Olyckstypsklassificering: jämförelser i tid och rum

Jörgen Larsson

On behalf of the Swedish Institute for Transport and Communications Analysis SIKA, VTI has written a historic account of accident type classification in Sweden, and made a review of international recommendations and of the way in which a number of neighbouring countries perform their accident type classification. The retrospective review in Sweden extends to 1966 when the Swedish Council on Road Safety Research drew up a classification system. It was based on the situations and manoeuvres that preceded the accident and was thus a causal system. The system was however more detailed than the accident types which were presented in the official statistics. Over the years, minor changes were made to the accident types, certain events or conflicts were assigned to different accident types, as in the case of e.g. U turns, and accidents involving wildlife were made a separate accident type. Over many years, accident type classification was carried on by both the Swedish National Road Administration (VV) and Statistics Sweden SCB, but after 1994, when VV took charge of accident classification for the entire Swedish road network, the police in 1997 stopped direct reporting to SCB of road traffic accidents involving personal injury. VV was thus the only body that was responsible for accident type classification, and for some there had been a progressive increase in the automatic classification of accidents. When STRADA (Swedish Traffic Accident Data Acquisition) was introduced in 2003, accident types were given a consequence orientation (the way damage and/or injuries occurred). A few new accident types were introduced, but the names of the previous types were retained in spite of the fact that they no longer describe the same things as before.



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...
