Assisting in the management, evaluation and preservation of the road network

Our multifunctionals are multifunctional vehicles used for the following applications:

  • Measures concrete and metal guardrail heights
  • Measures free heights under structures
  • Measures superelevation of a formation level and of each lane

SYMAN is a multifunctional device designed and manufactured according to the requirements and needs of road and motorway managers.

SYMAN (SYstème Multifonction d’ANalyse) is a device capable of acquiring in a single pass all the data at the speed of traffic (road and motorway).

This device is equipped with a LIDAR (Lighthouse Detection And Ranging) function that allows the detection and measurement of objects near the pavement or the pavement itself continuously in the traffic flow.

We work with you to design the multifunctional condition survey equipment you need. Your multifunctional device can be equipped with:

  • 360° camera (heritage + environment survey)
  • GPS
  • Pavement geometry sensors
  • Sensors for macrotexture
  • Sensors for the longitudinal profile
  • Sensors for the transverse profile
  • Sensors for automatic reading in images
  • etc.

Based on the experience of the design of several multifunctions: AMAC®, SYMAN®, Multifunction LTPO, we will be able to offer you a made-to-measure, efficient and precise vehicle.
