Operational Efficiency Evaluation of Intersections with Dynamic Lane Assignment Using Field Data

Table 14

Paired -test results.

Lane	Paired differences						df	Sig. (2-tailed)
	Mean	Std. deviation	Std. error mean	95% confidence interval of the difference
				Lower	Upper
Group 1	0.003	0.032	0.015	−0.037	0.044	0.234	4	0.826
Group 3	−0.009	0.014	0.006	−0.027	0.009	−1.422	4	0.228

Note: group 1 and 3 are the variable lane and the adjacent lane with different lane-use (see Figure ).
