About this study

Official title: On the Highway to Autonomous Driving: How is Automation Changing Humans: Investigations of Drivers' Behaviors, Representations and Neural Processes

In the context of ever-increasing automation in surface vehicles, automation impact on drivers will be investigated through three complementary research axes undertaken under simulated driving:

Axe 1 (Cognitive ergonomics), how automation is impacting driving behaviors and visual explorations? Axe 2 (Experimental psychology), how automation is impacting drivers' mental representations of their own driving abilities? Axe 3 (Neuroimaging), how automation is modifying the car driving neural network? And what are drivers' mental representations neural bases? The project tackle both applied and basic research issues using an original experimental neuro ergonomics approach. AUTODRIVE will bring original data on human-machine cooperation, mental representations, cognitive control and brain processes depending on the characteristics of the automation used over a significant period of time (six weeks) on a large sample (N=120) of experienced and inexperienced drivers.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Level of vehicle automationDevice

    From no automation of the vehicle to full automation through warnings, shared control and partly automated automation levels.

Study groups in NCT03893006
Study groupRoleWhat they receive
UnAssisted (UA)ExperimentalThis term refers to driving a vehicle manually without any vehicle automation technology. It will serve as a baseline concerning behaviors, representations and neural results associated with unassisted automobile driving.
Receives: Device: Level of vehicle automation
Assisted (A)ExperimentalThis term refers to driving with warning technology which upon activation sounds an a warning when the vehicle is too close to the edge of the road (off-road warning , Navarro, Mars, \& Hoc, 2007; Suzuki \& Jansson, 2003) or too close to the vehicle in front of it (anti-collision warning; Lee, McGehee, Brown, \& Reyes, 2002).
Receives: Device: Level of vehicle automation
Shared Control (SC)ExperimentalThis term refers to shared tactical control between the driver and the automated assistive technology, both working simultaneously on the physical trajectory of the vehicle, laterally (Griffiths \& Gillespie, 2005; Mulder, Abbink, \& Boer, 2012) as well as longitudinal (Adell, Várhelyi, \& Hjälmdahl, 2008).
Receives: Device: Level of vehicle automation
Partly Autonomous (PA)ExperimentalThis term refers to a situation where the lateral and longitudinal control of the driving are delegated to the automated assistive technology. It consists of a level of automatisation that today is possible to put into application and which often is referred to by the name "Highly Automated Driving" (Navarro, 2018). In this case, the driver is no longer the one who physically ensures the lateral and longitudinal control of the vehicle, but instead supervises the actions of the automated assistive technology.
Receives: Device: Level of vehicle automation
Fully Autonomous (FA)ExperimentalThis term refers to a completely automated driving experience. The on-board technologies take over all the driving tasks for any driving situation.
Receives: Device: Level of vehicle automation
Any Automation (AA)ExperimentalThis term refers to a situation where the drivers can choose the automation device of their choice among the five types presented above and can change it whenever they think it is good to do so.
Receives: Device: Level of vehicle automation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. BOLD effect

    Functional magnetic resonance imaging measures brain activity by detecting changes associated with blood flow This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast in response to an experimental condition (Ogawa, Lee, Kay, \& Tank, 1990), allowing researchers to track changes in oxygen consumption on the brain, and therefore brain activity. BOLD effect is computed by assessing the different relaxation times (T1 and T2) in the brain, as T1 and T2 are different in function of regional cerebral blood flows.

    The outcome will be a change between mean BOLD effect oven session 1 versus session 2 versus session 3.

    Measured: Repetition Time (TR) :every 3 seconds, during the 3 fMRI sessions of respectively 1 hour, 0,75 hour and 0,75 hour. fMRI session 2 occurs 3 weeks after fMRI session 1 and 3 weeks before fMRI session 3.

Secondary outcomes (1)
  1. Behavioral changes

    Participants will be asked to drive through a variety of driving situations in a driving simulator simulated environment equipped with an eye-tracker. The measure collected will be drivers' behaviors on the steering wheel and pedals as well as their visual behaviors.

    The outcome will be a change in the number of actions on the steering wheel (a), pedals (b) and gaze dispersion (c) on the visual scene across the time points.

    Measured: Two experimental sessions of an hour, one before and one after the six weeks of automated driving. Plus six driving sessions of 0,5 hour, one driving session the first day of each experimental week.

Questions about this trial

What is this clinical trial studying?

A study of Behaviors and Driving, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jordan Navarro, MD (00 33 4 78 77 30 52, jordan.navarro@univ-lyon2.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BOLD effect (time frame: Repetition Time (TR) :every 3 seconds, during the 3 fMRI sessions of respectively 1 hour, 0,75 hour and 0,75 hour. fMRI session 2 occurs 3 weeks after fMRI session 1 and 3 weeks before fMRI session 3.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2021.
