A visual safety guide device for a highway tunnel
By installing reflective modules at the top of the tunnel, the reflective effect guides the driver's line of sight, solving the problem of the lack of guidance devices at the front of the tunnel. This enables safe guidance for drivers with poor vision or astigmatism, and avoids collision accidents.

AI Technical Summary
Technical Problem
Existing highway tunnels lack effective guidance devices at the front end, which obstructs or distracts drivers' vision, making it easy for drivers with poor tunnel vision or astigmatism to crash into the walls at the road divergence point.
Method used
Reflective modules are installed at the top of the tunnel and fixed to the wall using spring bolt assemblies. The reflective effect of the modules guides the driver's line of sight, especially providing clear visual guidance when there is insufficient light or obstructed vision in the tunnel.
Benefits of technology
It effectively avoids collisions caused by obstructed vision or momentary distraction, and provides clearer visual guidance, especially for drivers with poor eyesight or astigmatism, ensuring driving safety.

Abstract
This utility model provides a visual safety guidance device for highway tunnels, relating to the technical field of tunnel guidance devices. It includes a mounting frame installed at the top of the tunnel facing the centerline of the wall at the diversion point, and several reflective modules mounted on the mounting frame. The mounting frame has inverted buckle portions on both sides of its bottom, and recessed holes are equidistantly spaced on the mounting frame, with spring bolt assemblies installed within these recessed holes. Each reflective module consists of a mounting base and a reflector, which are fixed together by bolts. The mounting base has a snap-fit groove extending to both ends on one side corresponding to the recessed hole. This device is installed at the top of the tunnel, connecting to the diversion point at the tunnel's front end. Through the tunnel's lighting and the reflection from the reflectors, it effectively guides the driver's line of sight at the tunnel's front end, preventing collisions caused by obstructed vision or momentary distraction, especially for drivers with poor vision or astigmatism.
