In 2012, there were 1.7 million rear-end crashes. That’s what a special report by the National Transportation Safety Board (NTSB) revealed. The number represents almost half of two-vehicle crashes, and what’s most shocking is that these crashes resulted in 1,705 fatalities and more than a half million injuries. Why? Reasons include driver inattentiveness, fatigue, and reduced visibility. In short, drivers could not identify and respond to conditions quickly enough. As engineers, it is our job to seek solutions to problems like this. By Girma Tewolde Professor of Electrical and Computer Engineering at Kettering University 16 17
