Retroreflectivity Measuring Devices
At Strinso, we offer retroreflection assessment equipment and specialized solutions to measure road marking retroreflectivity, a key factor in ensuring safety on highways and urban roads, both day and night. With state-of-the-art equipment, you can ensure that all horizontal and vertical signage complies with official retroreflection standards.
Cutting-edge technology to test the visibility of road markings, traffic signs, and airport signage. In an era of autonomous vehicles that rely on well-maintained pavement markings, establishing greater uniformity and higher standards is more critical than ever. Measure the retroreflectivity of road markings, signs, and other reflective materials accurately and efficiently with retroreflectometers and intelligent mapping software, ensuring full traceability and real-time data sharing.
What is retroreflection and why is it important?
Retroreflection is the ability of a surface to return light to its source, which increases the visibility of road signage under nighttime, rainy, or wet conditions. This is achieved through retroreflective materials, such as microprisms in vertical signs and glass beads in horizontal markings, which reflect and refract light to ensure they are visible to drivers.
How is Retroreflectivity Measured?
“To measure road marking retroreflectivity, specialized equipment called retroreflectometers are used. These devices evaluate three types of reflection
- Nighttime retroreflection: Measures the light that returns to its source of origin
- Daytime diffuse reflection: Evaluates light reflected in all directions.
- Specular reflection: Analyzes visibility under rainy or wet conditions.
How much should vertical signage or pedestrian crossings measure?
According to international regulations, the minimum retroreflectivity of road signs and markings varies depending on their color, location, and material type. For example:
- Vertical signage: Standards establish specific values for colors such as white, yellow, or red, which guarantee adequate visibility.
- Pedestrian crossings and horizontal markings: Retroreflectivity must ensure they are visible to drivers, especially under low-light conditions.
Retrorreflexividade horizontal: chaves para garantir visibilidade
Horizontal markings, such as pedestrian crossings or lane dividers, rely on glass beads that reflect light back to drivers. Factors like wear, dirt, or color can affect their retroreflectivity levels. With our equipment, you can perform periodic evaluations and maintain signage quality.
