Abnormal condition determination method and forward matching formula generation method

The invention provides an abnormal condition determination method and a forward matching type generation method, and relates to the technical field of traffic safety. According to the abnormal condition determination method, audio information corresponding to a to-be-detected service is acquired, and text information corresponding to the audio information is acquired. Then, according to the forward matching formula and the text information, correlation degree information of the text information and the abnormal condition is determined, the forward matching formula and the abnormal condition have a forward relation, and the correlation degree information represents a correlation degree value of the text information and the abnormal condition; and when the correlation degree information is greater than a correlation degree threshold, the condition that the to-be-detected service has an abnormal condition is determined. Therefore, whether the vehicle corresponding to the to-be-detected service has traffic accide
