[0018] The implementation of the small roundabout three-dimensional guidance system based on right-of-way priority of the present invention has the following beneficial effects:

[0019] 1. This invention primarily uses shape to construct four types of arrow patterns: square, crescent, dart, and circular. Color, supplemented by red, green, yellow, and blue, is used. This scientifically combines color and shape with roundabout road sign information, integrating traffic facilities such as roundabout combined warning devices, pedestrian crossing lighting devices, and new vibrating speed reduction markings. This significantly improves the visibility and permanence of various traffic facilities. At the same time, by integrating a combination of various shapes and colors, the roundabout traffic environment is enriched, road right-of-way information is clarified, the visual recognition needs of drivers at different points on the roundabout are met, and a multi-level, complete roundabout driving information chain is provided, improving the efficiency and safety of roundabout traffic.

[0020] 2. This invention uses a four-color torch-type beacon, incorporating the corresponding colors and shapes of the branch roads, to create a strong visual reference system at the center of the roundabout. The beacon's pole rotates, guiding drivers to notice changes in the road's linear shape, while also reducing sight distance. The pole's base color and the self-luminous light bulb provide guidance, providing a preview of the next exit and improving drivers' sense of direction at the roundabout.

[0021] 3. The present invention uses a combination of traffic safety facilities such as crosswalk speed bumps, curb extensions, and new vibrating speed reduction markings to control the speed of vehicles in the physical area of ​​the roundabout, reducing the severity of traffic accidents and ensuring the safety of non-motor vehicles and pedestrians. At the same time, the comprehensive use of crosswalk speed bumps, curb extensions, and crosswalk warning signs clarifies the right of way for pedestrians crossing the street; the comprehensive use of colored serrated yield lines and new vibrating speed reduction markings clarifies the right of way for vehicles going around the roundabout; and the combination of Y-shaped path guidance markings, colored road surface guidance markings, and new road signs clarifies the right of way for vehicles exiting the roundabout, ensuring the orderly driving of vehicles around the roundabout.

[0022] 4. The wave-like guide poles set in the present invention, through the reasonable combination of pole height settings, make the poles appear undulating, giving the driver a sense of rhythm when driving around the island. The setting of the first pole further clarifies the driver's sense of direction, while the upward-facing guide marker reflective film in the middle and lower parts gives the driver a sense of dynamic forward movement; the second pole, the third pole and the fourth pole are combined to set three linear guide markers to outline the roundabout line. At the same time, the multi-level setting significantly improves the roundabout perception ability of drivers entering the roundabout, avoiding the occurrence of island collision accidents. The setting of the Belisa ball lights further ensures the safety of vehicle merging; the multi-layer downward-facing guide marker reflective film on the fifth pole is a strong reminder for vehicles leaving the roundabout, preventing drivers from missing the target exit;

[0023] 5. The new road sign of the present invention is equipped with a patterned road sign above, which improves the visibility of the sign. At the same time, the size difference between the arrows for exiting the loop and those for circling the loop highlights the priority right of way for exiting the loop. The arc-shaped road name indicator used in the upper middle part of the road sign has different sizes for the road names on the left and right sides, and the road name on the right side is perpendicular to the driver's line of sight. On the premise of meeting the driver's visual recognition conditions, it further highlights the priority right of way for exiting the loop. The two path guidance reflective films arranged at the bottom enrich the layering of visual information and meet the visual recognition needs of drivers at different points.
