Road markings are traffic signs according to § 41 Para. 3 and § 42 Para. 6 StVO (German Road Traffic Regulations) and Section 2 of the ‘Guidelines for Road Marking, Part 1’ (RMS-1). In darkness, markings, particularly on open sections of road, have an important guiding function, as road users have no other means of orientation to call upon.
Road markings are subject to different external influences which lead to a degradation of their traffic-related properties. For decades DELTA has been the world’s leading manufacturer of portable and dynamic systems for the precise and rapid measurement of daytime (Qd) and night-time visibility (RL) and contrast.
We offer various measuring systems for measuring the photometric properties of markings statically and dynamically, all of which can be configured to suit the individual customer.
Test institutions, highway construction authorities and marketing companies require different measuring instruments for testing traffic-related properties, and TDS offers these in the form of a test kit to meet customers’ individual requirements. A mechanical and a digital marking thickness gauge are available for measuring the layer thickness of dry markings (with and without reflective beads)

The TOP ROAD001 retroreflectometer is the latest generation. It is a highly compact instrument for measuring the night-time visibility (RL) and, optionally, the daytime visibility (Qd) of road markings. Measurements can be taken both in the daytime and at night on dry and wet markings.
The TOP ROAD001 optionally fulfils the requirements of DIN EN 1436 or ASTM E 1710. The scope of supply includes a calibration stand (RL) and a calibration reference (Qd) from DELTA’s photometry calibration laboratory, which is accredited by DANAK. The following extras are available as an option:
