The aim of this study is to estimate the price elasticity of demand for domestic air travel in Sweden. Using national aggregated data on passenger quantities and fares, price elasticities of demand are estimated with an unbalanced, in terms of stationarity, yet well performing model. The...

Usually transport systems, and roads in particular, are viewed as public goods. However, this is not always the case. In Sweden a large part of the road system is privately owned. Most of these privately owned roads are rural roads used by farmers and summer cottage owners, or used for forest...

A common approach for procuring large construction projects is through Unit Price Contracts. By the means of a simple model, we study the optimal quantity to procure under uncertainty regarding the actual required quantity given that the procurer strives to minomize expected total costs. The...

This paper studies the incentives for different countries to cooperate concerning pricing in transport systems, and how to handle the profit from such cooperation. Two types of simple networks with congestion are considered; one with parallel links, and one serial network with a number of...

The productivity of public infrastructure has been hte subject of jumerous studies during the last two decades, often with vastly differing results. Matters of concern for these estimates have been the level of aggregation of the data, the measurement of the infrastructure stock, and endogeneity...

The purpose of this paper is to analyze the climate benefit of investments in high speed rail-way lines given uncertainty in future transport demand, technology and power production. To capture the uncertainty of estimated parameters, distributions for the annual traffic emissions reduction...

Pedestrians are exposed to risks when crossing roads in urban areas. The crossing behaviour of pedestrians was studied as a factor contributing to their exposure to risks on the road and to their involvement in road accidents. This work explores two specific aspects of crossing behaviour:...

We estimate the value of time savings, different cycling environments and additional benefits in cost-benefit analysis of cycling investments. Cyclists’ value of travel time savings turns out to be high, considerably higher than the value of time savings on alternative modes. Cyclists also...

This paper compares the experience of three European countries with long experience of competition in rail transport – Britain, Sweden and Germany. Britain is characterised by complete separation of infrastructure from operations, competition either for or in the market for the entire...

Using a series of conventional large-scale household travel surveys conducted in the Osaka metropolitan area of Japan in 1980, 1990 and 2000 this study examines the mechanisms underlying children’s activity and travel engagements and how these mechanisms have changed over time. The results...
