Table 2

Summary of scenarios, traffic demand volume, and outputs.

Type of turn	Number of lanes	Through traffic volume (Veh/h)	Right-turn traffic volume (Veh/h)	Left-turn traffic volume (Veh/h)	Outputs
Right-turn	Single lane	400	100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800	150	Delay and volume to capacity (V/C)
	Dual lane	400	200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, 1300, 1350, 1400, 1450	150
Left-turn	Single lane	400	150	50, 100, 150, 200, 250, 300, 350, 400
