Travelers tend to place a high value on qualitative factors such as convenience, comfort, security and prestige. However, conventional transport planning practices tend to focus on quantitative impacts and undervalue qualitative impacts. This paper describes ways to evaluate qualitative impacts. Improved travel convenience and comfort tend to reduce unit travel time costs and so are equivalent ...

The optimization of fare systems in public transit allows to pursue objectives such as the maximization of demand, revenue, profit, or social welfare. We propose a non-linear optimization approach to fare planning that is based on a detailed discrete choice model of user behavior. The approach allows to analyze different fare structures, optimization objectives, and operational scenarios involv...

We consider the ship planning problem at maritime container terminals where containers are loaded onto and discharged from ships using quay cranes. The container transport between the ships and the yard positions in the terminal is carried out by a fleet of straddle carriers. Based on a stowage plan provided by the shipping company, the dispatcher assigns containers to specified bay positions. ...

An important problem in transportation is how to ensure efficient operational route planning when several vehicles share a common road infrastructure with limited capacity. Examples of such a problem are route planning for automated guided vehicles in a terminal and route planning for aircraft taxiing at airports. Maintaining efficiency in such transport planning scenarios can be difficult for ...

Fuzzy logic is shown to be a very promising mathematical approach for modelling traffic and transportation processes characterized by subjectivity, ambiguity, uncertainty and imprecision. The basic premises of fuzzy logic systems are presented as well as a detailed analysis of fuzzy logic systems developed to solve various traffic and transportation planning problems. Emphasis is put on the imp...

In optical transport networks, recent development of new technologies has led to highly accelerated (`disruptive’) increases in the capacity associated with a given investment cost. As a result, there have been dramatic decreases in the cost per unit of transport. We describe a nonlinear mixed-integer planning model that assumes both the continuous emergence of new systems and a constant-elasti...

In this paper, we study a logistics problem arising in military transport planning. A military organization operates a large fleet of vehicles in a depot to serve the requests of various operational units. Each request has a fixed start and end time, and is served by a prescribed number of vehicles. We address the following two problems: (1) how many vehicles are at least needed to meet a given...

This article reports about investigations on a transport scheduling scenario. The generated schedule requires a repeated revision in order to incorporate additionally released requests. Neither the release time nor the location of the associated customer site can be forecasted. Special attention is paid to keep the generated schedules stable, which means that once made scheduling decisions shou...
