Road traffic conflict analysis from geo-referenced stereo sequences

In this paper an imaging system for road traffic conflict analysis is proposed. The system exploits geo-referenced stereo sequences and tracking procedure to compute traffic conflict measures which can be analysed by experts. Using the potentiality of the traffic conflict technique as a surrogate safety measure could constitute an effective tool in understanding how the driver interacts and adapts its behaviour with respect to the vehicle, the road characteristics, the traffic control devices and environment. Experiments performed on real data acquired in urban environment confirm the effectiveness of the system which makes simple and fast for the experts the understanding of the driver behaviour.
