We study interaction between the trips of two types of drivers on a two-lane road who differ by their desired speeds. The difference in desired speeds causes congestion, because slow drivers force fast drivers to reduce their speed. An interesting aspect of this type of congestion is that...

This paper deals with the issue of regulatory reform in the airline industry, in connection with environmental externalities. Deregulation has led to shorter routes, higher frequencies, probably larger aircraft sizes and more intense peak traffic at airports. In addition, deregulation has led to...

Substantial differences exist among fuel taxes in various countries. These differences represent a form of fiscal competition that has undesirable side effects because it leads to cross-border fuelling and hence to extra kilometres driven. One possible way of solving the problem of low fuel...

Frequency of services and vehicle size are important policy instruments of railway companies. Extending Mohring's basic 'square root model' for frequencies, we arrive at more general formulations for frequency, vehicle size and price under alternative regimes of welfare and profit optimisation....

In travel surveys most respondents apply rounding of departure and arrival times to multiples of 5, 15 and 30 minutes: in the annual Dutch travel survey about 85-95 percent of all reported times are 'round' ones. We estimate rounding models for departure and arrival times. The model allows one...

The outer islands in Indonesia are often seen as the main source of migrants to the island of Java, while

This paper aims to address the linkage between logistics (in particular, the management of marketing channel flows) and transport markets, while also the interaction between these two markets and inter-modal container terminals is analysed. The marketing channel theory is used to describe all...

In urban areas underground logistical systems - designed as delivery service to provide shops, industrial sites and office locations - may help to relieve the pressure of the road network in particular in the old inner cities which have to deal with increasing traffic congestion. When shops are...

In this study differences in airfares between citypairs will be analysed. We distinguish three types of city pairs: pairs within western Europe, pairs within eastern Europe and pairs between western and eastern European cities. In this study the differences in airfares of the national carriers...
