This utility model relates to the field of road guardrail technology, and in particular to an adjustable guardrail for highway traffic safety. It includes two mounting bases, each with four casters at its lower corners. The adjustable guardrail of this utility model allows for easy movement to a designated position via the casters. Turning the lever activates a screw to drive a clamping plate, fixing the abrasive block to the ground. When length adjustment is needed, pushing the support rod allows the extension frame to slide out, embedding the extension component and adjusting it using fixing bolts and pins. When a required height is needed on the highway, a motor, gears, and racks work together to slide a guide plate, moving the crossbar and extending / retracting the extension guardrail, simultaneously adjusting the position of the second extension guardrail. This allows for flexible and precise adjustment of the guardrail's length and height, effectively addressing the diverse needs of different construction areas and complex highway environments, improving adaptability and efficiency.

The utility model discloses an adjustable highway sound barrier relates to sound barrier technical field, including vertical positioning frame, the inner wall movable insertion of vertical positioning frame has from below and upwards laminated first combination barrier and second combination barrier, and the contact end movable joint of first combination barrier and second combination barrier, first combination barrier includes positioning board and turnover board. The utility model discloses through the positioning board and turnover board of first combination barrier can rotate around axle rod, can arrange vertically up and down, form conventional sound barrier structure, satisfy general noise reduction demand, can also stack in front and back, form thickening structure, when facing high noise road section or special noise environment, can effectively improve the noise reduction effect. Meanwhile, first combination barrier and second combination barrier also can be adjusted through movable joint, and this kind of multi -mode adjustment function makes sound barrier can according to different highway environment, noise intensity factor, adjusts structure flexibly.

This application discloses a method for correcting misjudgments in high-speed multi-type event detection based on LoRA, relating to the field of intelligent transportation technology. The method includes: acquiring real-time event information on the highway, identifying it using the YOLO algorithm, and outputting the original preliminary event detection results and environmental parameters; standardizing the preliminary detection results and extracting semantic and scene features of the event targets from the preliminary detection results to obtain standard preliminary detection results; performing secondary verification and misjudgment correction using a LoRA-optimized large model based on the standard preliminary detection results to obtain the event detection results; uploading the event detection results to the road segment central monitoring platform, and retaining misjudged, missed, and new scene samples for iterative optimization. This application aims to resolve the contradiction between the low reliability of event detection in complex highway environments and the inability to deploy high-precision large models at low cost and high efficiency under existing hardware conditions.

The application relates to a highway environment-friendly structure and relates to the technical field of road environment protection. The highway environment-friendly structure comprises a plurality of channel bases connected in sequence, the channel bases are used for planting green plants, water flow holes are formed in the bottoms of the channel bases, the water flow holes of adjacent two channel bases are communicated, the water flow hole of the channel base at the head end is communicated with a water pump, the water pump is communicated with a water tank, the channel base at the tail end is communicated with the water tank through a pipeline, the water tank is used for storing water, a collecting hole for collecting rainwater is formed between the top end of the channel base and the water flow hole, the water flow hole and the channel base are internally provided with water supply holes for water supply, and the channel base is provided with an adjusting assembly for adjusting the closing or opening of the water supply holes and the water flow holes; when the channel base lacks water, the adjusting assembly makes the water supply holes open and the water flow holes close; and when the channel base stores water, the adjusting assembly makes the water supply holes close and the water flow holes open. The application has the effect of stably supplying water to the highway green vegetation layer for a long time.

This invention provides a multi-expert autonomous behavior decision-making method for highways based on scene-aware constraints, belonging to the field of autonomous driving technology. It includes: constructing a one-way three-lane straight highway environment; using a bicycle model to describe vehicle kinematics; employing an IDM model to model the longitudinal following behavior of surrounding vehicles, forming a traffic flow with a certain degree of randomness and uncertainty; dividing the driving scenario into multiple sub-scenarios; constructing a unified state space and action space; designing a unified scene constraint cost for each sub-scenarios; introducing scene-aware constraints, improving the DRL algorithm used for each sub-scenarios, and training a corresponding expert model based on the scene-aware constraint SAC algorithm; constructing training and testing sets; and conducting actual operation or simulation testing.
