The invention provides a method capable of estimating traffic states of a highway, and aims to solve the problems that conventional highway traffic loads are increased day by day and traffic capacity and service level of a road are remarkably reduced. According to a basic idea, flow and speed data are detected by a detector, three parameters of traffic around the detector are estimated firstly, weighting estimation of different zones are obtained according to the position relation of a display unit and a detector, weighting is performed according to the traffic parameters of the zones, traffic states of the display unit are obtained, and finally, the traffic states are graded through a threshold. The efficient highway traffic state identification method is provided, and limited road network space-time resources are exerted to the greatest extent.
