The present invention provides a method for measuring a road slope using the driving date of a vehicle that acquires road alignment information by driving, on a road, the vehicle including a vehicle position information sensor and vehicle posture information sensor, and can measure correct information on the road. The method for measuring a road slope using the driving date of a vehicle comprises the steps of: (A) acquiring vehicle position information and vehicle posture information via the vehicle position information sensor and the vehicle posture information sensor installed on a moving device driving on a road (referred to as′vehicle′hereinafter); (B) measuring the driving track of the vehicle using the acquired vehicle position information and the vehicle posture information; (C) calculating a vertical slope and a cross slope using the measured driving tracks in both directions of the vehicle; (D) removing outliers using a smoothing method including a moving average method in the calculated vertical slope and cross slope; (E) calculating, at predetermined intervals, the measured values of the vertical slopes and the cross slopes having the outliers removed, and choosing the average values of the values included in each interval as representative values; (F) separating the chosen representative values into curves having changing slopes and unchanged slopes; and (G) measuring the geometric structure of the road by correcting errors using the critical values of difference in the heights of both straight lines and finally separating straight lines and curves if the slopes and the curves are separated. |
