The invention discloses a traffic flow model simulation method and system and an abnormal traffic event prediction method, and relates to the technical field of traffic management.The method comprises the steps that firstly, a traffic flow model is constructed based on the cellular automaton theory; initializing the traffic flow model, and setting an initial moment t to be equal to 1 and a simulation termination moment to be T; traversing the vehicle information array by using a traffic flow model, and determining the attribute of the current cellular occupying vehicle; according to the attribute of the current cellular occupying vehicle, based on the position of the current cellular in the road network, vehicle state updating is carried out; tlt is judged; judging whether T is true or not, if yes, enabling t to be equal to t + 1, and returning to the model traversal step; and if not, the simulation is ended. According to the traffic flow model simulation method provided by the invention, the evolution law of the traffic flow under typical traffic events can be simulated, so that traffic abnormal events are prevented and controlled, and the influence caused by traffic accidents is reduced.
