To provide a processing method and the like of lateral pressure measurement data capable of reducing an error of lateral pressure due to wheel load with a simple device configuration.SOLUTION: In a processing method of lateral pressure measurement data, wheel load measurement data and lateral pressure measurement data are acquired by a wheel load lateral pressure measurement device for measuring wheel load and lateral pressure acting between a wheel 110 and a rail R of a railway vehicle 1, a contact position lower limit value which is a lower limit value of a displacement amount in the sleeper direction from a prescribed reference position of a contact position between the wheel and the rail is obtained based on the wheel load measurement data, the lateral pressure measurement data, and data relating to a wheel shape previously acquired, and the lateral pressure measurement data is corrected by using the contact position lower limit value and the wheel load measurement data.SELECTED DRAWING: Figure 1
