Fixed, Vertical Road Traffic Signs - Part 2: Transilluminated Traffic Bollards (TTB)
Also Known As:
The DIN EN 12899-2 standard focuses on transilluminated traffic bollards (TTBs) designed for fixed, vertical road traffic signs. It specifies the requirements for these TTBs, including their installation and fixing methods. The standard distinguishes between two types of TTBs: type 1 which incorporate traffic signs and type 2 which support traffic signs.
One of the key aspects covered in this standard is the performance requirements for TTBs. This includes specifying colorimetric and retroreflective properties, as well as the luminance of the electrically illuminated portions of the TTBs. These requirements take into account recommendations from the International Commission on Illumination (CIE).
In addition to performance requirements, the standard also addresses the structural properties of TTBs. This includes requirements for both static and dynamic loading, ensuring that the TTBs can withstand various environmental conditions and potential impacts.
Lastly, the standard takes into consideration safety aspects and includes provisions for ensuring the TTBs are safe to use. This ensures that TTBs are not only effective in conveying traffic information but also meet safety standards for their installation and use on roads.
