A trail analysis method of movable object includes acquiring first stay event data indicating a first location, a first arrival time of a first movable object to the first location and a first staying time, and second stay event data indicating a second location, a second arrival time of a second movable object to the second location and a second staying time, evaluating coincidence between the first and second locations based on the first and second stay event data, evaluating whether a first time zone specified by the first arrival time and the first staying time and a second time zone specified by the second arrival time and the second staying time overlap, from the first and second stay event data, and evaluating contact between the first and second movable objects using location and staying time evaluation results.
