In 1959, Robert Herman, a researcher at the General Motors Technical Center in Warren, Michigan, received a ticket for running a red light. Herman felt that the yellow signal time was "too short," causing him to violate the law, and that the ticket was unfair. He enlisted the help of two of his colleagues at the Technical Center, Denos Gazis and Alexei A. Maradudin, in analyzing the following problem: What is the minimum yellow interval necessary to ensure that a driver, approaching a signalized intersection, does not encounter a "dilemma zone," where a driver could neither STOP safely and comfortably, nor GO without the need to violate the red or accelerate into the intersection? |
