The embodiment of the invention provides an intersection traffic edge server. The intersection traffic edge server comprises an underlying hardware service unit, a self-adaptive basic service unit and a self-adaptive scheme generation unit, the self-adaptive basic service unit is used for obtaining an intersection signal control optimization index under each selectable phase sequence according to the flow direction evaluation index of the intersection; the self-adaptive scheme generation unit is used for obtaining a credit control timing scheme according to the optimization index, determining the scheme saturation after the credit control timing scheme is operated, and selecting a target phase sequence and the corresponding credit control timing scheme according to the scheme saturation; and the underlying hardware service unit is used for providing local computing power by the traffic edge server, acquiring intersection detector data and sending a signal control timing scheme to an intersection signal machine. According to the technical scheme provided by the embodiment of the invention, the period, the green light time and the phase sequence of the signal control timing scheme of the intersection are optimized, and the fluency of the intersection is improved.
