(3) Wide moving jam. In the three-phase traffic theory, features of spatial–temporal congested patterns are explained based on the phase transitions between these three traffic phases. 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.
