Abstract
A traffic safety control method is provided. The method includes determining whether there is an intersection in front of a vehicle. When there is the intersection in front of the vehicle, a driving direction of the vehicle at the intersection is predicted according to a plurality of lane positions of the vehicle that are continuously obtained. A message is transmitted once the predicted driving direction is determined to be conflicting with a traffic rule of the intersection.
Claims12
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.

The traffic safety control method according to claim wherein the method further comprises:
- obtaining a latest lane position of the vehicle when the distance of the vehicle from the intersection is less than the second preset distance;
- transmitting a warning when the predicted driving direction is the left turn, and the latest lane position is a middle lane or an outermost lane;
- and
- transmitting the warning when the predicted driving direction is the right turn, and the latest lane position is a middle lane or an innermost lane.

A vehicle-mounted device comprising:
- a storage device;
- at least one processor;
- and
- the storage device storing one or more programs, which when executed by the at least one processor, cause the at least one processor to:
- determine 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;
- predict 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
- transmit a message when the predicted driving direction is in conflict with a traffic rule of the intersection.
