A method and apparatus for outputting information is disclosed in embodiment of that present application. One embodiment of the method includes acquiring trajectory information of a first condition ofa predetermined number of days and trajectory information of a second condition of a predetermined number of days of at least one path; Generating a second conditional trajectory characteristic of the path and a first conditional trajectory characteristic of the path based on trajectory information of a second condition of a predetermined number of days of the path and trajectory information of afirst condition of a predetermined number of days of the path, respectively, for the path in at least one path; Determining a similarity between a second conditional trajectory feature of the path and a first conditional trajectory feature of the path for a path in at least one path; Selecting a first predetermined number of paths based on similarity, and outputting a path name of the selected path. This embodiment is capable of predicting a traffic congestion section of the first condition due to stagnant water, thereby optimizing the navigation route.
