Graphical Optimization Method for Symmetrical Bidirectional Corridor Progression

Table 2

The comparison table of the coordination effects of various models.

Model	Intersection	I1	I2	I3	I4	I5	I6	I7	I8
Proposed graphical method (MAXBAND model)	Coordinated mode	S	B	S	S	B	S	S	B
	Absolute offset (s)	63.8	17.6	59.4	59.4	17.6	59.4	57.2	22.0
	Common signal cycle (s)	88
	Bandwidth ratio (%)	37.3
Improved algebraic method	Coordinated mode	S	B	S	S	B	S	S	B
	Absolute offset (s)	66.0	18.2	61.4	61.4	18.2	61.4	59.2	22.8
	Common signal cycle (s)	91
	Bandwidth ratio (%)	30.5

S  = “synchronous coordinated mode” and B  = “backstepping coordinated mode”.
