Cyklisters singelolyckor: analys av olycks- och skadedata samt djupintervjuer


The objective of this project was to study single bicycle accidents, to see how these can be avoided and how the injuries due to these can be alleviated. The in-depth studies of fatal accidents by the Swedish Traffic Administration, and hospital reported accidents in the database Strada have been analysed. The focus was on the single bicycle accidents resulting in death or serious injury, and the data for 2007-–2011 were included. In addition, 32 seriously injured cyclists were interviewed about the accident in which they had been involved. Of all the cyclists who need emergency treatment, eight out of ten had been injured in a single accident. In addition, on average five cyclists were killed every year in a single bicycle accident. In all, during the five-year period studied, 125 cyclists were killed. Of the 1,274 seriously injured in single bicycle accidents, 27 per cent can be related to operation and maintenance, 20 per cent to road design, 27 per cent to cyclist-bicycle interaction, 15 per cent to the behaviour and state of the cyclist, and 11 per cent to the interaction of the cyclist with other road users. Older age groups are involved to a greater extent than the young, in both the fatal accidents and the serious accidents – more than 40 per cent among those killed and seriously injured were 65 or older. The serious injuries among older people are characterised by injuries to the hips. In other respects, head injuries dominate among the seriously injured cyclists, and head injuries were the cause of death in 70 per cent of single bicycle accidents.

Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...


New climate-proof solutions for hard surfaces in cities

High-density road infrastructure that emphasise maximum durability and minimum maintenance create inflexible systems, which put increased stress on urban trees and lead to increased risk for flooding. Over the past five years, the ‘Climate-proof solutions for...


VTI is preparing for automated vehicles

Automation of traffic systems will lead to major changes. The European Union’s (EU) CoEXist research project began in June 2017 with the aim of preparing cities and road operators for the introduction of self-driving vehicles. The Swedish National Road and...


Vehicle Driver Monitoring: sleepiness and cognitive load

To prevent road crashes it is important to understand driver related contributing factors, which have been suggested to be the critical reason in 94 per cent of crashes. The overall aim of the project Vehicle Driver Monitoring has been to advance the...
