An amount of wear of a railroad vehicle wheel flange may be measured directly and online during travel along a curved section of track. A laser rangefinder 3 is installed on an outer track side in a rounded curve section of a railroad track. When a railroad vehicle travels through the rounded curve section, the laser rangefinder 3 measures a distance to a front rim surface lrf of a wheel Isfo on an outer track side of a wheelset Sf in a forward direction of travel of a bogie B forming a vehicle. The amount of wheel flange wear is obtained by comparing this measured distance with a previous measurement of the measured distance. This makes it possible to manage, during travel, the amount of wheel flange wear when traveling in a curved section, thus making it possible to quickly find wheels having flange wear that has exceeded a control range, so as to ensure safety when a railroad vehicle is traveling through a curved section.
