The invention discloses a road traffic event analysis method, system and device and a medium, and relates to the field of road traffic recognition. The method comprises the following steps: decoding and coding a current monitoring video to obtain a target video picture; calibrating the target video picture to obtain a calibrated video picture; performing preliminary analysis on the calibrated video picture to obtain a preliminary analysis result; determining state change data according to the preliminary analysis result; counting traffic flow to determine high and flat peak time periods of a road traffic site; performing preliminary detection on each frame scene according to detection parameters corresponding to predetermined high and flat peak time periods to obtain a preliminary detection result; a congestion event in the preliminary detection result is eliminated; tracking the target, determining the motion state characteristics, obtaining a final detection result, and reporting the final detection result; the scale of the traffic accident event triggered in the detection result and the statistical result are used for adjusting the detection parameters corresponding to the high and flat peak time periods. According to the invention, the detection accuracy of the road traffic event can be improved.
