A traffic lane line fitting method and system, the traffic lane line fitting method comprising: obtaining map information for a current position of a vehicle (S110), the map information comprising a number of traffic lanes, a road width and line point information of traffic lane lines on both sides of the vehicle; determining, from among the traffic lane lines on both sides of the vehicle, a traffic lane line on one side, consistent with the direction indicated by at least one of the following, to be a traffic lane line offset reference used for traffic lane line fitting (S 120): a lane change direction side, a driving coordinate system reference side, a constant road width side, and a traffic lane continuous side; offsetting and generating a plurality of traffic lane lines of the vehicle on the basis of the traffic lane line offset reference (S 130); performing curve fitting on a set of line points on the generated plurality of traffic lane lines so as to obtain a corresponding traffic lane line equation (S 140). The traffic lane line fitting method solves the problem that extracted traffic lane lines are numerous and relatively complex.
