This study proposes a framework to identify and measure the extent of product differentiation among services provided by transportation firms, and applies it to the US domestic airline markets. By formulating and estimating an Almost Ideal Demand System and a set of price response equations for...

This paper investigates the role of preference and scale heterogeneity in the mode choice process of shippers in the Atlantic Canada-US eastern seaboard market. The generalised mixed logit model is estimated to account for heterogeneity in preferences for frequency of departure of freight...

This paper presents the results of nine independent studies that link a seaport container terminal's long-run average quay crane rate to various strategic and tactical decisions made by the terminal operating company. New numerical results on yard capacity, fleet composition, truck...

In this supplement, a number of integrated models under the integer multiplier coordination mechanism is generalized by allowing complete backorders penalized by not only linear but also fixed costs for some/all retailers. The optimal solution to such a three-stage generalized model is...

This paper develops approaches for incorporating informational and operational dynamics within models for intermodal drayage operations with flexible tasks. Tasks with flexible origins or destinations create an important complexity. We develop models to minimize the cost of drayage moves when...

This paper simulates a dynamic traffic network by embedding an extra nonlinear delay function to represent traffic lights (or a similar regular delay) in each arc (or link), and it was shown that a late start driver may catch up with one who started earlier, subject only to the condition that...

In this study, we develop a solution method for solving air express cargo loading problems under stochastic demands. The method is designed by combining the scenario decomposition and genetic algorithm (GA) techniques. Numerical tests are performed to evaluate the performance of the solution...

In this paper, we estimate alternative specifications of the Spanish airports' cost function with the objective to provide a comparative analysis on several technological features such as output-specific marginal costs, economies of scale, and the Allen elasticities of substitution. We found...

In this paper we develop a model which approximates the upstream supply chains for embodied transportation in products. The sector with the largest embodied freight transportation in consumption is petroleum products followed by government services, construction, and food products. Overall,...
