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

The ‘backhaul problem’ is characterized by an imbalance in transport flows between locations. This problem is usually studied in a perfectly competitive framework, which essentially predicts that when the imbalance is sufficiently large, the freight price of transport from low demand regions...

The Spatial Interaction Model proposed by Alonso as "Theory of Movements" offers a new specification of spatial origin- destination flow models. Equations for flows between regions, total outflow from and total inflow to a region are linked by balancing factors. The paper presents a consistent...

Transport is characterised by market failures that are of particular importance in urban settings. This paper reviews market failures and policy failures in The Netherlands for various transport markets, including road transport, public transport and biking. Special attention is paid to parking...

This paper investigates the welfare effect of adverse weather through changes in the speed of individuals’ car commuting trips in the entire Netherlands. Weather measurements are local and time specific (hourly basis). As most commuters travel twice a day between home and work, we are able to...
