Traffic lights ensure the orderly and smooth traffic flow of the whole road network, while the traditional traffic lights control mode often can not achieve the purpose of dynamic adjustment of traffic lights according to the real-time traffic flow of the intersection, resulting in the intersection congestion. Therefore, this paper introduces the linear regression algorithm to fit on the basis of the adaptive timing algorithm Webster, and obtains an improved algorithm with higher efficiency than the traditional method. The improved algorithm obtained is obviously superior to the traditional traffic light timing algorithm in the case of different traffic flows.
