Abstract: In a travel status recording apparatus, a data acquisition unit acquires first travel status data and second travel status data indicating a travel status in relation to a vehicle. An event detection unit detects a predetermined event that occurs in relation to the vehicle based on the first travel status data acquired. In response to the predetermined event being detected, a data analysis unit analyzes the second travel status data using artificial intelligence. A recording control unit records, in a storage unit, an analysis result of the second travel status data in association with event detection information in relation to the predetermined event.
