The invention relates to the technical field of interchange design, and discloses an interchange variable-speed lane road width calculation method, which comprises the following steps of: performing characteristic paragraph division on ramps in a variable-speed section range of an interchange variable-speed lane to generate a ramp sideline sequence; calculating a speed change section pile number, a master-slave route direction, an additional orientation and an additional orientation according to the route design parameters; calculating intersection point coordinates of a main line stake mark normal and a ramp sideline on the additional orientation side according to the speed change section stake mark, the master-slave route direction, the additional orientation and the attached orientation; and calculating the road width of the additional azimuth side according to the coordinates of the intersection point of the main line stake mark normal and the ramp sideline of the additional azimuth side. According to the method, the characteristic paragraph of the interchange connecting part is divided, and the characteristic point stake number calculation, the main and auxiliary route direction calculation, the additional direction calculation and the additional direction calculation are performed according to the route design parameters, so that the width calculation of any position of the variable-speed lane is realized, and the road width calculation efficiency and accuracy are improved.
