1. A traffic safety control method applied to a vehicle-mounted device, the method comprising:
determining whether there is an intersection in front of a vehicle, comprising: capturing an image using a camera that is installed on the vehicle; identifying whether the captured image comprises an image of a traffic light using an image recognition algorithm; and determining there is the intersection in front of the vehicle when the captured image comprises the traffic light;
predicting a driving direction of the vehicle at the intersection according to a driving path formed by a plurality of lane positions of the vehicle that are continuously obtained when there is the intersection in front of the vehicle, wherein the plurality of lane positions is obtained by: beginning from the vehicle being at a first preset distance from the intersection, identifying a lane position of the vehicle each time when the vehicle travels for a second preset distance, until the vehicle is at a distance from the intersection less than the second preset distance; and
transmitting a message when the predicted driving direction is in conflict with a traffic rule of the intersection.
