The invention provides a method and system for recognizing an abnormal segment of a traffic road, and the method comprises the steps: obtaining the traffic data of all floating cars, wherein the traffic data comprises series number of the floating cars, time point information, geographical location information, and vehicle speed information; calculating and obtaining vehicle speed change information and direction change information, corresponding to a time axis, of all floating cars according to the time point information, geographical location information, and vehicle speed information; judging and obtaining a floating car which changes a lane after speed reduction and then increases speed according to the vehicle speed change information and direction change information; extracting all corresponding traffic data of the floating car in a process of lane change after speed reduction and speed increase, and obtaining a traffic data set; positioning and obtaining a set of road segments where the floating cars are located according to the geographical location information in the traffic data set. The method achieves the recognition of the abnormal segment of the traffic road, and provides convenient and reliable service basis for the safe maintenance of the traffic road.
