To identify a sign of failure of a vehicle detector or an axle counter.SOLUTION: A roadside device provided in a lane of a toll gage according to an embodiment includes: a plurality of detection means that detect passing vehicles; and a lane server that manages the number of parked vehicles staying in the lane based on detection results of the detection means. The lane server includes: a detection control unit that determines whether or not detection information about a vehicle is acquired from each of the plurality of detection means when the vehicle passes through the lane of the toll gate, and updates a plurality of cumulative detection counts indicating the number of times detection information has been acquired from each of the plurality of detection means; a failure determination unit that calculates a difference for each of the plurality of cumulative detection counts and determines whether the calculated difference exceeds a predetermined threshold value; and a transmission unit that transmits failure sign information when it is determined that the predetermined threshold value is exceeded.SELECTED DRAWING: Figure 1
【課題】車両検知器または軸数計の故障の予兆を特定すること。【解決手段】実施形態に係る道路の料金所のレーンに設けられる路側装置において、通過車両を検知する複数の検知手段と、検知手段の検知結果に基づいてレーンに滞在する在車数の管理を行う車線サーバと、を備え、車線サーバは、車両が料金所のレーンを通行する際、複数の検知手段のそれぞれから車両についての検知情報を取得したかどうかを判定し、複数の検知手段それぞれで検知情報を取得した回数を示す複数の累計検知回数を更新する検知制御部と、複数の累計検知回数それぞれに対する差を算出し、算出された差が所定の閾値を超えるかどうかを判定する故障判定部と、所定の閾値を超えたと判定した場合、故障予兆情報を送信する送信部と、を備える。【選択図】 図1
