The invention discloses a road congestion event detection and early warning system which is capable of rapidly realizing judgment and early warning of road congestion and gives an alarm the first time. The invention further provides a road congestion event detection method. When a car goes by, the congestion condition of a section area is determined by obtaining signals generated by two induction devices which are buried at an interval in front and at the back of a road section; and by adopting the method, the detection efficiency of a congestion event is improved so as to obtain a more rapid and accurate detection result. The system and the method have the advantages that 1) the totally-new road congestion event early warning method is created; 2) early warning is performed uninterruptedly, and the timeliness and the continuity of early warning are improved; and 3) the detection precision is improved, and the discovering time of the congestion event is earlier.
