ECODYN 3 – Daytime and night visibility of road markings

logo-mlpc EN 1436


Continuous and dynamic measurement of road marking performance (Retroreflection – RL).


Device qualified mlpc®


Demander des informations


The first mobile retro-reflectometer capable of measuring two lines simultaneously at traffic speed. Road markings guide and secure road users, especially at night. Subjected to traffic and climate, markings become less visible. In order to maintain an accessible and legible road for drivers and vehicle assistance systems, road managers must ensure that road markings are regularly maintained.

Ecodyn 3 allows to evaluate objectively and accurately the quality of longitudinal road markings (center lines, edge lines), according to the EN 1436 standard. It is capable of measuring (by day or night) the night visibility of road markings (retro-reflection RL). It thus provides the necessary information to program preventive renewal campaigns, to control the quality of the implementation of marking products and to follow their evolution over time.

ECODYN, the first device capable of measuring dynamically the retro-reflection of markings, has been widely distributed throughout the world. ECODYN was the successor of the ECOLUX, the first portable reflectometer capable of measuring the retro-reflection of markings in static.

In keeping with this heritage of technical excellence and innovation, the third generation ECODYN 3 is the first in the world to offer LED lighting technologies and to allow the simultaneous measurement of two marking lines (axis + edges).

→ The device is more compact than previous generations. The measuring width for easy driving in single or dual band operation.
→ The measurement is continuous and can be carried out from 0 to 130Km/h without data loss.


→ Data acquisition carried out at traffic speed using one or two simultaneous heads: halves the costs of personnel, fuel and vehicle use compared to other lateral systems.
→ Simplified human-machine interface with event keyboard to lighten the workload of the device operator.


Metrological quality
→ mlpc® qualification: developed in partnership with the UGE (formerly LCPC) and CEREMA,
ECODYN 3 has been metrologically qualified, which attests to its compliance with the requirements of standard EN 1436.
→ Integrated architecture of the measuring head (LED, optical fibres, filtering, detection, digital electronics, computer network…) facilitating the metrological integrity of the data
→ For each device, the national verification centre ensures an accurate and connected calibration.


→ LED technology significantly reducing power constraints and increasing measurement stability.
→ Vehicle integration (anchoring, connectivity) maximising operational reliability.
