Health impact, does it influence the acceptance for road pricing?

Year:
2007
VTI-code:
R582

Authors: Lena Nerhagen

Road traffic makes important contributions to the pollution levels in urban areas. Of the pollutants, particulate matter makes the greatest contribution to the external cost due to their detrimental impact on human health. Economic policy measures such as road pricing can be used for the regulation of traffic, thereby improving local air quality, but there is often a large resistance towards these types of policy measures. One reason for this could be that the impact and health effects are not well known to the general public. Hence, this aspect is likely to be of little importance for the ...

Noise emission from railway traffic

Year:
2007
VTI-code:
R559A

Authors: Mikael Ögren

European authorities hope to be able to increase the volume of freight and passengers that are transported on railway systems compared to those transported on roads. If that policy is successful the problem of noise from railway traffic will increase. It is known
from previous research that measures against the noise are more efficient if applied directly at the source itself rather than using indirect measures such as noise barriers and increased window insulation. This report is a literature survey on how the railway noise is generated, and to what extend different measures at the ...

The Winter Model, Stage 2. Final report

Year:
2006
VTI-code:
R531

Authors: Mats Gustafsson , Göran Blomqvist , Anna Niska , Bo Karlsson , Carl-Gustaf Wallman , Gudrun Öberg , Carl Magnus Berglund , Staffan Möller

The aim of the Winter Model is to estimate and put a value on the most important impacts of the strategies and measures in winter road management for road users, road management authorities and society at large. The main report itself is a summary of the reports that describe the submodels in the Winter Model.
The hub of the model is the Road Condition Model which, on the basis of weather data, undertaken road management measures and traffic, calculates road conditions hour by hour during the winter season. The Road Condition Model controls calculations in the effect models: Accident ...

Habitat fragmentation due to transportation infrastructure. COST 341 national state-of-the-art report Sweden

Year:
2006
VTI-code:
R530A

Authors: Lennart Folkeson , Andreas Seiler

The publication has been edited by Andreas Seiler and Lennart Folkeson.

Fragmentation of landscapes and habitats is a major cause of the impoverishment of biodiversity in Europe. Transportation infrastructure, notably roads and railways, strongly contribute to the fragmentation. This is an important issue in infrastructure planning in the densely populated countries in Europe. Increasing attention is being paid to landscape fragmentation also in Sweden.
Landscape fragmentation comprises the splitting of habitats and ecosystems in smaller and more isolated units. Habitat loss ...

Methods for synchronizing driving patterns and emission data

Year:
2006
VTI-code:
R525

Authors: Rune Karlsson

A well-known problem in modal measurements of emissions of gasoline-powered cars is the lack of synchronism between engine data and emission data. The main difficulty when trying to eliminate this problem is to determine the time required by the exhaust gas to move from the cylinder to the trailing edge of the exhaust pipe. This time delay can vary several seconds depending on the engine speed and load and also on the volume of the exhaust system.
We discuss a number of conceivable approaches to compute this time delay. Three proposed methods have been investigated in more detail. The ...

Effects of winter tyres – state of the art

Year:
2006
VTI-code:
R543

Authors: Ulf Sandberg , Mats Gustafsson , Ulf Hammarström , Inger Forsberg , Mattias Hjort , Sonja Forward , Olle Nordström , Mats Wiklund , Gudrun Öberg , Stefan Grudemo , Carl Magnus Berglund , Torbjörn Jacobson , Bertil Forsberg , Christer Johansson

Choice of winter tyres has, from mainly being a matter of safety and economic costs for wearing of road pavements, during later years also become a matter of inhalable particles formed during pavement wear from studded tyres and their negative effects on public health. Further, the tyres’ effects on environment and noise have been illustrated in several studies. The issue is also complicated by the fact that tyre choice effects on traffic safety have several components, including such diverging parameters as friction and behaviour. Finally all aspects have to be evaluated from a socioeconomic ...

Inhalable particles in railroad environments

Year:
2006
VTI-code:
R538

Authors: Mats Gustafsson , Göran Blomqvist

Airborne particles from railroad traffic have been identified as an air pollution problem
mainly in tunnel environments. In several subways around the world, the smell of brake
dust and high particle concentrations have focused attention on the sources of the
particles and the measures that can be taken to reduce emissions. But problems have
also been identified in railroad environments above ground. For instance, dust
deposition has been accused of damaging the enamel on cars parked closed to the
railroad. The deposition has been studied in a previous VTI ...

Noise Charge for rail operators

Year:
2006
VTI-code:
N7-2006

Authors: Mikael Ögren , Henrik Andersson

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 ...
