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...

This study proposes an alternative approach to estimate excess travel using activity diaries, extending it to non-work travel and capturing interhousehold variation. Central to this approach is a residential relocation exercise that helps to decompose the amount of travel by a household into two...

This chapter develops a model to simulate contemporary competition between network and point-to-point (PP) carriers in air transportation markets. In particular, we focus on the transition from the strategies of network carriers to the behavior of PP carriers. The concept of multilevel...

With this article we use an alternative form of the discrete choice model to analyze the distribution of maritime shipments among US ports. We model the distribution as a function of the characteristics that describe each shipment and each port. We assume that vessel schedules are fixed in the...

This study explores the relation between airline market structure and schedule differentiation. Using a location theory framework applied to product differentiation over the time scale, the analysis relates the level of competition, and the presence of low-cost carriers in non-stop US markets to...

In this paper are presented the results of a multinomial logit model used to explain the selection of a port for each shipment exported from the US in December 1999. The model is estimated for combined shipments, and one model is estimated for each of four commodity types (bulk, foods, fabrics,...
