Rullmotstånd: vägytans egenskaper och dess inverkan


Rolling resistance is an important aspect of the road surface properties in relation to transport energy use and emissions of carbon dioxide (CO2). By reducing rolling resistance, the transport energy efficiency can be improved and the CO2 emissions can be reduced. This will help in reaching the climate targets. MIRIAM is a joint project with partners from Europe and the United States with the aim to provide better opportunities to control road transport CO2 emissions related to road surface characteristics with focus on reducing rolling resistance. The partnership covers measurement methods and equipment, tests and measurements, modeling, case studies and implementation of results.

The purpose of this report is to provide an overview of the results published in MIRIAM. The report will give a description of what has been done in the different sub-projects and what the findings are. The compilation is based on the reports and other publications issued within MIRIAM as well as in projects that directly is connected to MIRIAM, and that is published on their websites.



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.



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...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...
