Background: Road transport companies utilize transport capacities as fixed compositions of tractors and semi-trailers, while the possibility of exchanging semi-trailers is considered ad hoc, after some unforeseen circumstances emerge on the route. Such an approach is a limiting factor in...

Die Dissertation beschäftigt sich mit der Entwicklung der taktischen Optimierungsmodelle für globale und regionale Containersteuerung. Die Modelle beinhalten gemeinsame, spezifische Durchschnittsparameter, die den Zusammenhang zwischen den Steuerungsebenen ermöglichen. Die Probleme werden als...

Transportation engineers are taught that as demand for travel goes up, this decreases not only speed but also the capacity of the road system, a phenomenon known as hypercongestion. We revisit this idea. There is no question that road systems experience periods in which capacity falls. However,...
