To provide an abnormality detection method that detects an abnormality occurring in an infrastructure sensor device and upgrades the reliability of information obtained from the infrastructure sensor device.SOLUTION: An abnormality detection method of an infrastructure sensor device in accordance with the present invention detects a moving entity that passes within a sensing range. The abnormality detection method includes steps of: calculating (S1) moving entity information which includes at least position information and moving speed information on a moving entity on the basis of information on the moving entity detected by the infrastructure sensor device; calculating (S2) probe data which includes at least the position information and moving speed information on the moving entity on the basis of self-position information on the moving entity received using a wireless communication function of the moving entity; and performing (S3) abnormality decision processing of, when the moving entity information is inconsistent with the probe data, deciding that an abnormality has occurred in the infrastructure sensor device.SELECTED DRAWING: Figure 5

    【課題】インフラセンサ装置に生じた異常を検出してインフラセンサ装置から得られる情報の信頼性を向上させる異常検出方法を提供する。【解決手段】本発明のインフラセンサ装置の異常検出方法は、センシング範囲内を通過する移動体を検出するインフラセンサ装置の異常検出方法であって、インフラセンサ装置が検出した移動体の情報に基づき移動体の位置情報及び移動速度情報を少なくとも含む移動体情報を算出し(S1)、移動体が有する無線通信機能を用いて受信した移動体の自己位置情報に基づき前記移動体の位置情報及び移動速度情報を少なくとも含むプローブデータを算出し(S2)、移動体情報とプローブデータとが不一致であった場合にインフラセンサ装置に異常が発生していると判断する異常判断処理(S3)を行う。【選択図】図5
