling policy alternative. This thesi...

There is a significant interaction between sizing a fleet of rail cars and its utilization. This paper presents a new multi-period mathematical model and a solution procedure to optimize the rail-car fleet size and freight car allocation, wherein car demands, and travel times, are assumed to be deterministic, and unmet demands are backordered. This problem is considered NP-complete. In other wo...

Abstract International cargo containerization system continues progressive development supporting increase of multimodal transport traffic. Containerized commodity transportation schemes are highly efficient for majority transcontinental and long-distance deliveries optimizing costs, time quality operations basing on exact forecasting container turnover. Following these headline routes, researc...

Three piece bogies are widely in use by the freight railway services throughout the world. In comparison with the other freight bogies they cost less and are easier to maintain. However, they do not exhibit favorable curving behavior. Amongst the methods to improve the bogie performance is the proposal to introduce lateral clearance in the bogies’ axleboxs. In the case of the three piece bogies...

Recent empirical studies in maritime economics define market contractions and expansions (market dynamic movements) as shipping agent controlled, distinguishing between cargo-owner and ship-owner markets. It is argued that freight dynamics are triggered by the activities of shipping agents, in the sense that both a higher earning market-state with high volatility and a lower earning market-stat...

This paper presents the issues surrounding the integration and visualization of freight data using internet-based mapping applications. In relation to Internet-based mapping technology in freight data collection and planning we: (a) address implementation issues associated with data integration, (b) present a system architecture to leverage existing publicly available interfaces and web applica...
