[31], we have mapped out the phase diagrams of traffic flow at an unsignalized intersection, by using the FI model. Thus, for the m = 1 case, the phase diagram is directly presented in Fig. 2(b) and is not discussed herein.

SpletWhen introducing actuation into the signal control, a Ring-and-Barrier structured traffic signal controller can be more flexible than stage-based controller by allowing different possible phase combinations. Example: In the above NEMA diagram, we could see phase 1+5, 1+6, 2+6, 3+7, 3+8 and 4+8. However, when the traffic on phase 1 is very low ...
