Explain the Signalized Intersections

Cycle length - the time required for one complete sequence of all signal indications

Phase - the right-of-way (green), change (yellow), and clearance (all red) intervals in a cycle that are assigned to an independent traffic movement or combination of movements

Green interval - the right-of-way interval during which the signal indication is green

Yellow Change interval - the first interval following the green interval or which the signal indication is yellow

Clearance interval - an interval that follows a yellow change interval and precedes the next conflicting green interval
