The invention discloses an intersection signal lamp timing sensing method based on a vehicle track and electronic equipment. The method comprises the steps that S1, an intersection is designated, track information of vehicles passing through the intersection in the direction is obtained, timing estimation parameters of all the vehicles are extracted from the track information, and the timing estimation parameters comprise the braking deceleration moment t1, the parking moment t2, the parking duration T3 and the passing duration T4; s2, filtering the vehicle track information obtained in the step S1, and removing the track information of vehicles which are not parked at the intersection; s3, calculating a vehicle arrival rate d in the direction of the intersection and a vehicle departure rate a in the direction of the intersection according to the timing estimation parameters; selecting to meet the condition of egt; and S4, performing linear regression analysis according to discrete values of the vehicle tracks of the intersection in the direction to obtain the red light timing Tred of the intersection in the direction.
