Tillståndsmätningar av vägmarkeringars funktion år 2012: sammanfattande resultat från Sverige

Mohammad Reza Yahya

This report summarizes the results of the condition assessment of road markings in Sweden 2012. The measurements have been carried out using the mobile system Road Marking Tester which mainly is built up of a reflectometer and an optocator. The two units register the retroreflectivity and the macro-texture of the road marking, respectively. From these measures, the retroreflectivity of a wet road marking can be predicted, which has been done on roads with ADT > 4000 vehicles. Measurements were accomplished on 292 objects in total, each approximately 10 km of length. The objects were chosen randomly and spread all over Sweden. In each object three longitudinal road markings were measured: two edge lines and one centre- or laneline.



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...
