For varying road conditions, different illuminated signs must be selected to achieve optimal warning and guiding effects.
Areas should be equipped with active illumination signs.
1. Tunnel interior
2. Freeway Short Radius Curve
Interchange with a small-radius ramp
4. School and hospital entrance and exit areas
5. Main and secondary roads running east-west prone to "backlight" phenomena.
5. Other road segments with potential traffic safety hazards
The following areas are recommended for the installation of active发光signs.
Poor visibility or excessively wide observation angle at intersections
2. Poor night lighting conditions and road sections with traffic safety hazards
3. Complex background lighting sections along roadways and intersections
4. Sharp decline
5. Bridge entrance on ground-level road
Section III: Active发光signs can be installed in the following areas.
1. Urban roadways with poor or overexposed lighting conditions at night, such as areas adjacent to streetlights, beneath large billboard lighting boxes, and under projectors.
2. Poor visibility or excessively wide observation angles on road sections and intersections
