The invention discloses a method of utilizing GPS trip survey data to identify trips and activities. The particular identifying method comprises four stages, namely a first stage, a second stage, a third stage and a fourth stage, wherein the first stage is used for dividing the state, the second stage is used for identifying the activities, the third stage is used for identifying the trips, and the fourth stage is used for identifying the short-time activities; the first stage comprises four steps, namely Step 1, converting data points into data segments, Step 2, judging the stage of the data segments, Step 3, combining the adjacent data segments under the same state, and Step 4, adjusting the state of the state segments. The identifying method disclosed by the invention can be used for identifying the trip and activity information based on the GPS trip survey data, so as to identify all the trips, activities and short-time activities with the activity time within seven minutes, and achieve high identification accuracy.
