ROAD SURFACE EVALUATION SYSTEM AND EVALUATION METHOD
To provide a road surface evaluation system and evaluation method that can evaluate a road surface accurately and easily.SOLUTION: A road surface evaluation system includes: a vehicle speed sensor (5); a device that acquires information on the current position of a vehicle (1); an outside temperature measuring device (9); and a control device (10). A road surface noise measuring device (3) measures the road surface noise on the tires of the vehicle (1). The system corrects a sound pressure level according to the outside temperature and vehicle speed; calculates a sound pressure level difference between the corrected sound pressure level of the road surface noise and the sound pressure level of a reference road surface; determines the characteristics of the calculated sound pressure level difference and the position of the road surface; creates image data that can evaluate the road surface from the characteristics of the calculated sound pressure level difference and the position of the road surface; and performs a road surface evaluation based on the created image data.SELECTED DRAWING: Figure 2
