The invention discloses a dynamic traffic information release method and a dynamic traffic information release system. The method comprises the following steps: receiving GPS dynamic real-time data and/or a picture taken by a user uploaded by a vehicle terminal; fusing the GPS dynamic real-time data and the picture taken by the user to get corresponding dynamic traffic information data; and releasing the dynamic traffic information data through the vehicle terminal. Real-time traffic condition information of an area in the running direction can be provided for a vehicle owner according to the running direction and position information of the vehicle; the vehicle owner can collect and upload traffic condition information, and a dynamic data acquisition function is achieved; the method and the system support half-screen/full-screen picture display, and the information is truer and more accurate; and real-time traffic information is broadcasted by voice and scroll-displayed, and irrelevant traffic information is screened out to bring convenience to the travel of the vehicle owner. Based on the mature 4G network, all terminals can upload collected data and release/get information, and an 'Internet of vehicles' is truly realized.
