Retroreflectometers for Road Markings and Traffic Signs
TBTSCIETECH supplies handheld and vehicle-mounted retroreflectometers for road marking inspection, as well as handheld instruments for traffic sign testing. Compare instruments for spot measurements, continuous road surveys, and sign sheeting inspection.
Test pavement markings at individual locations or collect continuous measurements along a route. Handheld instruments support spot checks, while vehicle-mounted systems help survey longer road sections.

Road Marking and Traffic Sign Inspection Solution
Headlight Simulation
The road marking retroreflectometer uses a defined lighting and viewing geometry to simulate how drivers see pavement markings illuminated by vehicle headlights.
Nighttime Marking Visibility (Rₗ)
Measure the coefficient of retroreflected luminance (Rₗ) of pavement markings. Use the readings to assess nighttime visibility and identify sections that may need repainting.
Daytime Marking Visibility (Qᵈ)
Models with Qᵈ capability measure the luminance coefficient under diffuse illumination. The readings help assess how visible pavement markings are in daylight.
Traffic Sign Retroreflectivity (Rₐ)
A traffic sign retroreflectometer measures the coefficient of retroreflection (Rₐ) of sign sheeting at specified angles. Use the readings to document sign condition during roadside inspections.
Road Marking and Traffic Sign Inspection Applications
Road maintenance teams and project inspectors use retroreflectometers to assess pavement markings, prioritize repainting, and verify newly installed traffic signs against project requirements.
Nighttime Pavement Marking Surveys
Road maintenance teams measure pavement marking retroreflectivity (RL) at selected locations during routine surveys. Comparing readings with project criteria helps identify sections for follow-up inspection or repainting.
Wet Pavement Marking Testing
When a project specifies wet-condition testing, inspectors measure pavement marking retroreflectivity (RL) using an instrument that supports the required test method. The readings help identify markings that may be difficult to see under headlight illumination when wet.
Traffic Sign Acceptance Testing
Before accepting newly installed traffic signs, inspectors measure the coefficient of retroreflection (RA) of the sign sheeting at specified angles. They compare the readings with project requirements and record the results in the acceptance report.
Benefits of Road Marking and Traffic Sign Inspection
Document Inspection Results
Record retroreflectivity readings for pavement markings and traffic sign sheeting. Include the inspection location and test conditions so project teams can compare results with acceptance criteria, document findings, and refer back to them during future inspections.
Prioritize Repainting
Compare road marking readings across road sections to identify where repainting is most urgent. Use the results to schedule work and allocate maintenance budgets to the sections that need attention first.
Assess Wet-Weather Visibility
Where wet-condition testing is specified, use a compatible retroreflectometer to measure pavement marking retroreflectivity (RL). The results help teams flag sections for follow-up where wet markings may be harder to see under headlights.

Road Marking and Traffic Sign Inspection FAQs
What is the difference between RL, Qd, and RA?
RL measures how brightly pavement markings appear under vehicle headlights at night. Qd measures how visible pavement markings are under diffuse lighting, such as daylight. RA measures the retroreflectivity of traffic sign sheeting at specified observation and entrance angles.
When are handheld and vehicle-mounted retroreflectometers used?
Can a road marking retroreflectometer measure wet markings?
How is retroreflectivity checked during traffic sign acceptance testing?
