The optimal velocity model is a simplest one of the fundamental models. The model exhibits two traffic phases. However, one will obtain the multi-phase traffic theory by extending the optimal velocity model.

Lagging left turn phase When specifying lagging phases in TRAFED, the phase boxes are not rearranged as illustrated above. Rather, the analyst must select the phase order for each of the phase pairs, 1 and 2, 3 and 4, 5 and 6, 7 and 8 on the Phase Sequence tab of the actuated control interface.

SpletTwo phase system is usually adopted if through traffic is significant compared to the turning movements. For example in figure 2, non-conflicting through traffic 3 and 4 are grouped in a single phase and non-conflicting through traffic 1 and 2 are grouped in the second phase. Figure 2: Two phase signal Spletwork well for these complex situations. The solution is to draw a Traffic Signal Head Phasing Diagram/Table. The diagram can be drawn in existing traffic signal diagram, just by adding a few notations on the side of signal heads explaining the phase number or overlap number for that signal head’s Red, Yellow, Green Arrow and Green Ball.

SpletThis paper uses empirical traffic data collected from three locations in Europe and the US to reveal a three-phase fundamental diagram with two phases located in the uncongested regime.
