Tidskriftsartikel (refereegranskat)abstract
- Urbanization and increasing road traffic cause exposure to both noise and air pollution. While the levels of air pollutants such as nitrogen oxides (NOx) have decreased in Sweden during the past decades, exposure to traffic noise has increased. The association with cardiovascular morbidity is less well established for noise than for air pollution, and most studies have only studied one of the two highly spatially correlated exposures. The Swedish Primary Prevention Study cohort consists of men aged 47 to 55 when first examined in 1970-1973. The cohort members were linked to the Swedish patient registry through their personal identity number and followed until first cardiovascular event 1970-2011. The address history during the entire study period was used to assign annual modelled residential exposure to road traffic noise and NOx. The Cox proportional hazards model with age on the time axis and time-varying exposures were used in the analysis. The results for 6304 men showed a non-significant increased risk of cardiovascular disease for long-term road traffic noise at the home address, after adjusting for air pollution. The hazard ratios were 1.08 (95% CI 0.90-1.28) for cardiovascular mortality, 1.14 (95% CI 0.96-1.36) for ischemic heart disease incidence and 1.07 (95% CI 0.85-1.36) for stroke incidence, for noise above 60 dB, compared to below 50 dB. This study found some support for cardiovascular health effects of long-term exposure to road traffic noise above 60 dB, after having accounted for exposure to air pollution.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThe aim of this study is to estimate monetary abatement values for road and rail traffic noise that can be used for policy purposes. However, a main objective is to critically discuss the assumptions necessary to convert the monetary values elicited in willingness to pay (WTP) studies to values than can be use for policy purposes.MethodsWe employ the hedonic regression technique on Swedish data to elicit individuals' preferences for noise abatement. Our elicited values are then converted to policy values and critically examined based on findings from a literature review.ResultsWe show that WTP for road and rail not only differs in levels but also that the relationship between the noise level and the marginal value differs between the two sources. We also show that a health cost component added to the WTP estimate, based on the assumption of uninformed property buyers, will be small but not negligible and that also modest differences in the assumption of the discount rates will have a significant effect on the estimated values.ConclusionsThe main implications from this study are: (i) WTP for road and railway noise abatement differs not only on absolute but also marginal levels, (ii) Even small differences in the chosen discount rate, which is necessary to convert WTP values from a hedonic price study to policy values, have large effects on the policy values, and (iii) We show how to add a health cost component to the WTP estimates in order for the monetary estimates to reflect the total social cost. However, we argue that the motivation for doing so is weak and that more research is needed on this issue.

Bulleravgift för järnvägsoperatörer : prissättning enligt marginalkostnadsprinciper
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Swedish Parliament has decided that, in order to mitigate externalities in railway infrastructure, operators in the Swedish railway infrastructure shall pay charges based on short-run marginal social costs. Internalization of the social cost from noise is of particular interest, since it is the only environmental problem which people perceive as more troublesome today than they did in the early 1990s. Inclusion of a noise component in rail infrastructure charges raises two problems: (i) the monetary evaluation of noise abatement, since noise is a non-marketed good, and (ii) the estimation of the effect on the noise level that one extra train will create. We are interested in the marginal noise, since infrastructure charges based on the short-run marginal cost principle should be based on the effect from the marginal train, not the noise level itself. We show in this study that, based on already obtained knowledge, it is possible to implement a noise component in the rail infrastructure charges. Those values that already today are used to estimate the social cost from noise exposure (which in Sweden are based on noise from road-traffic) in cost benefit analysis can also be used to calculate the marginal cost. We recommend, however, that further research is carried out in order to get more robust estimates and to get estimates based on railway traffic. We also show that the existing noise estimation models can easily be modified to estimate the marginal noise. Noise infrastructure charges give the operators incentives to reduce their noise emissions. We believe that this kind of charges can be used to reduce overall emission levels to an optimal social level, but that it is important that these charges are based on monetary estimates for rail-traffic and not road-traffic.

Bullervärden för samhällsekonomisk analys : beräkningar för väg- och järnvägsbuller
- 2009

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Noise is a significant social problem. For example, more than 20 per cent of the European Union's population is exposed to higher noise than what is considered acceptable. The transport sector is a major contributor to society's increasing noise problem, due to increased traffic volumes and urbanization exposing more people to noise. Road traffic is admittedly the largest individual noise source in the transport sector, but other transport modes such as aircraft and railways are also responsible for considerable noise emissions. Noise entails costs for the society. This fact, and that society has different needs, means that policies and projects to reduce noise levels need to be evaluated to secure an efficient resource allocation. Benefit cost analysis is a powerful tool to evaluate noise abatement, but it requires both benefits and costs to be measured in a common metric, i.e. in monetary values. Today's official monetary values for all modes are based on the impact of road-traffic noise on property prices. It is a well established fact that the disturbance which individuals experience differs between modes, and therefore there is a need to estimate monetary values based on the respective modes. This report focuses on road and rail noise, two noise sources with different characteristics. This study describes the need to revise the current official Swedish policy values for noise abatement. Current values for road-traffic noise show a progressive relationship between the social cost and the noise level that is too strong, and values for railway noise has been missing and instead based on results for road noise. Valuation of health effects should also be based on EKM since it is sanctioned within the EU, instead of the approach now proposed by ASEK based on estimated total social costs from noise exposure in relation to estimates from willingness to pay studies.

Charging the polluters : a pricing model for road and railway noise
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study outlines a method to estimate the short run marginal cost (SRMC) for road and railway noise. It is based on standardized calculation methods for total noise levels and monetary cost estimates from well established evaluation methods. Here official calculation methods and monetary values are used for Sweden, but the estimation method for the SRMC outlined can be directly applied using other standardized noise calculation methods and monetary values. This implies that the current knowledge regarding the calculation of total noise levels and the evaluation of the social cost of noise can be extended to estimate the marginal effect as well. This is an important finding since it enables policy makers to price noise externalities in an appropriate way. Several sensitivity tests run for the SRMC show that: (i) increasing the total traffic on the infrastructure has only a minor influence, (ii) estimates are quite sensitive to the number of exposed individuals, and (iii) to the monetary values used. Hence, benefits transfer, i.e. using monetary values elicited based on road noise for railway noise, should be done with caution or not at all. Results also show that the use of quiet technology can have a significant effect on the SRMC. The fact that this model is able to differentiate not only modes of transport, but also vehicles and even technologies is an important finding. It is essential that the noise charges give the operators the right incentives to choose their optimal allocation.

Tidskriftsartikel (refereegranskat)abstract
- By combining standardised calculation methods for total noise levels and monetary estimates from well-established evaluation methods, this study outlines a model to estimate the short-run marginal cost (SRMC) for road and railway noise that is able to differentiate not only modes of transport, but also vehicles and technologies. Several sensitivity tests run for the SRMC show that estimates are insensitive to traffic volume, sensitive to the number of exposed individuals, and sensitive to the monetary values used. Results also show that the use of quiet technology can have a significant effect on the SRMC.

Efterfrågan på tystnad : skattning av betalningsviljan för icke-marginella förändringar av vägtrafikbuller
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Efterfrågan på tystnad från vägbullerexponering skattas i detta projekt baserat på båda stegen i en så kallad hedonisk modell. Vi använder data från sju olika kommuner runt om i Sverige. Baserat på efterfrågekurvan kan vi räkna ut betalningsviljor för icke-marginella förändringar i bullerexponering från vägtrafik. Dessa resultat har stor användning i samhällsekonomiska kalkyler inom transportsektorn. Våra skattningsresultat visar att betalningsviljan för en bullerreducering från 66 till 65 dB är 2211 kronor per individ och år och 477 kronor per individ och år för en bullerreducering från 56 till 55 dB. Resultaten visar ingen betalningsvilja för bullerreduceringar under 52,8 dB. För en bullerreducering från 66 dB till 52,8 dB och alla lägre bullernivåer är betalningsviljan 15 225 kronor. Denna summa är även kostnaden för att utsättas för 66 dB vägbuller per individ och år.

Noise charges in railway infrastructure : a pricing schedule based on the marginal cost principle
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In order to mitigate the negative effects of transportation and to achieve a competitive transport sector, infrastructure charges in the European Union shall be based on short-run marginal costs. This paper shows that railway-noise charges can be estimated using already obtained knowledge of monetary and acoustical noise evaluation. Most European countries have standardised calculation methods for total noise level, which can be used to estimate the marginal acoustical effect. Based on a Swedish case study (with a relatively high number of exposed individuals), railway-noise charges are estimated at 0.026, 0.099 and 0.89 e/km for commuter, high-speed and freight trains, respectively.
