• Abstract:
  The work accomplished under this initiative is in direct relation to the development effort proposed by Spectra
  
  Research, Inc. (S*R) for an "Off-Road Axle Detection Sensor (ORADS)". The feasibility study was performed to
  
  investigate potential occlusions that may arise from the use of a laser-radar (LADAR) based sensor configuration.
  
  This feasibility study was suggested to determine any potential risk in the development.
  
  S*R was awarded a contract to perform video analysis work over a six month period. S*R performed video tests to
  
  visually inspect situations under which occlusion may occur during peak, unidirectional traffic flow on a highly
  
  populated, multiple lane interstate. The test site was selected by ODOT representatives, 1-275 northbound at exit
  
  46 during peak traffic times (4-6 p.m.). Data was collected for approximately one hour using two video cameras.
  
  Camera 1 was used to record on-coming traffic for lane and volume data. Camera 2 was positioned to act as the
  
  LADAR sensor to provide axle count and occlusion data.
  
  The results of this effort show that across a multiple lane roadway exhibiting high volume traffic flow, the
  
  aggregate probability of axle occlusion is 4.21%. These results were anticipated and conform to the error
  
  requirements ( 4 0%) identified by ODOT officials. Recommendation is made for further funding of the ORADS
  
  Phase II development.
