PURPOSE:To enable the accurate milage measurement, by receiving signals containing data on a distance from a point located on a running route and by correcting a measured distance value on the basis thereof. CONSTITUTION:When a bus 1 running on a predetermined route approaches a bus stop, weak transmission signals containing data on distance, which are outputted by a transmitter 21 of a fixed station 16 provided at the stop, are received by a receiver 22. Based on these received signals, a measured distance value in accordance with the transmission of a force of rotation of an axle is corrected by a speed detector 7 and a processing device 10. Accordingly, an accurate measurement of distance can be conducted. |
