Strong point out controllers are necessary to have an impartial conflict watch device (CMU), which guarantees fail-Protected Procedure. The CMU screens the outputs on the controller, and when a fault is detected, the CMU takes advantage of the flash transfer relays to put the intersection to FLASH, with all purple lights flashing, instead of displaying a most likely dangerous mix of signals.

"Phases" (or "signal groups" in Australia and New Zealand) are indications demonstrate at the same time, e.g. many eco-friendly lights which Regulate precisely the same traffic method.

A stage (or "section" in ANZ) is a bunch of non-conflicting phases which move at the same time. The stages are collectively often known as a "cycle".[sixty four] Time in between two conflicting environmentally friendly phases is known as an "intergreen time period", which can be set at an suitable length with the junction to safely and securely very clear, specifically for turning traffic which may be ready while in the centre with the junction.
