Intelligent control method and system for traffic lights

The invention discloses an intelligent control method for a traffic signal lamp, and the method comprises the steps: obtaining a first intersection, and obtaining a first preset time period; obtaining first traffic flow information of the first road and second traffic flow information of the second road; obtaining a first fitting curve; obtaining a first slope set of the first fitting curve along with the time axis; training the first slope set to obtain a first signal lamp control model; obtaining third traffic flow information and fourth traffic flow information at the first time, and inputting the information into a first signal lamp control model to obtain a first signal lamp control scheme; and controlling the first signal lamp according to the first signal lamp control scheme. The technical problems that due to the fact that traffic scenes are complex and changeable, emergencies occur frequently, a traffic signal lamp control scheme is poor in flexibility, a scientific and humanized control method is la
