7 System Level Performance

Traffic monitoring system is capable of detecting, and tracking targets at EVM, sending targets list to a Host PC for scene interpretation and visualization.

To asses system level performance of traffic monitoring system we construct appropriate test cases, record ground truth, and compute:

  • accuracy of vehicle counting
  • vehicle tracking reliability
  • vehicle location estimations precision
  • vehicle velocity estimation precision
  • vehicle detection distance

Summary of performance results is presented in the table below. The test case and methodology on how we computed those values is explained in the subsections that follow.

PARAMETER DIMENSION MEASURED VALUE SECTION
Vehicle Counting Reliability % 97.8 7.1
Vehicle Tracking Reliability % 86.2 7.2
Vehicle Location Precision m Xpos = 0.23, Ypos = 0.48 7.3
Vehicle Velocity Precision m/s Vx = 0.63, Vy = 0.44 7.4
Vehicle Detection Distance m 54.7 (mean), 72.1 (max) 7.5
