- switch means: end the current green phase and transition to the next green phase (in a fixed succession of phases) - timeHeadwayInApproach is the time gap between successive vehicles in lanes that have the green light in the current phase - delay in approach is the sum of delays incurred (due to standing or driving slower than the speed limit) by all vehicles in lanes that have the green light in the current phase
