• 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.
