Trunk line intersection control method based on fuzzy control

The invention relates to a trunk line intersection control method based on fuzzy control. The trunk line intersection control method comprises the steps that S1, timing basic parameters of a trunk line intersection signal phase are calculated; s2, calculating timing advance parameters in saturated and unsaturated states of the intersection; s3, dividing the trunk line between the intersections into a detection road section, a first sub-road section and a second sub-road section; s4, respectively determining an exit lane unblocked index, a queuing dissipation index and a downstream road sectionunblocked index of the intersection phase; s5, calculating to obtain a trunk line coordination control index; s6, determining a trunk line upstream congestion index of the intersection phase; s7, designing a trunk line coordination fuzzy controller to output green light predicted display time; s8, determining a trunk line coordination constraint index; and S9, calculating the green light displaytime of the intersection p
