ABNORMALITY DETECTION METHOD OF INFRASTRUCTURE SENSOR APPARATUS, INFRASTRUCTURE SENSOR APPARATUS, INFRASTRUCTURE SENSOR SYSTEM, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING AN ABNORMALITY DETECTION PROGRAM

摘要

An abnormality detection method of an infrastructure sensor apparatus according to the present disclosure is an abnormality detection method of an infrastructure sensor apparatus configured to detect a mobile body that passes within a sensing range, the abnormality detection method including: calculating mobile body information at least including positional information and moving speed information on the mobile body based on information on the mobile body detected by the infrastructure sensor apparatus; calculating probe data at least including positional information and moving speed information on the mobile body based on self positional information of the mobile body received using a radio communication function included in the mobile body; and performing abnormality determination processing in which it is determined that there is an abnormality in the infrastructure sensor apparatus when the mobile body information does not match the probe data.
