A road segment dynamic fee collecting control method guaranteeing lane quality

The invention provides a road segment dynamic fee collecting control method guaranteeing lane quality. The method comprises the steps of: acquiring a road traffic saturation degree of a fee collectingroad segment in real time by using a traffic flow detection apparatus; when the detected road traffic saturation degree is less than a set threshold, collecting a road using fee x0, wherein x0 changes dynamically according to a road using fee regulation factor beta 0; when the detected road traffic saturation degree is greater than the set threshold, determining that the lane quality of the roadsegment reduces and adding a road quality regulation fee x1 on the basis of collecting the road using fee of the road segment, wherein the regulation fee is determined by the road traffic saturation degree which is detected in real time and a road quality fee collecting regulation factor beta 1; defining a fee collecting price update state period as T. The quality fee collecting price of a road segment dynamically changes
