Traffic Signal “Synchronization”

This article discusses a city initiative to “synchronize” their traffic signals. As a traffic engineer, I try to avoid the term “synchronize” because that’s not what we do (I apologize if this is pedantic). To synchronize a signal network would cause all signals to be green or red or amber at the same time. What they mean is coordinate, and I heartily encourage them to do it. I only hope they realize that they have to maintain the coordination which requires funds for their signal engineers and technicians, indefinitely.
