The invention relates to a road traffic vehicle speed induction method. The method is mainly and technically characterized in that an intersection information releasing module releases intersection information in real time; an intersection information obtaining module receives the intersection information in real time and transmits the intersection information to a core processing module; a vehicle positioning module obtains the speed and the position of a vehicle in real time and transmits the speed and the position to the core processing module; according to the intersection information and the vehicle position and the vehicle speed of the vehicle, the core processing module calculates the speed of the vehicle passing an intersection in a green light period, and the speed of the vehicle is induced. The method is reasonable in design, it is guaranteed that the vehicle reaches the intersection in the traffic signal green light period and quickly passes the intersection, it is avoided that the vehicle parks at the intersection during a red light period, average speed of the vehicle passing the intersection is greatly increased, more vehicles can pass in the limited green light time, and the go-through efficiency of the whole traffic intersection is effectively improved.

The invention discloses a vehicle identification method. The method comprises the steps of acquiring a to-be-identified vehicle image of a to-be-identified road section; extracting concave points andconvex points of the to-be-identified vehicle image, and constructing a concave point model and a convex point model of the to-be-identified vehicle image according to the concave points and the convex points; and based on the concave point model and the convex point model, pairing the to-be-identified vehicle image with a vehicle image database to obtain a vehicle identification result of the to-be-identified vehicle image, and obtaining a traffic flow condition of the to-be-identified road section. The invention further discloses a vehicle recognition device, the problem that in the prior art, the feature extraction difficulty of the road traffic vehicle is large can be effectively solved, the vehicle image features can be stably extracted, and the high recognition degree is achieved.
