… or lane groups, the lane-based model for platoon movements between upstream and downstream Sites (on internal approaches) takes into account midblock lane changes that apply to second-by second platoon patterns. This is particularly important in evaluating closely-spaced (paired) intersections with high demand flows where vehicles have limited opportunities for lane changes between intersections. Midblock inflows and any interruptions due to queues of midblock opposed turns result in uniform flow patterns that disrupt good signal …
