MIT engineers help fight roadside perils
Aim to cut crashes at traffic stops, accident scenes
John DiFava, a former Massachusetts State Police superintendent, is lucky to be alive. In 1976, an out-of-control vehicle nearly killed DiFava as he stood outside his patrol car on Interstate 495. “I was able to jump into the cruiser just in time,’’ said DiFava, who is currently chief of police at Massachusetts Institute of Technology.
