WebDesign engineers should use the NEMA phasing pattern to number the phases. The left-side intersection is assigned Phases 1 to 4, and the right-side intersection is assigned Phases 5 to 8. While the arterial approaches are numbered as Phase 2 and Phase 6, the internal left-turn movements are numbered Phase 1 and Phase 5. WebThe signal phasing sequence is specified by clicking on the Quick Phases dual-ring (NEMA) phasing diagram (phases 1 through 8). Only left-turn phasing needs to be set, because thru movements and right-turn movements are automatically added to the phasing sequence as a function of laneage. cnb production
