  • Immersive simulation rooms (cars, motorcycles, pedestrians) - IFSTTAR COSYS/AME

    IFSTTAR’s immersive simulation rooms allow the Institute to conduct behavioural studies using a modular simulator that can be configured in two different ways. Either car driving is simulated using an instrumented vehicle that is surrounded by 9 projection screens which completely immerse the driver. Or, in order to simulate a pedestrian crossing a road, the participant moves physically over a distance of more than 7 metres. This pedestrian is fitted with movement sensors that allow his/her spatial position to be identified and modify the visual scenes projected on 10 very large screens depending on the pedestrian’s movements.

     

    Details about this facility can be found on the website of LEPSIS (Laboratory for Road Operations, Perception, Simulators and Simulations) which belongs to COSYS (IFFSTAR’s Components and Systems Department). This facility is also used by AME (the Planning, Mobilities and Environment Department)

  • Rail traffic supervision simulation platform - IFSTTAR COSYS

    The rail traffic supervision simulation platform enables IFFSTAR to assess some of the components of the European Rail Traffic Management System (ERTMS). It consists of three systems: a driving simulator with a driver’s desk that can be used in tandem with a 3D representation of a line, a traffic simulator that acts both as a control centre for railway traffic and train management and, last, a test bench to which an on-board ERTMS can be connected in order to check compliance with ERTMS specifications and national operating rules.

  • Driving simulators for analysing the impact of internal and external factors (alcohol, medicines, infrastructure, information etc.) on driver behaviours and analyzing human-machine interactions - IFSTTAR COSYS/TS2

    The driving simulators at Bron and Salon-de-Provence allow IFSTTAR to analyse driver behaviours caused by internal factors (anger, sadness, for example) or external factors (in the environment) and study driver-vehicle interactions. These fixed-base cab simulators are instrumented with sensors fitted to the controls. The car’s communication bus (CAN bus) is also used to process dashboard information. The image of the road scene that is projected on 5 screens to the front presents a visual field covering 200 degrees horizontally and 40 degrees vertically. The simulators also have a device that allows the driver to see behind with rear-view mirrors. Last, the cab is equipped with quadraphonic sound that reproduces the internal noise of the vehicle (motor, rolling noise, starter) and external (spatialised) traffic noises.

     

    Details of this facility are available on the website of LEPSIS (Laboratory of Ergonomics and Cognitive Sciences applied to Transport) which belongs to COSYS (IFSTTAR’s Components and systems Department). This facility is also used by TS2 (the Transport, Health and Safety Department). Examples of studies can be found on the website of LESCOT (Laboratory Ergonomics and Cognitive Sciences applied to Transport)

  • Integrative simulation platform for drivers and human-machine systems: design and appraisal of driving aids - IFSTTAR TS2

    PSICO-SYHM is a human-centred virtual platform for designing the driving aids of the future with a view to specifying the ergonomic characteristics they will need to meet users’ requirements and expectations. It can either be used as a mini driving simulator, in which humans drive a vehicle fitted with virtual assistance systems (using the SiVIC model), or as a tool that drives a virtual vehicle (which may or may not be fitted with simulated systems of the above type), by a driver model known as COSMODRIVE. It also enables IFSTTAR to assess how future driver assistance systems will integrate within the driving activity and improve road safety, as well as to identify the situations in which assistance is particularly beneficial and evaluate, in a virtual environment, the impact of these systems once they have been installed in the vehicle.

  • Environmental simulation and evaluation laboratory - IFSTTAR AME

    The Environmental simulation and evaluation laboratory allows IFSTTAR to immerse individuals in an environment that closely resembles that of someone living near a piece of transport infrastructure by simulating situations that may or may not exist in reality. It includes a furnished room in which the environment is reproduced using the techniques of audio-visual reproduction. The images and sound are generated by an audio-visual module such that they coincide with the window. The image is obtained by projection onto a screen that fits the window frame and the sound is reproduced by a 16 loudspeaker system behind the screen that reproduces the wave front. The content is controlled from an audio-visual control unit.

  • Bicycle simulator

    Ifsttar’s bicycle simulator was built by placing a real bicycle on a platform. Two force-feedback systems provide haptic feedback: one in the handlebar and the other in the rear wheel. The inertia experienced by riders when they start or stop pedalling is produced by a flywheel. A fan, placed in front of the bicycle, simulates the air which flows by the rider in real situation; the flow rate is controlled during the simulation as a function of the speed. The bicycle can be slightly tilted thanks to a passive mechanical system. Finally, participants’ actions can be measured and logged, including their actions on the gear and the brake levers.
