Video in traffic

Modern video analysis techniques help to understand traffic better

Since the early 1980s when an intensive work on validation of the Swedish Traffic Conflict Technique started at Lund University, the idea of automation of video records analysis was in the air. Several generations of computer programs for working with video data have been developed and used in research, but none of them allowed eliminating the long hours of manual operator's work.

Now we have come as close as never before in reaching our goal - to develop an automated video analysis system for studying the traffic environment and road users' behaviour in it. The research team joins experts both in traffic and in image and video processing and focuses on the practical application of the video analysis techniques for the needs of traffic research.
