Abstract:The Smart InfraRed Inspection System (SIRIS) is a tool designed to assist inspectors in determining which vehicles
passing through the system are in need of further inspection by measuring the thermal data from the wheel
components. As a vehicle enters the system, infrared cameras installed on the road measure temperatures of the
brakes, tires, and wheel bearings on both wheel ends of commercial motor vehicles (CMVs) in motion. This thermal
data is then presented on a user-friendly interface to enforcement personnel in the inspection station. Vehicles that
are suspected to have a violation are automatically alerted to the enforcement staff.
The main goal of the SIRIS field operational test (FOT) was to collect data to evaluate the performance of the
prototype system and to determine the viability of such a system being used for CMV enforcement.
Overall, the enforcement personnel who have used SIRIS for screening purposes have indicated that SIRIS has the
potential to be an effective tool. With improvements in detection algorithms and stability, the system will be
beneficial to the CMV enforcement community and will increase overall trooper productivity by accurately
identifying a higher percentage of potentially dangerous CMVs for inspection.
