Vehicle detection system

A method of detecting vehicles, the method comprising:

• capturing an image of a vehicle using a camera;
• using a receiver to listen for a data transmission from the vehicle;
• determining whether said data transmission has been received from the vehicle;
• if said data transmission is received from the vehicle, using said image to train a trained model further to detect and/or classify vehicles, and
• if no data transmission is received from the vehicle, using the image and the trained model to detect and/or classify the vehicle in the image.

A non-transitory computer-readable medium having stored thereon program instructions that, upon execution by a computing device, cause the computing device to:

• capture an image of a vehicle using a camera;
• listen for a data transmission from the vehicle;
• determine whether said data transmission has been received from the vehicle;
• if said data transmission is received from the vehicle, use said image to train a trained model further to detect and/or classify vehicles, and
• if no data transmission is received from the vehicle, use the image and the trained model to detect and/or classify the vehicle in the image.
