The invention discloses an automobile running speed optimization method considering the influence of a waiting queue at an intersection. The method comprises the steps of firstly setting a road withina certain distance from an intersection stop line as a control region, and obtaining the number of to-be-driven automobiles through a geomagnetic coil; then, calculating the acceleration/decelerationof the automobiles in the waiting queue by utilizing an intelligent driver automobile following model, calculating the length and speed change track of the waiting queue based on an automobile kinematics model, and estimating the passing time of the waiting queue; and finally, establishing an automobile model, designing an automobile speed optimization problem containing the automobile and traffic constraints, and calculating the economical passing automobile speed of the automobile by adopting a dynamic programming algorithm. By utilizing the existing mature technical conditions, and under the condition that the intelligent network connection automobile technology is not popularized on a large scale, the safe, energy-saving and efficient passing speed optimization of automobiles at urbancongestion intersections is achieved, and an accurate and reliable speed basis is provided for the technologies of economical driving, green passing, efficient passing at the intersections and the like of the automobiles.
