Although roll-over protection systems (ROPS) are now mandated for farm tractors, tractor overturns cause approximately 400 deaths per year in the United States. This project will focus on new cost-effective combinations of sensors and microprocessors to detect impending side overturn, overturn of tractors with attached implements and operator display ergonomics and psychology.
