Lesson

To improve the performance of freeway Wrong-Way driver detection systems, verify that articulating camera systems can consistently return to exact pre-set positions needed for analysis and automatically reset positioning if needed using reference points.

Florida DOT study evaluated the performance of Wrong-Way driver detection systems using video analytics.

Lesson Learned

  • Performance measures used were found to be excellent indicators of vendor freeway Wrong-Way driver detection, however real system performance should be further investigated based on actual Wrong-Way driving detection over a sufficiently long time, or under a controlled environment.
  • Existing Pan-Tilt-Zoom (PTZ) cameras were found to sometimes not return consistently to the exact pre-set position needed for analysis. As a result, fixed cameras were used for this study. The research team offered two recommendations: (1) Check PTZ cameras to determine if they can return to the exact pre-set position for similar studies, and (2) Improve freeway Wrong-Way driver detection systems to automatically adjust settings using reference points for minor movements of PTZ cameras and provide alerts for large movements.
