Traffic Safety and Behaviour

The research unit Traffic Safety and Behaviour deals with the subject of road safety in a broad context. The research activities cover subjects such as: statistical accident analysis and accident modelling; surrogate safety studies; behavioural and conflict observations; evaluation of road safety measures; issues regarding vulnerable road users including single fall accidents; microscopic simulations and their applications for safety studies; data quality and accident under-reporting issues.

ADAS – Advanced Driver Assistance Systems

The research area on Advanced Driver Assistance Systems comprises user related assessment of in-vehicle systems and the evaluation of the effects of such systems on driver behaviour, traffic safety, flow and the environment. Research is being/has been carried out within the framework of a number of nationally funded and European projects.

Surrogate measures of safety

Road traffic accidents are rather rare events. This is of course very positive but it also prevents accident data analysis from being an efficient tool in the local, every day traffic safety work. In addition, in many developing countries, accident data records are not reliable enough as a basis for assessment. The research group has a long and extensive experience of developing surrogate traffic safety measures as a complement to accident data. This work also involves research on validity and reliability, two basic requirements on surrogate measures. The Swedish Traffic Conflicts Technique was developed at the department. With emerging technologies such as image processing, it is possible to collect greater amounts of data and data that are more detailed. This enables the research group to continue developing and assessing new, and hopefully even better, surrogate traffic safety measures.

Walking and cycling

The transport policy goals, decided by the Swedish parliament, outlines the necessity to improve and thereby facilitate the possibility for people to choose the sustainable transport modes walk and bicycle. The research group contributes with research on pedestrians’ and cyclists’ comparatively high accident risks, evaluation of pedestrians’ and bicyclists’ infrastructure, and factors encouraging cycling and walking, etc.

Video analysis

Our goal is to develop an automated video analysis system for studying traffic environment and road user behaviour in it. The team joins experts both in traffic and image processing and focuses on practical application of the video analysis technology in traffic research.

The first attempts to analyse video were made in the early 1980s, when video recording was used in validation of the Swedish Traffic Conflict Technique (PDF). Several generations of computer programs for working with video have been developed and used, but none of them allowed us to eliminate the long hours of manual operator's work.

Co-operation with the Centre for Mathematical Sciences brought new life in this work, and help to make the system much more efficient and operator-independent.
