Abstract

An aspect relates to providing a track-side device anomaly detection technique for detecting an anomaly related to a track-side device and determining an appropriate response action to mitigate an impact of a communication failure resulting from the track-side device anomaly. The track-side device anomaly detection method includes generating a set of error record data indicating presence or absence of a transmission error between a set of railcars and a set of track-side devices, generating a set of error count data indicating a number of detected transmission errors, detecting an anomaly related to a first track-side device based on the set of error count data, determining a priority level of the first set of track-side data configured to be transmitted by the first track-side device, and determining a response action related to the first track-side device based on the priority level of the first set of track-side data.
