Could it be connections to other nearby signals for synchronizing the lights?

- greenyoda 8y agoAlso possibly a connection to a central traffic control center that can override signals during emergencies or special events that generate abnormal traffic flows.
- JdeBP 8y agoI mentioned SCOOT elsewhere in this discussion. With such systems, overriding is (I was told) the norm. The isolated controller on fixed timing is the fallback case.
