EASY examined how some of the new Advanced Driver Assistance Systems that are envisaged by car manufacturers affect safety. A systematic evaluation of drivers' performance and safety awareness as they experience increasingly greater automation of the driving task was conducted.


The major objectives of the project are:

  • To understand the human factors and safety implications of ADAS that supplant the driver in control of the vehicle
  • To investigate the effects of various type of ADAS - those that take over longitudinal control, those take over lateral control and a combination of the two
  • To develop means for mitigating any negative safety implications of such systems, so that their potential benefits in terms of increased capacity of the road network and increased reliability over the human operator can be realised.


EASY conducted two major experiments to examine the impact of semi-automated and fully automated driving on driver attention allocation, situation awareness and ability to react in demanding situations. In the first experiment, drivers were given the freedom to choose how much attention to pay to the driving task and how much attention to pay to various entertainment and information tasks. In the second experiment, behaviour in normal traffic and in more demanding incidents was compared. The final experiment in the project looked at mitigation strategies for bringing the driver back into the loop. A simple time-based procedure was compared to a procedure based on a real-time attention monitor.
