INTRODUCTION Summer Internship –DOE/FIU Science & Technology Workforce Development Initiative –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
SOFTWARE Southeastern Transportation Corridor Pilot Viewer
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 1I 6G D0 O0 R8
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.
