– Oak Ridge National Laboratory

INTRODUCTION

• SensorNet develop the Southeastern Transportation Corridor Pilot (SETCP).

• Purpose is to reinforce the inside interstate against illegal radioactive transportation.

• Three working station have the SETCP.– Kentucky– Tennessee– South Carolina

EXPERIMENTAL SETUP• Weigh Stations are checkpoints

along a highway.• Purpose is to inspect trucks weight.• Driver pull over for additional

inspection.• SensorNet added several devices.• Allowing the weigh station to detect

radiation in an automated way.

EXPERIMENTAL DIAGRAM WEIGH STATION

HardwareOptical Laser Scan – Used to detect occupancy of a vehicle upon entering the static scale. This scanner scans the axles on a semi truck to determine the number of axles, speed, truck configuration, and overall length of the vehicle..

Vehicle Classification and ConfigurationInfrared Camera – The infrared camera can be used for detection of bad brakes. Infrared can detect heat in locations where heat should not be or appears to be extreme. Indication of extreme heat has enabled the detection of bad bearings and broken springs and cracks in chassis frames.

Infrared Thermal Camera

License plate cameras with Optical Character Recognition (OCR) technology - Used to collect images of the front license plate on trucks entering the static scales. The OCR technology is important to allow easy database entry or inquiry.

License Plate CamerasRadiation Detection

Exploranium NucSafe

Radiation Portal Monitor -Radiation portal monitors can include Neutron and Gamma detection. Most of these systems are not designed to identify the radioactive isotopes. However, they can give Counts Per Seconds usually graphed by location on the vehicle.

DATA ANALYSIS

•During my internship I was responsible of:•Analyzing the data collected from the South Carolina station.

•Find patterns of radiation alarms and traffic flow.

•Analyze the SETCP viewer and identify inconsistencies.

OBSERVATIONS• Radiation Alarms were random.

Traffic Flow – May 2007

•Truck traffic is heavier Monday through Wednesday.•Dominant type of truck depends on location.

IMPROVEMENTS

• Length measurement improve by 35%.– WIM vs. Laser Scan Axle Counter

IMPROVEMENTS

• License Plate Reader• LPR accuracy improve by 46%.

– One camera for each half of the truck.

IMPROVEMENTS

• Optical Character Recognition

• Before OCR confused 36 characters.

• Now OCR confuse only five characters.

• “Alpha Zero” for personalize tags.Recorded Character

Actual Character

1 I6 GD 0O 0R 8

RECOMMENDATIONS

• Further analysis needs to be done.– To resolve the odd inconsistencies.

• “Over Load” yellow sign.• Ghost Truck.• Weightless Truck gets previous weight.

CONCLUSIONS

• The stations are functional.

• They detect the radiation and alarm authorities.

• Interstate are reinforced.

• Improvements were done.

• Fix of odd records will be done.
