The invention relates to an expressway induction lamp system and method based on audio event detection. The expressway induction lamp system comprises induction lamps installed on the two sides of a road, an edge computing server and a server platform of a control center. The induction lamps, the induction lamp system and the edge computing server communicate in a wireless ad hoc network mode for transmitting audio data collected by microphones of the induction lamps. The edge computing server communicates with the server platform in a 5G communication mode of a mobile operator, the detected traffic event and state are reported through a 5G communication network of the mobile operator, and the audio algorithm sample library is updated. According to the technical scheme, besides the functions of synchronous flickering and wake tracking, the microphone is arranged in each induction lamp, and on-site audios are collected in real time; when a traffic accident happens to a vehicle, vehicle collision sound is generated and analyzed through an edge computing server audio AI algorithm, so that the traffic accident is detected, and accident position information is uploaded to the control center.
