The Washington State Department of Transportation (WSDOT) has a network of several hundred closed-circuit television (CCTV) traffic surveillance cameras that are deployed for congestion monitoring on the freeways and arterials around Seattle. The goal of the first two phases of this project was to create algorithms that would allow these cameras to make continuous quantitative measurements of vehicle speed. In the first two phases, a number of algorithms were developed and tested; the most successful of these was chosen for implementation in this, Phase 3. The goal of this third phase was to implement the algorithms as prototype software.
