The Swedish Road and Transport Research Institute (VTI) has studied the effects of measures taken on the street network in five towns. The effects studied were safety, trafficability and environmental impact (as the effect of gas, particle and noise emissions). The measures taken were physical measures with the principal purpose of reducing vehicle speeds and reducing the distance over which pedestrians and cyclists were exposed. The levels of intersections were raised, pinch points or chicanes were constructed along streets, different types of surfacings were laid in order to reinforce the perception of a reduced street space. Before and after studies were performed. The sites were videoed. The results of this formed the basis for assessing the safety effect and determining trafficability and vehicle flows. The video footage was also used to determine the speed distribution of vehicles on pedestrian and cycle crossings. The driving pattern of vehicles was studied with the help of the pursuit vehicle at some of the sites in order to determine the speed reducing effect of the measures along the street. The gas and particle emissions of vehicles were estimated using the VETO model. This model was also used to make an advance estimate of the effect of the measures on traffic noise. Attitude surveys were conducted at the sites to determine the opinions of road users concerning the measures.



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...
