The invention provides a method and device for the intelligent sensing of a traffic situation, and the method comprises the steps: a vehicle obtains the position and speed of the vehicle through a vehicle-mounted positioning apparatus; the information of other surrounding vehicles and the vehicle information transmitted by the surrounding vehicles are obtained in a mode of short-distance wireless communication, the information of the vehicle is transmitted periodically, and other vehicle information is also transmitted periodically; and the transmitting and forwarding of data and frequency are controlled according to the vehicle speed, the distance and direction of a forwarding vehicle, and the timeliness of information. The traffic situation of a current point can be judged according to the obtained vehicle speed; the front traffic situation can be judged according to the obtained speed of a front vehicle, thereby achieving the intelligent sensing of the front traffic situation at the moment. When a traffic jam happens, the position of a vehicle at the slowest speed is searched through the received front vehicle information, and the jammed point can be determined. The reason of the traffic jam can be obtained through a short message or code which describes the traffic situation and is sent by the owner of the vehicle, thereby achieving the intelligent sensing of the traffic situation.
