• Abstract:
  A video image detection system (VIDS) is an advanced wide-area traffic monitoring system
  
  that processes input from a video camera. The Autoscope VIDS coupled with an information
  
  management system was selected as the monitoring device because testing had shown it to
  
  be the most advanced system available with respect to performance, reliability, and accuracy.
  
  The purpose of this project was to evaluate the capabilities of the VIDS. The primary
  
  objective was to assess the performance of the VIDS for incident detection, and a secondary
  
  objective was to examine its capability to monitor traffic. Existing hardware was to be used for
  
  the VIDS as much as possible in order to fit the VIDS into the existing TMS Center operations
  
  and to minimize additional costs.
  
  Based on an evaluation that focused on traffic monitoring, the VIDS performed unsatisfactorily
  
  at two sites and satisfactorily at a third site. The location of the video camera relative
  
  to the monitoring site, which is critical to effective operations of the VIDS, was the major cause
  
  of the unsatisfactory performance. The primary objective was not achieved. The potential for
  
  using the Autoscope at existing camera locations in Northern Virginia is limited. Based on the
  
  performance of the Autoscope at the Woodrow Wilson Bridge, it was concluded that it is difficult
  
  to accurately return an Autoscope camera to its monitoring position after it is moved for surveillance.
  
  A dedicated camera is necessary for the VIDS.
  
  Recommendations were made for the use of the VIDS and for project planning and contract
  
  administration for future projects of this nature.
