<P>PROBLEM TO BE SOLVED: To provide a tread frame for achieving the unitary management of vehicle specification information and axle weight information without deteriorating the detecting accuracy of the pressurization or axle weight of a vehicle. <P>SOLUTION: Disclosed is a tread 20 equipped with a tread body 21 installed in the width direction of a path for passage processing of a pay facility for vehicle, and internally formed with a plurality of spaces 32 extended in the width direction in the traveling direction of a vehicle and a pair of contact bodies 34 installed so as to be vertically faced to each other on an inner surface 33 of the space 32, and configured to detect the pressurization of the vehicle according to the contact of the pair of contact bodies 34. The tread 20 includes: a pressure sensor 40 configured to detect the internal pressure of at least one space 32 among the plurality of spaces 32; and an axle weight detection part 50 configured to calculate the axle weight of the vehicle which has passed the path on the basis of the detection result of the pressure sensor 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
