<P>PROBLEM TO BE SOLVED: To measure a road surface state of a level difference and irregularity with high accuracy. <P>SOLUTION: A road surface state measurement method includes processes of: recording an output of a load sensor 111 at every prescribed sampling interval by having a vehicle travel while loading it with a sensing device 112 in which the load sensor 111 is loaded with a weight 113 of prescribed weight; recording position information of a recording position corresponding to the output; and calculating a change of a value of an impact load relative to a static load to display it in association with the position information, where the output of the load sensor 111 in a state that only a load by gravity of the weight 113 is applied is noticed as the static load, and the output of the load sensor 111 while the vehicle travels is noticed as the impact load. <P>COPYRIGHT: (C)2012,JPO&INPIT |
