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

Table 1

Basic geometry information of the surveyed intersections.

Number	Intersection	Leg using the dynamic lane assignment	Number of approach lanes	Lane assignment of the approach lanes
				Lane 1	Lane 2	Lane 3	Lane 4	Lane 5
1	Caoxibei Rd.-Lingling Rd.	North	3	LT	Variable	TH
2	Tianyaoqiao Rd.-Zhongshan Rd.	North	4	LT	Variable	TH	RT
3	Yanggaonan Rd.- Huamu Rd.	South	5	LT	Variable	TH	TH	TH + RT
4	Yanggaozhong Rd.-Yunshan Rd.	West	5	LT	Variable	TH	TH	TH + RT
5	Xizangbei Rd.-Haining Rd.	North	3	LT	Variable	TH	RT

Note: the approach lanes are numbered from left to right. LT, TH, and RT refer to the left-turn, through movement, and right-turn, respectively.
