Hållbara turistresor: en fallstudie av destinationerna Kiruna, Åre, Sälen och Vimmerby

In conjunction with development of destinations and transport systems, tourist demands and requirements are essential in determining measures and changes that may lead to more sustainable travel. Different options for travel to and from destinations...

Hållbara turistresor i samhällsekonomisk analys

Statistics show that tourism in Sweden is increasing, thus increasing its importance for the overall economy, exports and employment. However, tourism is also associated with environmental and other effects, for example from tourist travel. This...

Elanvändning för längre och tyngre tåg: sammanfattning av resultat, erfarenheter och...

The ELVIS demonstration project aims to analyze how rail freight transports can be performed more efficiently. Hypotheses are that the transport efficiency can be improved by using longer and heavier freight trains and by implementing energy-related...

Internalisation of external effects in European freight corridors

This project was conducted upon a request from the Swedish Agency for Transport Analysis (Trafikanalys), with a governmental assignment to annually report the rate of internalisation per mode for passenger and freight transports. In its 2013 report,...

Internalisation of External Effects in European Freight Corridors

External effects or externalities “consist of the costs and benefits felt beyond or ‘external to’ those causing the effect” (Anderson, 2006). In the case of transportation, the negative externalities (costs) can take the form of air pollution, noise...

Allocation of user benefits for international freight transports: in cost-benefit analysis

The aim of this project is to analyse when, if and how a transport cost reduction, following an infrastructure investment affecting international freight transports, should be allocated between countries in a cost-benefit analysis (CBA). In order to...

Differentierade marginalkostnader inom järnvägen

In Sweden, pricing within the rail sector should mainly depart from the principles of marginal pricing. The pricing mechanism should be designed so that the negative external effects are compensatedthrough taxes and charges. Today, the track charges...

Strategi för utveckling av en samhällsekonomisk analysmodell för drift, underhåll och...

The ability to make structured decisions about the optimal funding for operation, maintenance and renewal of roads and railways is currently limited. This creates significant risks that the funds are used in an inefficient manner. It is therefore...

Estimating the marginal cost of railway track renewals using corner solution models

Economic theory advocates marginal cost pricing for efficient utilisation of transport infrastructure. A growing body of literature has emerged on the issue of rail marginal infrastructure wear and tear costs, but the majority of the work is focused...

The marginal cost of railway track renewals: a sample selection modelling approach

Economic theory advocates marginal cost pricing for efficient utilisation of transport infrastructure. A growing body of literature has emerged on the issue of marginal infrastructure wear and tear costs, but the majority of the work is focused on...
