Our task here will be to compare these results to see which combination provides the better overall efficiency. We can make two runs: one with all actuated movements, arrival types of 3 and unit extension values of 3.0 seconds, and the other with eastbound through movements and westbound through and right-turn movements coded as pretimed, using arrival types of 4, with the unit extension values to be ignored. The results of these two runs are presented in the following table to compare the affected approaches and the overall intersection operations:

Comparison of Fully Actuated to Semi Actuated Control
	Fully Actuated			Semi-Actuated
	EBT	WBT	WBR	EBT	WBT	WBR
Volumes	670	597	178	670	597	178
Arrival Type	3	3	3	4	4	4
Progression Factor	1.00	1.00	1.00	0.24	0.44	0.44
d₁	6.0	15.1	15.1	5.6	13.2	13.2
PF * d₁	6.0	15.1	15.1	1.3	5.8	5.8
Unit Extension	3.0	3.0	3.0	-	-	-
k-Value	0.11	0.27	0.27	0.50	0.50	0.50
d₂	0.3	2.0	2.0	1.2	3.1	3.1
Movement Delay	6.2	17.2	17.2	2.5	8.9	8.9
Movement LOS	A	B	B	A	A	A
Intersection Delay	22.0			16.6
Intersection LOS	C			B

As you can see, the unit extension creates k-values of less than 0.50, which lowers d₂. But, arrival type values of 3 result in progression factors of 1.00, with no effect on d₁. However, under semi-actuated control, the k-value stays at 0.50, not affecting d₂, but the progression factor is lower which reduces the d₁ term. Overall, we can see that the combined effects of semi-actuated control on the d₂ term outweigh those of fully-actuated control on the d₁ term.
