Traffic network state prediction method and system

The invention discloses a traffic network state prediction method and system, and relates to the technical field of computer application, and the method comprises the steps: obtaining a plurality of traffic routes according to a preset traffic intersection; traversing to obtain vehicle state information and pedestrian state information; according to the vehicle state information, predicting a vehicle congestion state of a preset traffic intersection in a preset time, and generating a vehicle density prediction result; according to the pedestrian state information, predicting a pedestrian flow congestion state of a preset traffic intersection in a preset time, and generating a pedestrian flow density prediction result; predicting and generating a vehicle passing duration prediction result; judging whether the vehicle passing time length prediction result meets preset time length or not; if yes, traffic network state early warning information is generated and sent to a traffic control end.
