Abstract
Video Detection has evolved from its infancy to a mature technology. Primary uses are to provide stop bar presence detection, and speed and volume detection on freeways as input to traveler information and freeway management systems. Video detection logic has traditionally operated with dedicated processor hardware and dedicated video cameras. Newer developments place the processing logic into the cameras, and CCTV cameras can be used to analyze video images in dedicated computers. This paper analyzes current trends in video detection, looking at new developments – providing an outlook to the future, where video detection plays a key role for infrastructureperformance measurement.
