Besides, it can count road vehicle flow. And the system can effectively monitor vehicle speeds, able to operate day and night and widely applied.

The invention discloses a road traffic vehicle speed-measuring instrument, which comprises a base arranged on a road support and a speed-measuring instrument body which is in fit connection with the base, and is characterized in that the top surface of the speed-measuring instrument body is provided with a strip block, and the left end face and the right end face of the strip block are symmetrically provided with two grooves. According to the road traffic vehicle speed-measuring instrument, the speed-measuring instrument body is firmly locked and safely and stably powered on, during mounting,the speed-measuring instrument body is first locked and then powered on, and during detaching, the speed-measuring instrument body is first powered off and then unlocked, the whole device is convenient and fast to operate, the unlocking of the speed-measuring instrument body can be realized by controlling a first motor to work for reverse rotation, so that the speed-measuring instrument body mounting and detaching efficiency is greatly improved, and the electric shock accident during speed-measuring instrument body mounting and detaching can be effectively avoided.

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 relates to a metal braking vane and a use method thereof. The metal braking vane is used for a road traffic vehicle and comprises a vane body. The vane body is provided with grooves. Braking strips are arranged in the grooves. Metal teeth are arranged at the upper portions of the braking strips at intervals and protrude out of the surface of the vane body. The vane body is fixed to a braking vane fixing frame through bolts or clamping buckles and clamping grooves to form a braking system arranged at the bottom of the vehicle. The braking vane is operated to ascend and descend through a hand brake rod. The braking effect is achieved through friction resistance between the metal teeth on the braking vane and the road surface.

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.
