Transportation practitioners, planners and researchers lack the availability of an easily
deployable, non-intrusive, portable, low-cost device for traffic data collection and video
recording at intersections and arterials as well as temporary remote surveillance. The
necessary data usually includes volumes, speeds, classification, turning movements,
queue size and length, conflicting movements, time headways and vehicle delay. They
also include recording of traffic characteristics, accidents and other special situations. A
visual record of traffic characteristics at intersections, arterials, or other locations can also
be used for extensive analysis and research leading to improved safety and control
practices. In this thesis, the development and demonstration of a low-cost, practical,
rapidly deployable video recording and data collection device is presented along with the
design, deployment, and data extraction process. Its major advantage at intersections is
that only one unit can cover an entire intersection up to 5 lanes per incoming approach
wide (20 incoming lanes total), which should be sufficient for the overwhelming majority
of intersections. In addition it has the potential of extracting turning movements
automatically including optional lanes through advanced machine vision or radar sensors.
