VISSIM simulation settings.

Parameter	Value
Length of the connecting section of the intersection	470–490 meters
Lane width	3.5 meters
Number of lanes	4 (two way)
Turning ratio	3 : 7 (turn left: straight)
Speed distribution	[20 km/h, 60 km/h]
Car type distribution	3 : 97 (bus : car)
Signal control	Stage1-north and south straight. Stage2-north and south straight left. Stage3-east and west straight. Stage4-east and west left.
Stage time	Stage1–40 s. Stage2–20 s. Stage3–40 s. Stage4–20 s.
Input flow	Stage1-1000 v/h. Stage2–500 s. Stage3–1000 s. Stage4–500 s. Multiply the stage flow by a random number x every 3600 s. 0.5 < x < 2
