Belt Shift Interlock Delay/Deaccelerator with Learning Curve Software to increase Seatbelt Usage on commercial Vehicles

Various methods for increasing seat belt usage have been investigated over the last several years including visual and audible warnings currently installed in today's vehicles. In spite of these attempts, FMCSA research has shown that drivers of about 59% of commercial motor vehicles (those weighing over 10,000 pounds or more that operate in interstate commerce) buckle their safety belts as compared to about 82% of passenger vehicle drivers. Proposed methods for inhibiting vehicle drivability are out of the question for obvious safety and liability reasons. A more reasonable and subtle approach would be to alter driver behavior. The Center for Education and Research in Safety, working in conjunction with the Tenik Group, Inc., has recently concluded a 100 commercial vehicle study, through NHTSA at the DOT, using an 8 second belt shift delay device combined with "Learning Curve" software. The results of this study have shown a 45% increase in seatbelt usage. Another preliminary test using a prototype "Deaccelerator Force Feedback" device has also proven to be effective in increasing belt usage. Improved "Learning Curve" software in combination with the belt shift interlock delay, the "Deaccelerator Force Feedback" or possibly using both devices should further increase belt usage in commercial vehicles.
