Monitor the performance of road markings and traffic signs with retroreflectometer instruments to ensure road traffic safety – and improve the safety of road traffic.

Road markings are essential for road safety

Proper performing road markings and traffic signs are important aids to ensure safe traffic flow, thus minimising the number of traffic accidents and fatalities on roads worldwide. Especially at nighttime and during wet and rainy conditions, when the visibility is reduced, road markings and signs are important guidance for drivers to stay safely on the road avoiding accidents.

Ensure road markings perform properly

Road markings are not merely a cost for the road owner. Well-functioning road markings and signs can keep the number of road accidents at a minimum. 

A retroreflectometer allows you to monitor the performance of road markings. By knowing the condition of road markings and signs, road owners can make sensible decisions related to road maintenance and optimise their maintenance budgets.

Dedicated to road traffic safety worldwide

DELTA RoadSensors (a part of FORCE Technology) develops and provides highly reliable retroreflectometers used for measuring retroreflection of:
