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.

Description

A MULTIFUNCTION

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.

LIDAR

  • 350° sensor
  • 2 million points / second
  • Profile spacing:
    14 mm at 10km/h
    70 mm at 50km/h
    120mm at 90km/h

Distance measurements

  • Sensor: Optical encoder, 5,000 pulses per wheel revolution
  • Accuracy: ≤ 0.2%, Resolution: 0.4 mm
  • Indicator: distance traveled, system synchronisation

GPS / inertial system (hybrid dual GPS positioning system coupled with an inertial unit)

  • High-end positioning system
  • Allows continuity of positioning in case of masking
  • Possibility of differential correction in real time
  • Post-processing of GPS data to improve accuracy (at least 3 days after the measurements)
  • X, Y positioning accuracy between 2 m and a few cm
