Incidents are notorious for their delays to road users. Secondary incidents – i.e., incidents that occur within a certain temporal and spatial distance from the first/primary incident – can further complicate clearance and add to delays. While there are numerous studies on the empirical...

The problem of optimal container vessels deployment is one of great significance for the liner shipping industry. Although the pioneering work on this problem dates back to the early 1990s, only until recently have researchers started to acknowledge and account for the significant amount of...

Sensors are becoming increasingly critical elements in contemporary transportation systems, gathering essential (real-time) traffic information for the planning, management and control of these complex systems. In a recent paper, Hu, Peeta and Chu introduced the interesting problem of...

In this paper we present a novel methodology to assess travel time reliability in a transportation network, when the source of uncertainty is given by random road capacities. Specifically, we present a method based on the theory of Fourier transforms to numerically approximate the probability...

An assumption that pervades the current transportation system reliability assessment literature is that probability distributions of the sources of uncertainty are known explicitly. However, this distribution may be unavailable (inaccurate) in reality as we may have no (insufficient) data to...

This paper presents a rule for allocating joint vehicle costs between fronthaul and backhaul truck trips on a given route. The rule is derived by extending the De Vany and Saving model of a competitive trucking industry operating in uncertain markets. The rule is based upon the existence of...

This paper investigates the long-run cost structure of a specific firm of the U.S. urban multiservice transit industry, thereby permitting inferences to be made to the long-run cost structure of similar firms in the industry. The empirical results indicate that the firm exhibits economies of...

This paper presents an economic theory of the public transit firm that considers the public transit firm's operating objectives related to size maximization and cost minimization as well as its operating options and passenger quality-of-service characteristics. The theory indicates that the...

This paper considers costing criteria to evaluate various single capacity and alternative capacity rules for allocating shared costs among transportation movements (i.e. determining fully allocated costs). The costing evaluation criteria are: (1) core allocations, (2) encourages internally...
