The invention discloses a road congestion degree identification method and an early warning system under a discrete time system. The method comprises the following steps: carrying out two-dimensional time vector division on any time period according to traffic flow characteristics of different time periods; calculating to obtain predicted vehicle arrival rates and predicted vehicle retention probability distribution laws under different two-dimensional time vectors; designing a quantitative standard to predict road congestion degree indexes under different time vectors; and finally, setting a road congestion degree early warning threshold value and a road congestion degree grade according to the road congestion degree index. The system comprises a traffic condition early warning data receiving module, a signal processing module, a signal lamp indication module, a buzzer early warning module, a computer storage module and a transmitting antenna module. The road congestion condition is predicted according to the real-time traffic data of different road sections, the traffic congestion condition is improved to a great extent, the judgment and attendance efficiency of traffic control personnel is improved, the prediction energy efficiency of the traffic road sections is reduced, and the traffic pressure is relieved.
