The influence of demand incentives in public transport contracts on patronage and costs...

The objective to reduce carbon emissions has inspired Swedish regional public transport authorities (RPTA) to adopt a goal of doubling public transport patronage from 2006 to 2020. Several measures have been used to achieve this goal. Increasing the...

Distributional effects of taxes on car fuel, use, ownership and purchases

We analyse distributional effects of four car-related tax instruments: an increase of the fuel tax, a new kilometre tax, an increased CO2-differentiated vehicle ownership tax, and a CO2-differentiated purchase tax on new cars. Distributional effects...

Estimation of the marginal cost for road noise and rail noise

The purpose of this study is to estimate the marginal cost of road noise and rail noise in Sweden. We use the impact pathway approach (IPA) where traffic noise exposure implies an impact on individuals, which in turn is related to monetary valuation...

Marginal cost of road maintenance and operation: Swedish estimates based on data from...

In this study, we estimated the marginal costs of road operation and maintenance by using the cost function approach with Swedish road network data from 2004 to 2014. The results of this study suggest a marginal cost of 0.07 SEK per vehicle...

The influence of public transport supply on private car use in 17 mid-sized Swedish...

We analyse the impact of increased public transport supply on private car use using micro data on individuals from 17 mid-sized cities in Sweden. The data is obtained from Swedish administrative registers (tax and odometer), which exists for all...

Differences in the effects of fuel price and income on private car use in Sweden 1999-2008

The objective of this paper is to analyse how the use of privately owned cars in Sweden varies across a number of background parameters including fuel price, disposable income, car purchase cost index, children over 18, employment and the car...

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...

Externa kostnader för luftföroreningar och buller från trafiken på det statliga vägnätet:...

In December 2012, the Swedish government commissioned VTI to update the social marginal cost for using infrastructure for all modes of transport based on state-of-the-art knowledge in the research community. The task only involved state roads. In...

Traffic noise effects of property prices: hedonic estimates based on multiple noise...

Valuation of traffic noise abatement based on hedonic pricing models of the property market has traditionally measured the noise as the equivalent, or another average, level. What is not captured in such a noise indicator is the maximum noise level...

Värdering av komfort och minskning av trängsel i kollektivtrafiken: en sammanfattning

This report is a Swedish summary of: Björklund, G. & Swärdh, J-E. (2015). Valuing in-vehicle comfort and crowding reduction in public transport. CTS Working Paper 2015:12. http://swopec.hhs.se/ctswps/abs/ctswps2015_012.htmThe purpose of the present...

Willingness to accept commuting time within the household: stated preference evidence

In this study, stated preference data is used to derive estimated values of commuting time (VOCT). Both spouses in two-earner households are individually making trade-offs between commuting time and wage; both with regard to their own commuting time...

Regelförändringar i transportsektorn – effekter av omregleringar inom inrikesflyg, taxi,...

Konkurrensverket (the Swedish Competition Authority) has commissioned the Swedish National Road and Transport Research Institute (VTI) to provide an overview of the consequences of four regulatory reforms in the transport sector during the past 20...

The value of commuting time in an empirical on-the-job search model: an application based...

This article estimates the Value of Commuting Time (VOCT) among Swedish males in an empirical on-the-job search model. It uses a large sample of employee-establishment linked data obtained from administrative registers. The sample lacks information...

Fyrstegsprincipen i praktiken: tre underlagsrapporter för Riksrevisionens granskning av...

Sweden’s parliament and its government have access to a number of means for implementing overarching policies, inter alia in the transport sector. There is a broad consensus that the four step principle should provide the basic logic for choice of...

Noise charges for Swedish railways based on marginal cost calculations

This paper describes an effort to calculate marginal costs for railway traffic in Sweden using 1) standardised and already well established methods for calculating noise and 2) valuations of noise based on hedonic regression. The main point is that...

Estimating non-marginal willingness to pay for railway noise abatements: application of...

In this study we estimate the willingness to pay for railway noise abatements based on the effect of railway noise on property prices. We estimate both steps of the hedonic regression technique on a large data set of different Swedish regions which...

Commuting time changes following residential relocations and job relocations

This paper focuses on empirical analysis of commuting time changes for workers who relocate residence, relocate job, or combine both residence and job relocation. A large register data set of individuals on the Swedish labor market, including travel...

Willingness to accept commuting time for yourself and for your spouse: empirical evidence...

In this study, Swedish stated preference data is used to derive estimated values of commuting time (VOCT). Both spouses in two-earner households are individually making trade-offs between commuting time and wage; both with regard to their own...

Hypothetical bias and certainty calibration in a value of time experiment

This study is the first to analyze hypothetical bias in a willingness to pay for time context as well as the first to test certainty calibration of the value of time. Hypothetical and real actions are compared in an experimental setting where the...

Is the intertemporal income elasticity of the value of travel time unity?

The purpose of this study is to estimate the intertemporal income elasticity of the value of travel time (VTT) and test whether it differs from one. The empirical analysis is performed on Swedish revealed preference data, where voluntary job...

The value of time from subjective data on life satisfaction and job satisfaction: an...

This paper compares estimates of the value of commuting time, working time and household working time from empirical models of subjective assessments of life satisfaction and job satisfaction, respectively, to the corresponding estimates obtained...

An empirical on-the-job search model with preferences for relative earnings: how high is...

The purpose of this paper is to estimate the average value of commuting time (VoCT) in an empirical on-the-job search model. A large Swedish sample of employee-establishment linked data obtained from administrative registers is used to this end. The...
