Most people call the traffic lights "timed" when if you drive at the posted speed limit you will get all green lights. In the business (by the business I mean the industry) we call those "interconnects". There is a communication wire that "interconnects" one intersection to the next.

We refer to them more commonly as nouns (We are going to install five interconnects along this stretch of Main St.) rather than adjectives. (These 10 signals are interconnected.)
