Modified Model Predictive Control for Coordinated Signals along an Arterial under Relaxing Assumptions

Table 2

Assumptions and differences from typical assumptions.

ID	Assumptions	Differences
1	All streets are two-way, and traffic channelization is taken into account	Streets changed from one-way to two-way, and consideration of traffic channelization introduced
2	Traffic demand simultaneously takes into account both the vehicle demand and pedestrian crossing demand	Inclusion of pedestrian crossing demand in addition to vehicle demand
3	A dual-ring-barrier, eight-phase signal controller, as specified in the National Electric Manufacturers Association (NEMA) standards, is installed at every intersection	Transition from simpler signal controllers to more common types (NEMA standards) that support more phases and functions
4	The offset of every intersection is determined using alternative methods, taking into account the offset transition	Change in the determination of offset, now considering alternative methods and offset transition
5	The turning ratio randomly fluctuates within a certain range, and turning vehicles are not uniformly distributed over the link	Introduction of variability in turning ratios and non-uniform distribution of turning vehicles
6	Some of the vehicles entering the link cannot pass the stop line during the current cycle	Recognition that not all vehicles can pass the stop line during the current cycle, aligning with the practical reality that some vehicles must wait until the next cycle
