In contrast to computerized signal controllers, electro-mechanical signal controllers are mainly composed of movable parts (cams, dials, and shafts) that Regulate signals that are wired to them specifically. Apart from movable parts, electrical relays are employed. Generally, electro-mechanical signal controllers use dial timers which have set, signalized intersection time options. Cycle lengths of signalized intersections are determined by smaller gears that are located within just dial timers.

These signal lights are programmed to prevent conflicts in between road end users though letting traffic to maneuver through the intersection as freely as feasible. This information will train you the way to interpret traffic lights.

Farside signals are located over the crossing, whilst nearside signals are located beneath the traffic lights, facing during the direction of oncoming traffic.[19]: c.18  A HAWK beacon is often a Particular sort of traffic Utilized in the US at mid-block crossings.
