This utility model discloses a nighttime driving safety enhancement device at the nose of a highway, belonging to the field of highway traffic safety technology. This utility model uses nighttime vision guidance components deployed on the mainline and ramp guardrails in a designated area to continuously guide drivers in anticipating changes in traffic flow, preventing sudden accidents. Illuminated warning components behind the small nose point alert drivers to entering critical areas, while reflective guide components in front help predict road direction. Warm yellow and pure white guidance lights are respectively installed on the left and right sides to help determine road boundaries, with continuous lighting guiding the driver's line of sight along the road. A segmented guidance system is adopted: constant illumination at long distances provides stable guidance, flashing at medium distances enhances warnings, and constant illumination at close distances reduces visual fatigue. This effectively solves the problem of unstable visibility and warning effects of existing devices in the nose area at night and in low-visibility environments, and ensures guidance effectiveness under adverse conditions through a combination of active and passive illumination.
