PROBLEM TO BE SOLVED: To provide an axle number detector, an axle number detection method and a program, capable of accurately detecting an axle number of a vehicle even when a vehicle enters a step board obliquely.SOLUTION: An axle number detector (1) comprises: a step board (20) which is installed in a lane width direction, and outputs a tire detection signal according to treading of tires of a vehicle which travels; a detection time information acquisition part (300) for acquiring detection time information which indicates a time when the tire detection signal is output; an axle determination part (301) for determining whether or not, two tire detection signals are tire detection signals caused by treading of two tires attached to a same axle of the vehicle, based on the detection time information; and an axle number identification part (302) for identifying the number of pairs of the two tire detection signals determined to be tire detection signals caused by treading of two tires attached to the same axle, as an axle number of the vehicle.SELECTED DRAWING: Figure 2
【課題】車両が踏板に対して斜めに進入した場合であっても、高い精度で車両の車軸数を検知することができる車軸数検知装置、車軸数検知方法及びプログラムを提供する。【解決手段】車軸数検知装置(1)は、車線幅方向に設置され、走行する車両のタイヤの踏み付けに応じてタイヤ検知信号を出力する踏板(20)と、前記タイヤ検知信号が出力された時刻を示す検知時刻情報を取得する検知時刻情報取得部(300)と、前記検知時刻情報に基づいて、二つの前記タイヤ検知信号が、前記車両の同一の車軸に取り付けられた二つのタイヤの踏み付けによるタイヤ検知信号であるか否かを判定する車軸判定部(301)と、同一の車軸に取り付けられた二つのタイヤの踏み付けによるタイヤ検知信号である判定された二つの前記タイヤ検知信号の対の数を、前記車両の車軸数として特定する車軸数特定部(302)と、を備える。【選択図】図2
