The invention discloses a determining method for eliminating a stop line position in an intersection dilemma zone. The determining method comprises the following steps that: firstly, through a manualcounting method, collecting traffic data; then, guaranteeing that vehicles in an intersection can be effectively emptied in intersection green light interval time so as to determine a first minimum position of a distance from an upstream stop line to the intersection; then, guaranteeing that the dilemma zone can be eliminated so as to determine a second minimum position; and finally, fully utilizing the land area of the intersection, taking a minimum value in a feasible value range so as to improve the graphic symbol utilization efficiency of the intersection and improve traffic capacity. By use of the method, a driver can be prevented from generating dilemma confusion mentalities in the intersection green light interval time, the regulation violation rates of vehicles in the intersectionare lowered, the conflict of the intersection is reduced, and driving safety is guaranteed.
