To provide additional knowledge on the long term effects of railway and road traffic noise socio-acoustic surveys were performed in two residential areas exposed to road traffic noise (highway and major roads) and two areas exposed to railway noise (124 trains per day). Results were obtained for 974 individuals exposed to comparative sound levels ranging from LAeq,24h 45 to 65 dB. Road traffic caused significantly more noise annoyance than railway traffic, however, the difference decreased somewhat at higher sound levels above LAeq,24h 60 dB. For Lden the difference in annoyance between the two noise sources was larger and the difference increased at higher sound levels. At all sound levels, road traffic noise caused more disturbances of rest/relaxation (LAeq,24h) and sleep quality (Lnight) but less disturbance of conversation than railway noise. It was concluded that noise from railway traffic overall causes less adverse health effects than road traffic noise, in cases with a relatively moderate number of trains per day.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.



Modal shift for an environmental lift?

Investigations in Sweden and other countries suggest a shift of goods transport from road to rail and waterborne transport to reach environmental and climate objectives. VTI is leading a new project to investigate how the modal shift can contribute and what...


Automation and digitalisation are making rail competitive

Road transport is developing rapidly and its productivity has increased sharply. Rail transport, however, has not developed at the same rate. Automation and digitalisation are essential if rail freight in Europe is to survive.


New research is creating a driverless logistics chain

The research project Born to Drive has come up with a system that allows new cars to move, without a driver, from the production line out to the parking area prior to being transported elsewhere. The vision is to automate the entire logistics chain from...


VTI testing automation in EU project

VTI is leading a series of tests in a major EU project on automated driving. The first driving tests were carried out n a test track in Slovenia in December. The project will focus in part on acceptance among different groups in society, in part on...


Freight transportation on road and rail analysed

Freight transport accounts for a large proportion of the emissions, noise and congestion produced by road traffic. Transporting freight in larger but fewer lorries could reduce the problem. At the same time it might entail freight being diverted from more...


Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...
