A light-diffusing LED lens adopting an asymmetric free-form surface expression is provided to improve the uniformity ratio of illumination of the target region by controlling the light from the LED serving as a light source. The light-diffusing LED lens adopting an asymmetric free-form surface expression exhibits light control and illumination efficiency suitable for highway environment conditions and characteristics of traffic lanes. Both the light incident surface and the light emitting surface of the light-diffusing LED lens are formed into an aspherical surface, in which an asymmetrical free-form surface is optimally utilized to enable the free-form surface to be freely modified and changed by adjusting the coefficients of the aspherical surface or the like. The light-diffusing LED lens enables a numerical design and a mathematical design by means of the free-form surface, and enables a fine control to be performed by numerical control to thus improve accuracy of light control.

The invention discloses a highway environment-friendly dust-reducing construction structure which comprises a vehicle frame. Moving Wheels are mounted at the bottom of the vehicle frame.

The invention relates to a construction vehicle tire cleaning device and belongs to the technical field of automatic control. The construction vehicle tire cleaning device comprises a water leaking frame, guide rails, water sprayers, a self-reflection infrared geminate transistor module and a control circuit; the guide rails are mounted on the two sides of the water leaking frame, the water sprayers are mounted on the guide rails, and the self-reflection infrared geminate transistor module is mounted at the top end of any water sprayer; the control circuit comprises a pressure sensor, relays, a counter, a solenoid valve, a direct-current motor and a combinational logic gate circuit; the self-reflection infrared geminate transistor module outputs a control signal to the counter, and an output signal of the counter controls the solenoid valve, the relay KM1, the relay KM3 and the relay KM2 to act through the combinational logic gate circuit, then controls the water sprayers to spray water and controls the direct-current motor to rotate forwardly or reversely or stop. The construction vehicle tire cleaning device solves the problem that the highway environment is contaminated when a construction vehicle comes in or goes out of a construction site because tires are stained with soil, and the tires of the construction vehicle can be cleaned easily and conveniently.

The invention discloses an automatic road risk assessment method. By collecting the road condition parameters of the highway and transforming the road condition parameters into a data form recognizable by a computer, the data is analyzed by using a multi-layer fusion deep network, and a road condition parameter reflecting road safety parameters is established. The deep neural network model of the relationship between risk levels is used to evaluate the safety risk of highways with unknown risk levels. Through the automatic highway risk assessment method of the present invention, various highway environment parameters can be analyzed and integrated by means of statistical learning, the relationship between highway risk levels and road condition parameters can be effectively extracted, and then the highway risk level can be automatically assessed.
