Cost benefit analysis of video-based vehicle detection

The need for advanced traffic detection devices that reduce installation and maintenance costs while extracting more traffic flow measurements has lead to the development of machine vision, wide-area detection systems. Machine vision provides "above road" detection and wide-area measurements that replace many conventional inductive loop detectors. Lane closure costs for loop installation and maintenance are effectively eliminated. In addition, the detection performance is easily verified and detectors are easy to reconfigure interactively.
