The invention provides a traffic road condition prediction method and system based on Internet of Vehicles big data, and relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining historical track data of a to-be-detected region in a preset time period before a current moment; respectively acquiring first trajectory data and second trajectory data of traffic road conditions in the to-be-detected area; processing the first trajectory data and the second trajectory data on the basis of a three-dimensional vector to obtain flow information of all vehicle trajectories, and performing grey correlation analysis to obtain a correlation value between each piece of flow information and the historical trajectory data; and processing to obtain traffic road condition prediction information. The method has the beneficial effects that the accuracy of road condition prediction is improved, traffic congestion is effectively reduced, travelers are helped to select proper traffic routes to travel, time is saved, the traffic efficiency of existing roads is improved, the road congestion condition is improved, the urban traffic congestion phenomenon is relieved, and the comprehensive management level of urban road traffic is improved.
