Application of VADAS to complex traffic environments

Data, collected correctly and analyzed systematically, provide a solid basis for understanding the traffic system. This paper discusses recent developments in the collection and analysis of video data. It is particularly directed towards applications in low-speed environments: car parks and pedestrian crossings. The paper discusses the collection of data on behavior, speed, travel time, headway, parking-duration, and parking (and un parking) times. It concludes that video enables the accurate determination of changes in maneuvers, removes errors due to the reaction time of the observer, provides a permanent record for repeated analysis, enables the impact of remedial measures to be observed, and, when combined with automatic detection procedures, allows considerable reductions in data extraction times.
